Khao Sok National Park (Thai: เขาสก, pronounced [kʰǎw sòk]) is in Surat Thani Province, Thailand.

[citation needed] Heavy rainfall and falling leaves led to the erosion of the limestone rocks and created the significant karst formations seen today.

Thus, it's dangerous to simply cut a tree in the jungle because it can pull connected liana vines with it creating a cascade of damage.

There have been historical records up until a few decades back but there is no trail cam evidence that they still exist in Khao Sok or within the surrounding forest complex.

[3] Khao Sok on the part of the Ratchaprapha Dam is also the last natural habitat in Thailand of the Asian arowana, an endangered living fossil fish.

Humidity and warm temperature provide the optimal environment for a rich eco-system in this tropical rain forest.

This area is estimated to be over 160 million years old, built through tectonic movements, climate changes, erosions and sediment accumulations.

[citation needed] Approximately 300 million years ago, shallow water and warm temperatures in this region led to the creation of a huge coral reef.

Estimated to be 5 times as big as the Great Barrier Reef in Australia, it originally stretched from China all the way to Borneo.

In the Burmese-Siamese War (1809-1812), the Burmese army invaded the western portion of the area, forcing the inhabitants to flee inland.

The dam provides electricity for the south, and the lake became a major holiday destination for Thai and foreign tourists alike.

Sightings of monkeys, tropical birds and insects are common, however its possible to find wild elephants, serow, tigers, and Malayan sun bears.
