Kathu is located in the middle of Phuket Island, between Patong to the west and Phuket town to the east. It also includes the tourist beach of Patong. It is largely a residential area with big mansions owned by affluent locals and expats. It is an ideal area for those who want to stay centrally with plenty of things to do nearby. The Kathu waterfall is the highest point in Phuket, about 540m above sea level.
