In the South of Krabi in the province of Klong Thom District are nature’s own hot-tub jazuzzis known as น้ำตกร้อน (naam tok rawn) in Thai. The water here comes from thermal springs originating deep underground in volcanic chambers. Located in the jungle, this site features naturally hollowed-out ‘bathtubs’ in the smooth stone, filled to the brim with fresh running spring water at a pleasant 35 – 40 degrees Celsius. After a soak, take a refreshing dip in the cool river below.
Water from the hot springs flows through the rocks into larger man- bathing pools on the same site and basic changing facilities are now available for visitors.
The mineral salts contained in the hot spring water are said to ease a number of ailments, including rheumatism, sciatica and skin complaints.
A visit to the Hot Springs would not be complete without a trip to the nearby Emerald Pool (สระมรกต or Sa Morakot in Thai), this is an astonishingly hued and large natural pool that is filled with pure spring water.
The pool is reached via a network of trails through the Khao Nor Chu Chi forest (the longest of which is 1.2km – no climbing required), which offer a glimpse into a unique aquatic ecosystem, fed by the area’s abundant spring water. You’ll pass by a series of clear mini-pools, waterfalls and streams, plus hundreds of species of tropical trees and plants.
The other “must-see” site in the reserve is the brightly coloured ‘Blue Pool’, located some 600m further upstream from the Emerald Pool.
This area is also popular with birders as the forest is home to many rare species, including the endangered Gurney’s Pitta. A full day could easily be spent here as there are many other trails around the site.
