There is a large parking area here along with cafes and shops. There are some quite steep steps to climb, but once you have reached the top the panoramic views of Southern Phuket are stunning.
At the top there is a two-level view tower which provides eight photo maps, in both Thai and English, so this will tell you exactly what you are looking at.
Chalong Bay is to the south, Makham Bay and Cape Panwa are to the east, Phuket Town to the north and in the distance you can see Ko Nakkerd which is the home of the islands famous big Buddha.
