Phuket's waterfalls are not the biggest in the country but they are interesting gathering places for those seeking a cool place for a dip or a picnic. There are two major falls, Ton Sai and Bang Pae and they are both located in Khao Praew Thaew National Park 22 kilometers north of Phuket Town. Phuket's last significant virgin rain forest is a designated national park located in the northern part of the island. Best visited in the monsoon season from May to October, the surrounding jungle is great for trekking through and there's also the worthy Gibbon Rehabilitation Project right by.
