Immediately south of Hat Khao Lak, the vast 125-sq-km Khao Lak/Lam Ru National Park is a collage of sea cliffs, 1000m-high hills, beaches, estuaries, forested valleys and mangroves. Wildlife includes hornbills, drongos, tapirs, gibbons, monkeys and Asiatic black bears.
The visitors centre, just off Hwy 4 between the Km 56 and Km 57 markers, has little in the way of maps or printed information, but there’s a very nice open-air restaurant perched on a shady slope overlooking the sea. From the restaurant you can take a fairly easy 3km round-trip nature trail that heads along the cape and ends at often-deserted Hat Lek beach.
