How to Cross the Border from Lao Cai to Hekou (Vietnam to China)

how to go from lao cai to hekou

Crossing from Vietnam into China at the Lao Cai–Hekou border is one of the easiest ways to travel between the two countries. Whether you’re heading from Sapa to Kunming, planning a longer trip through Yunnan Province, or simply looking for an overland route into China, this border crossing is straightforward and well used by both locals and international travelers.  While we originally crossed this border in 2014, this post is updated after our 2026 visit to China.  There have been a few changes over the years, but this post is now updated for today’s travelers, and I’ll cover everything you need to know about crossing the border from Lao Cai to Hekou, including transportation from Sapa, immigration procedures, visas, money, onward travel, and practical tips to make your journey as smooth as possible.

The Lao Cai–Hekou crossing is located on the border between northern Vietnam and China’s Yunnan Province and avoids the need for flights.  Once across the border, you’ll have access to China’s extensive high-speed rail network, making destinations such as Kunming, Dali, Lijiang, and Shangri-La easily accessible.  This border crossing is still not particularly busy and is usually a quick and easy crossing to make.

PRACTICAL TRAVEL TIPS

However, the first thing that you’re going to want to do is read this guide thoroughly – ask any questions you might have and plan out your onward travel from Hekou.  This is especially the case if you do not have a VPN.  China is currently blocking access to all HTTPS websites ( so that means this site as well as all the sites where you’d book your accommodation, trains, and other onward travel ) Read more about VPNs and other things you should do BEFORE you get to China in our article.

Why Cross the Border at Lao Cai and Hekou?

If you’re exploring northern Vietnam and southern China, then the Lao Cai–Hekou border crossing is by far the most convenient overland route between the two countries. It connects the popular destination of Sapa with China’s Yunnan Province and provides easy access to cities such as Kunming, Dali, and Lijiang.  We chose this route so that we could visit the rice terraces of Yuanyang, and then head towards Tiger Leaping Gorge, Lijiang, and Shangri-La (and I recommend all of them!)

The Main Border Crossing Between Vietnam and China

The Lao Cai–Hekou border crossing is one of the busiest and most important land borders between Vietnam and China.  On the Vietnamese side, you’ll find the city of Lao Cai, while Hekou is directly across the border in China’s Yunnan Province. The two cities are separated by the Nanxi River and connected by an international border crossing that can be crossed on foot. 

I do think there is something fabulous about walking across borders, and this is a simple border to walk across.

Is the Lao Cai Hekou Border Open?

I’m including this high up in this blog post, because the Lao Cai Hekou border was closed for several years, and it was the most asked question I got here on ASocialNomad.  (It was a COVID closure. 

However, yes, the Lao Cai–Hekou border is open to international travelers. This border was closed for a significant time during COVID, but is now fully open.

In normal circumstances, the border crossing process is straightforward and can usually be completed in less than an hour.

Where is the Lao Cai Hekou Border Crossing?

The Lao Cai–Hekou border crossing sits between northern Vietnam and China’s Yunnan Province and is the most popular land crossing for travelers moving between Sapa and southern China.

Where is Lao Cai?

Lao Cai is a city in northern Vietnam, located close to the Chinese border.  The train station here is the last stop in northern Vietnam (travel here from Hanoi easily on the overnight train), and is most commonly used by those visiting Sapa.  (Read my guide to Sapa here)

Most international visitors pass through Lao Cai on their way to or from Sapa, which is approximately 35 kilometers (21 miles) away in the mountains. While many travelers don’t spend much time in Lao Cai itself, it serves as the main transport hub for trains, buses, and border crossings in the region.

If you’re arriving on the train from Hanoi into Lao Cai and planning on going straight to the border, then the Lao Cai border crossing is about 2 kilometers (1.2 miles) from the Lao Cai train station.

Where is Sapa with regard to the Chinese Border Crossing?

Sapa is approximately 35 kilometers (21 miles) from the Lao Cai–Hekou border crossing.  You will have passed through Lao Cai on your way to Sapa. 

The journey between Sapa and Lao Cai usually takes between 45 minutes and an hour, depending on traffic and your chosen mode of transport. Buses, shared minivans, private cars, and taxis all operate regularly between the two destinations.  You can check the bus, shuttle, and taxi options to go from Sapa to Lao Cai and the border here.

Where is Hekou?

Hekou is a border town in Yunnan Province, China, located directly across the river from Lao Cai.  There are several cities and towns in China called Hekou.  The Hekou that you are heading to is Hekou, Yunnan Province.

Most travelers who make this border crossing from Vietnam into China are heading to Kunming, and try to get there the same day (it is entirely possible).  However, Hekou is a useful place to spend a night if your train connection doesn’t line up with your border crossing time.  If you’re heading to the rice fields of Yuangyang, then you may need to spend the night, as the transport heading there does NOT always line up with the border opening times.

Hekou, Yunnan, is a decent-sized town with a connection to the Chinese fast train network at Hekou North. There is also a good choice of hotels, restaurants, banks, ATMs, and shops.  It is an easy and somewhat laid-back introduction to China.

Once you’re here in Hekou, you can access China’s high-speed rail network via Hekou North Railway Station and continue your journey deeper into Yunnan Province.  Booking your onward train is something you’re going to want to do ASAP, as these pretty much all Chinese trains get booked out quickly.

How to Get from Sapa to the China Border

If you’re traveling from Sapa to China, the first step is getting from Sapa to Lao Cai. This route is well served by buses and taxis, making it easy to reach the border crossing regardless of your budget or travel style.

Sapa to Lao Cai by Bus

The cheapest and most popular way to travel from Sapa to Lao Cai is by bus.  Local buses and tourist shuttle buses operate throughout the day between the two destinations. The journey typically takes between 45 minutes and 90 minutes, depending on traffic and weather conditions.

Most buses drop passengers close to the center of Lao Cai, from where it’s a short taxi ride or walk to the border crossing, although some (like this one) will take you right to the border crossing.

Sapa to Lao Cai by Taxi

Taxis provide the fastest and most convenient way to travel between Sapa and Lao Cai.  The journey usually takes around 40 minutes and offers flexibility if you’re trying to reach the border at a specific time. This option is particularly useful if you’re traveling with heavy luggage, in a small group where the fare can be shared, or, my current favorite, just can’t be bothered with the hassle of the local bus.  Grab, the ride-hailing service, is available in Sapa, but services are particularly limited.  I would NOT rely on it to get to the border.  Book yourself a transfer, taxi, or bus instead.

Crossing the Border from Lao Cai to Hekou

Crossing from Vietnam into China at Lao Cai and Hekou is relatively straightforward, but it can feel a little intimidating, even if you’ve crossed land borders in Asia before. Chinese immigration is a tad intimidating.  However, the process is well organized and clearly signposted once you arrive.

When we made the crossing, the biggest challenge was the paperwork.  In 2014, when we first used this border crossing, we needed a physical visa, which meant a trip to the Chinese embassy in London.  Now it’s a whole lot easier with visa-free entry for so many countries, including the UK.   If you need a visa (Americans, I’m looking at you… then make it easy and use iVisa here)

That said.  No matter how easy it is, border crossing is always slightly daunting, so here’s a step-by-step guide to how it goes.  It’s important to note that there is a time zone change – China is one hour ahead of Vietnam.  China runs on a single timezone, aka Beijing time.

Arriving at the Vietnamese Immigration Checkpoint

Once you reach Lao Cai, make your way to the international border crossing. Most taxi drivers and local bus operators know exactly where to drop passengers heading into China.  And once you arrive here its pretty obvious too.  Depending on the time of day, there can be queues to enter the immigration area. Weekends, holidays, and peak travel periods can be particularly busy. 

It’s always best, when crossing borders, to get there as early in the day as you can.

Exiting Vietnam

The first step is passing through Vietnamese immigration, i.e., exiting Vietnam.

Lao Cai to Hekou Vietnamese Exit

After presenting your passport, you’ll receive an exit stamp allowing you to leave Vietnam. Immigration officers may ask a few simple questions about your travel plans, although in many cases the process takes only a few minutes, and they won’t even talk to you at all.

Once you’ve been stamped out of Vietnam, you’ll continue toward the border bridge connecting Lao Cai and Hekou.

Crossing the Bridge into China

After clearing Vietnamese immigration, you’ll walk across the bridge into China.

Walking Across the Friendship Bridge Lao CAi to Hekou

This, for me, is one of the coolest parts of walking across borders, walking across a river.  Well, walking across a bridge over a river.  The walk itself is short and straightforward, and you’ll simply follow the signs and the flow of other travelers heading toward Chinese immigration.

Entering China at Hekou

After crossing the bridge, you’ll enter the Chinese immigration complex in Hekou.

Immigration procedures on the Chinese side are generally more thorough than on the Vietnamese side.  

There’s usually a health check first.  You may be asked questions about your general health, if you’ve been sick, and all that.  The best answer, of course, is the truth, but equally, NOT being sick is going to get you into China.

Your passport, any visa requirements, and biometric information will all be checked before you’re granted entry.  Once you’ve successfully cleared immigration, you’ll officially be in China.

While border crossings can sometimes feel stressful, we found the Lao Cai–Hekou crossing to be efficient and relatively easy to navigate, making it one of the simplest overland routes between Vietnam and China.

What Documents Do You Need to cross from Vietnam to China?

Before traveling from Vietnam to China via the Lao Cai–Hekou border crossing, make sure you have all the required travel documents. Arriving at the border without the correct paperwork can result in delays or even being refused entry.

China Visa Requirements

While there has been an increase in the number of countries that now have visa-free travel (for a period of time) to China, some travelers will need a valid Chinese visa before arriving at the border. 

British Passport holders get 30 days visa-free travel now (yay!), and so do most European passport holders.

If you’re not subject to visa-free travel, then there is no visa on arrival.  You need to get it at a Chinese embassy or consulate.  You can check the requirements and details here.

Passport Requirements

Your passport should have at least six months of validity remaining from the date of entry into China.  Our current British passports were renewed during the time when the British Passport Office was renewing them ahead of time, and so they look as though they’re valid for more than 10 years (they’re not), and they did cause some consternation at the Chinese border in May 2026.  Explanations take a long time when someone else has to translate for you.  We’ve never had issues with them in any other country.  They let us in, though!

Arrival Cards and Immigration Procedures

China is rolling out a digital arrivals card – yay, no more paper. 

You NEED to do this ahead of time, and the link is here https://s.nia.gov.cn/ArrivalCardFillingPC/entry-registation-home

If you haven’t done this, you can do it when you get to the Chinese border.  Once you get across the bridge, you’ll see Chinese signs with QR codes.  You can scan them and get the digital arrival card.  If you haven’t completed the arrival form, then you will be sent back to do it.

The arrivals form asks for some details of your onward travel plans and destinations.

You’ll need to select the province first, and then the city or town. 

When you get to the immigration official, you may also be asked basic questions about your travel plans, accommodation, or onward transportation arrangements.

Make sure any answers that you give match what’s on your digital arrivals form!

Having copies of hotel reservations, train tickets, or travel itineraries readily available can help speed up the process if requested.  There’s no requirement for onward travel for China, but it helps to have an answer easily to hand for these simple questions.

If you had to apply for a physical visa for China, then you would have needed to submit your itinerary and hotel details. Note that they do NOT expect you to have all of that when you enter, nor do you need to stick to it.

Lines at the Chinese Border

There will be lines at the Chinese border.  Lines with Chinese Nationals in are likely to move more quickly, so if you have a choice, pick a line with fewer Western or Vietnamese nationals in.

Money, ATMs, and Mobile Data at Hekou

Cash is still useful here, but China is now massively digital-first, especially with payments (although it is still a legal requirement that you can use cash to pay, you are likely to struggle with people finding change for you!)  So this section is all about getting you set up so you’re not stuck at a shop counter, unable to pay, or trying to find an ATM at the last minute.

Exchanging Vietnamese Dong and Chinese Yuan

As you approach the immigration building in Lao Cai, you’ll find people willing to change any leftover VND for Chinese Yuan.  The same will happen on the Chinese side, once you’ve gone through immigration. 

Sometimes (i.e., most times) it’s just easier to eat any bad rate you get and move on.  You do NOT need to worry about having too much cash when you’re traveling in China in 2026 and beyond; they are very heavily into digital payments.  And that means that you will want to download and set up Alipay and WeChat/WePay.  Preferably, before you get to China.  There’s more on what you should do before you get to China in my guide here.

ATMs in Hekou

If you do want some cash, or more than you’ve changed your excess Vietnamese Dong for, then there are ATMs in Hekou.  However, not every ATM accepts foreign cards.  The best options for getting cash from an ATM in China with a foreign card are

  • Bank of China
  • Industrial and Commercial Bank of China (ICBC)

SIM Cards and eSIMs for China

Mobile and Internet connectivity in China works very differently compared to Vietnam. If you’re going to rely on hotel WiFi and not use mobile data, then you won’t easily be able to use Didi, the ride-hailing app (which is an amazing app), and you’ll struggle to use WeChat, WePay, and Alipay, which, in 2026, I view as essential for a trip to China.

Additionally, most Western apps like Google Maps, WhatsApp, Instagram, and Gmail are restricted without a VPN, or an eSIM that uses a server OUTSIDE of mainland China. VPNs in China are now somewhat quirky and don’t work as well as they used to.  The only VPNs that we found worked consistently in 2026 in China were HideMe VPN and Proton VPN.  My usual go-tos of NordVPN and ExpressVPN just plain didn’t work in China.

So having a working data plan is essential for navigation and translation apps.

You’ve got two options:  I’ll start with what makes the most sense.

  • eSIM (recommended if your phone supports it)
    This is the easiest option. You can activate it before you even cross the border, which means you arrive in China already connected.  Generally speaking, for this part of the country, the eSIM from China Mobile has the best coverage.  The eSIM from Trip.com is generally considered to be the best; you can get it here. (There are two options, a 3Gb a day one – after which you still get data, but it’s super slow, and a 10Gb a day one.  Both options allow you to hotspot and share the connection.  In our recent trip to China, we hit 3Gb only one day, and we were out ALL day and a lot of the night that day. Get an eSIM for China here.

The eSIM from China Mobile (this link) doesn’t need you to use a VPN to spoof your location.  It connects to servers in either Singapore or Hong Kong and lets you use all your Google Services, Facebook, and the like.  I would generally assume that all your content IS being tracked, though, and so you should probably fire up a VPN as well if you’re doing anything with sensitive data (like paying for things, or booking things with a credit card.

  • Local SIM card in Hekou
    You can buy a Chinese SIM card at official telecom shops. You’ll need your passport for registration, and staff usually help with setup.  However, if you’re planning onward travel on the same day, then you’ll need to factor in the time taken for this.  And it could take upwards of an hour, once you get to the store.  You should use Amap.com to find the store that you want.  Download the app BEFORE you get to China, the English language version is pretty good and worked well enough for us for a month in China in 2026.

The main providers of SIM cards are:

  • China Mobile
  • China Unicom
  • China Telecom

Onward Transport from Hekou

As I mentioned, most people coming across this border are heading from Hekou to Kunming, but here are some basics on onward transport.

A heads up:  While the ride-hailing app is both fabulous and a great app to use for transport in China is does NOT work in Hekou.  So you’ll need to use “traditional” taxis here in Hekou.  Make sure you agree on a price BEFORE you get in.

Aim for paying 20 CNY to go from the border to Hekou North Railway Station, where the fast trains go from.

Hekou to Kunming

It’s about 400 kilometers (248 miles) from Hekou to Kunming.  The easiest way to get there is by train, but you can also take a bus or get a transfer.  If you are taking the train, then you need to get to the Hekou North train station.  It’s about 15 minutes by car from the border.  A taxi will cost you around 20 CNY to get there. 

Hekou to Yuanyang

The second most popular place to head to from Hekou is Yuanyang for the rice fields.  I’ve written about going from Hekou to Yuanyang here.

Where to Stay in Hekou

If you’re planning on spending the night, or need to because you can’t make a bus or train connection, then there’s a reasonable selection of places to stay here.  Compared to Vietnam, you’ll find a lot less English spoken here.  Trip.com tends to be the best option for hotels in China.

Practical Tips for Crossing the Vietnam-China Border

The Lao Cai–Hekou crossing is generally smooth, but it’s still a real international border with rules, queues, and a few quirks that can catch you out.

  • Arrive Early:  If you’ve got onward travel planned, then getting here early is essential. 
  • Download Offline Maps:  Once you cross into China, your usual navigation apps may not work as expected.  Do yourself a favor and get an eSIM ahead of time.  Trip has a great set of options.
  • Download and Set up Payment Apps for China:  Mobile payments are key for China in 2026.  Alipay and WePay/WeChat are essential.

Our Lao Cai to Hekou Border Crossing Experience

We left Sapa at 09:30.  We stayed in the top part of the town for our last night in Vietnam, at a hotel close to the Church, which is where the buses leave for Lao Cai.  We headed to the Church at 09:15 to catch the 09:30 tourist bus to Lao Cai, which cost 28k VND in 2014. 

From the Lao Cai train station (Ga Lao Cai), we planned to catch an Xe Om (motorbike taxi) each for 20k VND to the China-Vietnam border. Alternatively, we could walk the remaining 2km in about 40 minutes. You can also take the Lao Cai to Sapa bus in the opposite direction. You’ll find it going from the Lao Cai train station to Sapa (there are also many minivan shuttles that will cost about the same).

However, our plan didn’t come to pass.  A minibus driver approached us and agreed to take us to Lao Cai for 30k. We further negotiated to get to the border for another 10k VND each. As the minibus was empty when we did this deal, we expected to be sitting around for the next hour while he drummed up trade. We were pleasantly surprised when we set off 10 minutes later, as he had promised, even though we weren’t full.

He operates by setting off a few minutes ahead of the bus – so en route to Lao Cai, we picked up several more folks, who were also waiting for the bus.

We were dropped off just before the border, with a Vietnamese wave in the general direction of “China, China”. You can see on the map where we were dropped off in Lao Cai.

Vietnamese Immigration at Lao Cai:  The entrance to Vietnamese immigration is through the exit, because you are exiting Vietnam. It’s a simple process; you stand in a line and get your passport stamped.

Vietnamese Immigration at Lao Cai, Vietnam: There were four folks in front of us, all of whom looked like regular visitors, and we were the only Western tourists. We were through in less than 5 minutes. That included standing by the sensor that checks your body temperature. Most of the folks crossing here are locals, not tourists.

Chinese Immigration at Hekou, Yunnan, China: Then, it was a short walk across the Friendship Bridge over the river, and we were heading into the Hekou immigration building.

There was no one here apart from immigration staff.

Chinese Immigration Hekou

First of all, we had a stop at the quarantine section and a passport check. Then it’s onto a small station where your passport is scanned. At the time, they input the visa number and print entry/exit cards. 

There was no visa on arrival here then, so we signed our cards and headed to the immigration booth. This is all within a very small area.  Scanned our bags through the security, and we were out!

It took us 16 minutes; we’d arrived at 11:44 on a Saturday morning.

Frequently Asked Questions about the Lao Cai Hekou Border Crossing

This section pulls together the questions people actually search for before making the journey. Most confusion about crossing the border comes from timing, logistics, and onward travel.

Can you walk from Lao Cai to Hekou?

Yes, you can walk between the two border checkpoints.  It is a simple walk across the bridge.  The walking distance is short.  However, you still need to go through full exit and entry procedures at both borders, and transport may be needed depending on where you’re staying or continuing your journey.

Once you’ve gone through immigration and are in Hekou proper, then most onward travel (like the railway station or hotels) is better done by taxi or local transport.

How far is Sapa from the Chinese border?

Sapa is relatively close to the Lao Cai border crossing.  Travel time is usually around 40 minutes to one hour.  You can easily stay in Sapa and cross the border the same day.  Roads are winding, so timing can vary depending on weather and traffic conditions.

What are the Vietnam & China Border opening times

China is one hour ahead of Vietnam. Vietnamese immigration is open at 07:00 (that’s 08:00 Chinese time). Then you need to walk across a bridge to the Chinese immigration. Chinese immigration is open from 08:00 am until 23:00 (Chinese time).

How long does the border crossing take?

This is a “how long is a piece of string?” question.  It depends, is the answer.  On average, the full process takes around 1 to 3 hours, depending on queues and time of day.  The Vietnamese exit procedures are usually quick (30–60 minutes), and then your walk is really quick.  And the entry to China usually depends on how many people are in front of you.

Can foreigners cross from Vietnam to China at Hekou?

Yes, foreigners can cross at Hekou, provided you’ve got visa-free entry, a valid Chinese visa (or a permitted entry document, or a passport with sufficient validity.  This is not a restricted “locals only” checkpoint.

Can you travel from Sapa to Kunming in one day?

Technically, yes, but it’s not the most comfortable or reliable plan.  If you want to move on from Hekou on the same day, then make sure you have an early departure from Sapa, book a train on to Kunming that gives you enough leeway for a delay at the border.  If you’re in any way unsure, then get to the border as it opens.

Final Thoughts on Crossing from Vietnam to China at Lao Cai and Hekou

Crossing from Lao Cai to Hekou is one of the most practical overland routes between Vietnam and China, and once you understand the flow, it’s far less intimidating than it first appears.  The border closed for some considerable time during COVID, but it’s open again, and it’s an easy border crossing.  The key is simple: arrive prepared, allow time for both sides of the border, and plan your onward journey from Hekou in advance.
