Topography
- Thailand's southern peninsular is in the direct path of east and west monsoons, and rain falls on the mountain ridges nearly all year round. The abundant rain gives rise to many beautiful streams and green and moist nature. Klong Phanom (in the south of Khao Sok national park across the highway 401) is going to be a national park. This park covering 410 square kilometers is in Phanom district of Surat Thani province.
- The high mountain range of Klong Phanom consists of many steep cliffs typical of the limestone mountains in this area. Fertile forests drape the mountains, and many streams flow beneath the towering greenery. Klong Phanom is a vital water source for surrounding communities and towns.

Tourist attractions
