A visit to Krabi natural hot spring is a must. There are many hollowed-out 'bathtubs' which are caused by the running water from the thermal springs. You can relax in one of the many natural hollows in the creek and watch the water gently cascade into the cool pools. Enjoy your own natural "hot-tub jacuzzi" filled with running spring water at a pleasant of 35 degree celcius-40 degree celcius.
