Located in the northern part of Phuket, Khao Phra Thaeo National Park is the island's last significant virgin rainforest. You can spend a morning taking a leisurely walk up by Tonsai Waterfall. There's also an 8-km trail right through the park from Bang Pae Waterfall to Ton Sai.

It's a good idea to hire a guide to explore the national park. Most of the forest's wildlife tends to stay out of sight, but your guide should be able to point out the telltale sounds of all sorts of animals. A small museum and information centre is located near the bottom of the waterfall.
