The pool and the water
There are two outlets. The main pool is a natural pool with no concrete lining. It is shallow, and a 2016 guide describes chairs placed in the water so you can sit and soak your feet up to the calves. A small concrete well is built over fissures in the ground behind it. A 2019 Universiti Kebangsaan Malaysia (UKM) study measured 43.5°C in the main pool and 46.1°C in the well, close to the 45°C recorded in 2013 and 2015. The bubbling spots at the source are hotter, so keep hands and feet away.
The water is neutral (pH 6.8 to 7.3) with about 31 mg/L of silicon. Iron and calcium were higher here and at Sungai Lalang than at the springs further up the valley, though both are still low. Sulphur was not tested. The water can look green, and one visitor reported algae in the pool. Tourism Selangor groups Sungai Serai with the Batu 16, MPKK Dusun Tua and IKTBN springs as geosite G16 of the Gombak-Hulu Langat geopark; Dusun Tua Hot Spring at Batu 16, about 7 km up the valley, has hotter water and free bucket bathing.
Facilities
Buckets, chairs, a toilet and a car park, according to the UKM study. Visitors on Petit Go say the site was revamped after the 2021 floods, with a bigger car park and a concrete sitting platform. One reviewer notes the platform steps are high with no railings, which is hard going for older visitors.
Fees, hours and status
The UKM study and several reviews give RM2 entry. Petit Go's listing and a 2020 guide give RM1. Parking is RM1. Hours also differ by source: 8am–7pm (Petit Go) and 8am–10pm (2020 guide). There is no website or phone line.
We found no recent visitor report that names the old pool on its own. Google Maps has no listing for it: searches at this spot return Serai Bamboo Hot Spring, mapped about 20 m away. Serai Bamboo reviews from September and October 2026 give entry as RM7 for Malaysians, and an October 2026 reviewer describes a single shallow pool, about 60 cm deep, with hot water rising from a few wells, a sandy bottom and a platform in the middle. That matches older descriptions of this pool, so it may now be run as part of Serai Bamboo, but we could not confirm it. A 2024 guide also listed "Sungai Serai hot spring" with Serai Bamboo's address and phone number and hours of 7am–10pm. If you arrive and find only Serai Bamboo, expect to pay its rate of RM6 to RM7.
Setting
The pool is right beside the main road, so it is noisy, and one reviewer left without getting in because of the traffic. A 2020 guide warns that the area is dark at night.
Getting there
From Kuala Lumpur, take Jalan Hulu Langat (B52) towards Hulu Langat town. The pool is on the main road in Kampung Sungai Serai, around the Batu 11 to 12 marker and close to Masjid Ehsan. Parking is on site for RM1. Public transport to Hulu Langat is limited, so drive or take an e-hailing ride. Dusun Tua is further along the same road at Batu 16.
Before you go
- Bring small notes and coins for entry and parking.
- Keep away from the bubbling spots at the source. They are hotter than the 43–46°C pool.
- Wear sandals with grip. The sitting platform has high steps and no railings, so older visitors may need a hand.
- Bring a towel and a change of clothes. There is a toilet but no proper changing room or showers.
- If you only find Serai Bamboo at Batu 12, that is the newer paid site. Ask staff whether the old village pool is still open next door.
Questions people ask
How hot is Sungai Serai Hot Spring?
A 2019 UKM study measured 43.5°C in the main pool and 46.1°C in the small well behind it. Earlier studies recorded about 45°C.
How much is the entry fee?
RM1 or RM2 per person depending on the source, plus RM1 for parking. Pay in cash.
Can you swim in it?
No. The pool is shallow, so people sit on chairs or the edge to soak their legs, or bathe with buckets.
Is Sungai Serai Hot Spring the same as Serai Bamboo Hot Spring?
They share the Sungai Serai spring field and the Batu 12 address, and Google Maps now lists only Serai Bamboo at this spot. Serai Bamboo is a newer business charging RM6 to RM7 with private rooms and food stalls. An October 2026 review of it describes a single shallow pool with a platform in the middle, much like the old one, but we could not confirm whether the old RM2 pool still runs separately.
Is it open at night?
Sources disagree: 8am–7pm in one listing, 8am–10pm in a 2020 guide. The area is dark at night, so plan to go in daylight.
