Khao Lak (Thai: เขาหลัก) is a resort beach in Thailand, located 100 km north of Phuket in Takua Pa district, Phang Nga province and popular as a departure point for liveaboard scuba diving trips. The coast line here has a west-facing, sandy beach with tropical forest and rubber plantations on the hill slopes beyond the sand. A road runs roughly parallel with the beach and the town has grown up as a ribbon development of shops and dwellings, with tourist hotels between the road and the beach.
Khao Lak was the area of Thailand hardest hit by the tsunami resulting from the 2004 Indian Ocean earthquake. Many people died including many foreign tourists. The final death toll was over 4000.
