Sungai Lalang Hot Spring is a privately owned hot spring on Jalan Sungai Lalang in Semenyih. The site was once an illegal dumping ground. It has since been cleaned up into a large soaking pool where spring water bubbles up through a sandy bottom, plus a smaller second pool, showers and a car park.

Come for a cheap sit-down soak in the early morning or evening: it runs two sessions, 6am–10am and 4pm–10pm, and closes in between.

The pools

There are two pools. In the large one, you can watch bubbles rising through the sand where the spring comes up. Reports on the small pool disagree. A July 2026 SAYS round-up calls it cooler and suited to children, while a 2024 guide says it is the hotter of the two. Test the water with your hand before letting kids in. A concrete well behind the main pool also holds spring water.

How hot

In 2019 a UKM team measured 51.5 to 51.8°C at its two sampling points here. Earlier studies recorded 36.7°C (2013) and 41°C (2015), and the 2019 authors note that results varied with weather and conditions on the day. Beauty Insider (2024) describes the large pool as moderately warm and suitable for most people. A reviewer who came at 8am on a Saturday in October 2026 judged the main pool a little over 40°C, hotter near the bubbling source, and noticed a faint sulphur smell; about 20 people were soaking at the time.

The water

The water is neutral (pH 7.3 to 7.4), with about 28 mg/L of silicon. Iron, calcium and manganese were higher here than at most other Hulu Langat springs, though still low in absolute terms. Sulphur was not tested. The UKM authors listed Sungai Lalang, along with Sungai Serai and Batu 16, as having potential for health tourism, and noted that it has been classed as a geological feature site in Hulu Langat.

Facilities

There are toilets, showers that SAYS describes as clean, and plenty of parking. The owner also runs a small snack shop, and there are food and drink stalls nearby; an October 2026 visitor had coconut water after soaking. A September 2026 reviewer found the pool and the toilets used for changing clean, and said the pool gets strong sun, so the early morning and evening sessions are the comfortable ones. The Google listing shows wheelchair-accessible parking and entrance.

Hours and fees

The split hours are the thing to plan around. The owner's Google listing (October 2026) gives 6am–10am and 4pm–10pm daily, the same as a 2024 guide; a July 2026 SAYS round-up gave 10.30am and 4.30pm instead. SAYS listed entry at RM5 per person, but reviewers in August and October 2026 paid RM6, one noting that was the rate for foreigners. Child prices are not published.

Getting there

The spring is on Jalan Sungai Lalang, on the Semenyih side of Hulu Langat district (postcode 43500). From Semenyih town, head north towards Sungai Lalang. The pool is marked on OpenStreetMap as Kolam Air Panas Sungai Lalang (GPS 3.0423, 101.8725). Parking is plentiful. There is no practical public transport, so drive or take an e-hailing ride.

Before you go

  • Check the clock before you set off. It is closed from late morning to late afternoon.
  • The morning session ends at 10am on the Google listing (10.30am in a July 2026 round-up), so arrive early enough for a proper soak.
  • Feel the small pool's temperature before letting children in. Reports disagree on whether it is the cooler or the hotter pool.
  • Bring cash for entry and for the snack stalls.
  • In the big pool, look for bubbles rising through the sand. That is where the spring water comes up.
