Rock Valley Hot Springs and Fish Spa
Nestled within the grounds of River Kwai Village Hotel in Sai Yok district, this outdoor spa complex centres on 15 distinct herbal mineral pools, each offering a different temperature ranging from ambient to around 38–40 degrees Celsius. Pools are themed with ingredients such as milk, wine, coffee, and various herbs, giving each soak a different character. A fish spa experience and mud facial treatments round out the wellness offerings, making it more than a straightforward hot spring visit. The setting is rural and open-air, accessed via a quiet trail road with signage to guide visitors. The atmosphere leans toward natural relaxation rather than polished luxury, with the variety of pools encouraging guests to move between different temperatures and experiences at their own pace. Additional massage and spa services are available on-site at extra cost, making it easy to extend a visit into a longer half-day wellness outing. Good to know: Entrance is priced at 650 baht per person based on recent visitor reports, covering access to the pools, with massage and additional treatments charged separately. Swimwear is essential, and bringing your own towel is advisable. The cooler months of November through February are the most comfortable time to visit, as the warm pools contrast pleasantly with cooler air temperatures. Since opening hours are not published online, it is worth contacting River Kwai Village Hotel directly before making the trip to confirm current availability and session times.

Visitor Reviews
It was a super experience! There are 15 baths with milk, wine, and coffee of different temperatures. It's just magical! the entrance fee is 650 baht, you can get a massage for an additional price. They give you bathing suits, you can't wear your own swimsuit.
A very well designed spa with 15 different kinds of pool water (2 are at normal temp while rest are from 38 to 40 degrees) Access to it is via a rural trail road and signages are there to guide. Plenty of parking too. Once you enter, you can choose the package or simply entrance fee for 2hrs usage at 650baht per pax. You cannot use ur own swimwear but only theirs. Lockers r provided upon checking in and a small bottle of water is offered to you The varieties as said, are there for you to enjoy but the truth to be told, not much of a difference. Coffee pool had a very very slight coffee smell to it if you sniff it hard while the milk spa pool do not really look norishing to the skin. Nevertheless, it is a good spa overall and one of its kind within this area. Highly recommended!
This place is a must-visit! They offer 15 different herbal pool spas with an entrance fee of 650 baht, along with a variety of additional massage and spa services available for an extra charge. There are two ways to access the area: by boat or via a local road, which, though unpaved, is still accessible. I highly recommend coming by car to ensure you have plenty of time to relax and enjoy your visit. The facilities are very clean, and the service is excellent!

Tips for Visiting Activities & Tours
Vet Elephant Sanctuaries
Only visit sanctuaries that prohibit riding, use no chains or bullhooks, and let elephants roam freely. Elephant Nature Park in Chiang Mai set the standard. If a place offers painting shows or circus tricks, walk away.
Book Through Klook or GetYourGuide
These platforms offer instant confirmation, free cancellation on most activities, and prices that are often lower than walk-up rates. Compare with local agencies for multi-day trips where negotiation might save more.
Do Outdoor Activities in the Morning
Heat and humidity peak from noon to 3 PM. Schedule jungle treks, cycling tours, and outdoor cooking classes for early morning. Water activities are more flexible since you're in and out of the sea.
