This 1,000 metre peak is home to some 53 bird species and is the source of the Chanthaburi river. Locals believe the streams to possess cleansing powers, and if visiting on a weekend you might follow Thai pilgrims as they trek to a Buddha footprint and meditation cave on the cool and often misty mountaintop. If you're taken with the Buddhist pilgrimage thing, make a detour to Wat Khao Sukim.
