Kerling Hot Spring

The pool

There is one rectangular pool with stone and concrete walls and a safety barrier around it. Tourism Selangor says the spring was upgraded in stages into a shallow square pool. A UiTM study published in 2013 measured the water at 40.0°C, which the authors classed as "thermal" rather than hyperthermal, and a 1997 national survey listed Kerling at 45°C. Malaysia Traveller found it hot but bearable, and a June 2026 reviewer said it is mild enough for all ages. If you want a long, very hot soak, Selayang or Hulu Yam run hotter.

Reports on cleanliness vary. A 2021 Tripadvisor reviewer called the pool clean; a February 2024 reviewer said the grounds were well kept but the hot pool was very dirty. In November 2024, UPSI students and volunteers collected 86.25 kg of rubbish around the site, and a July 2026 visitor found a dead bird in the hot pool. Check the water before you get in.

Water chemistry

The UiTM study is the only analysis we found. It recorded pH 7.1, total dissolved solids of 312 mg/L, about 60 mg/L sodium, 21 mg/L potassium, 15 mg/L calcium, 12 mg/L sulphur, 12 mg/L chloride and very little sulphate (0.3 mg/L). That is mildly mineralised water: fine for bathing, not for drinking.

The river and flash floods

A shallow, fast-flowing river runs beside the pool, with a bridge across to the rest area and concrete steps down the bank. On Malaysia Traveller's visit most people were in the river rather than the hot pool. September 2026 reviewers found the river cold and full of small stones, so wear water shoes. A June 2026 camper says a short walk upstream leads to a low waterfall over big boulders.

The river can rise fast. At about 3am on 15 September 2025, a public holiday during the school break, a flash flood (kepala air) trapped around 400 people camping and picnicking here. Firefighters from Kuala Kubu Bharu were called out, people moved to higher ground, and all were reported safe.

Facilities and camping

There is parking, toilets and a changing room, a surau, picnic gazebos, a BBQ area, a playground and landscaped gardens. A June 2026 visitor found stalls selling ice, ABC, laksa and corn; another that month found the surau locked and had to ask staff for the key.

Nothing is free any more. A September 2026 reviewer paid RM5 for parking, RM0.50 for the toilet, RM15 for a gazebo and RM10 for a hut with stone seats; tubing also costs extra. A June 2026 camper paid RM30 per tent per night, charged per tent whatever its size, at the counter beside the toilets. Pay before you use anything. There are no rubbish bins, so take your rubbish home, and the camper notes the forest department watches the area: no fires directly on the ground.

In November 2024, MPHS told the state assembly that it planned to upgrade the playground, after a question noting that many public facilities at the site were damaged. We found no report that the work has been done.

Council by-laws posted at the park ban dogs, hawkers, cycling and motorcycles inside, littering, open burning, picking plants and vandalism.

When to go

Google Maps lists the park as open daily 8am–6pm, and a September 2026 visitor saw an 8am opening time posted at the site, though no staff had turned up by 9.30am. Malaysia Traveller (undated) lists pool maintenance at 8.30–9.30am daily and 2.30–3.30pm on Saturdays and Sundays. The park is busiest on weekends and during school and public holidays.

Google reviews from May to October 2026 show the park open and busy. Several 2026 reviewers complained about rude counter staff; others found the toilets clean and called it good for children.
