Khao Sahm Muk, which translates as ‘Three Porches Mountain’, is a small coastal mountain in Chonburi and features on the provincial coat of arms (fig.).

It is located on a spit of land, roughly in between Bang Saen Beach (fig.) and Ang Sila fishing village and offers a panoramic view of the area.

This seashore hillock is occupied by large groups of Crab-eating Macaques, that live here in the wild. They often obstruct traffic and jump on cars visiting their habitat.
