Khao Rai Mountain
Khao Rai is the tallest mountain on the island of Ko Pha Ngan. To get to the top you will follow a dirt road until eventually this turns into jungle trail. There are many roots along the trail and this makes it very technical. At the top, you have an amazing view to the north of the island and can see Ko Pha Ngan's neighbouring island, the smaller Ko Tao.
