Khao Lak (Thai: เขาหลัก, pronounced [kʰǎw làk]) is a series of villages, now tourist-oriented, mainly in the Takua Pa District and partly in the Thai Mueang District of Phang Nga Province, Thailand.
The name "Khao Lak" literally translated means 'Main Mountain'. This was one of the peaks used by ancient sea farers as a landmark to guide them into the safe harbor at Thaplamu. Lak mountain is one of the main peaks in the hilly small mountainous region (maximum height 1,050 meters (3,440 ft) in Khao Lak-Lam Ru National Park.
The tiny village of Ban Khao Lak, the original beach, Hat Khao Lak, and the bay of Khao Lak (Ao Khao Lak) actually all lie in the Lam Kaen sub-district of Thai Mueang District.
