Khao Sok National Park

National Park in Khao Sok National Park

Khao Sok National Park is close to the Andaman Sea, and possesses the classic Andaman topography: signature fern-covered limestone cliffs that shoot straight up into the air like crocodile teeth. It's also home to a number of gorgeous waterfalls that gush during the rainy season (May to October). You'll need a guide (per day 1200B) to access them; this can be arranged at the national park headquarters.
