Lamu. Lak Mountain is one of the main peaks in the hilly, mountainous region (maximum height 1,050 meters 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) all lie within the Lam Kaen Sub-district of Thai Mueang District. However, the name Khao Lak has now grown to enclose many other villages in the area, mostly on the northern side of the mountain in the Khuk Khak Sub-district of Takua Pa District.
