Than Bok Khorani National Park covering over 100 square kilometres is broken up into several different patches scattered mostly around the towns of Ao Luek, Bor Thor and Laem Sak in Krabi Province and located around 50 kilometres north of Krabi town. Ko Hong and several other small islands in Phang Nga Bay are also overseen by Than Bok Khorani, but these are much further south and more difficult to reach.
At the Visitor Centre just south of Ao Luek, a nature trail leads straight to the park’s namesake attraction: Than Bok Khorani Waterfall. Draped in long rattan leaves and bamboo groves, the roots of dectarocarp trees reach into a wide stream coloured a cloudy emerald by calcite deposits from the nearby mountains.
