Semenggoh is still reporting as it being available, but do let me know if that’s not the case.

It’s much harder to get a Grab back, if you’re taking one on the way out, its best to try and do a deal for a return journey, they’re much less likely to want to come out and get you for the return, as they are unlikely to get a fare on the way out at that time.

Thanks Steve, I’ll update the details.

Visiting hours are 8am-10am and 2pm-4pm. Feeding hours aren’t fixed anymore – they’ll feed the orangutans if they turn up earlier.
Note: Only vehicles belonging to Park staff, Park contractors and visitors on official capacities/visiting dignitaries (Diplomatic Corps, police, ambulance) are allowed in the park. All other vehicles must be parked outside – including taxis, tour buses and private vehicles. Visitors can then walk (20-30mins), cycle (10-15mins) or pay for an electric buggy (5mins) ride to the feeding platforms.

K6 can still be taken to get to Semenggoh but the driver has to be informed. K6 will however not return to pick you up. Semenggoh is not part of the official route for the K6 bus anymore.
The new 103 electric bus now does the Semenggoh route. Journey takes 1.5-2hrs each way due to its indirect route but the service is free. The 103 leaves Semenggoh at 8am, 10am, 12pm, 2pm and 4pm sharp. If want to catch this bus, you’ll have to wait till the next leaving time and you have to leave the feeding platform early. Taxi return trips from the city costs 100-150 ($23-34), ehailing services (Grab/AirAsia Ride) 25-35 ($6-8) each way. Most ehailing drivers would agree to wait until you come out for a token fee/tip ≈ 15-30 ($3.5-7)
