The Natural hot spring Next on the second day of the itinerary was the Krabi natural hot spring located at Amphoe Khlong Thom, It was about 70 km from Ao Nang city center. The hot spring mineral waterfall comes down from the nearby mountain and there are many hollowed-out 'bathtubs' which are caused by the running water from the thermal springs. We were given 20 minutes and took a chance soaked in the hot spring.
