 What to see & do


Covering 18 730 square km the geography of the Western Forest Complex ranges from lowlands to high mountains. From rugged Yen and Tao Dam mountains in the north, through other limestone mountains, valleys, lowlands and water reservoirs in the middle, down to slopes of the Tenaserrim mountain range, that extends further over the border to Myanmar. The area is packed with rivers, creeks, caves, cliffs, waterfalls and viewpoints. It is also an important watershed area for 6 of the 25 major river basins in Thailand.


Very hot summers, very humid rainy season and quite cold winters. This is a bit of generalization for such a extended area, but not too far being accurate. Of course it involves many exceptions. For example the hills protecting the Erawan National Park from the eastern monsoon result in a lower average rainfall while the Kaeng Krachan National Park has heavy rains resulting in its closure during the rainy season.

When to go? The most suitable time for travelling around the Western Forest Complex is the cool winter, but for seeing waterfalls at its full beauty the rainy season is much better as the water levels are high. On some places the highest temperatures can reach 40 C in April and May and the lowest 3 C in December.
