Khao Sok National Park Facts

Khao Sok National Park has an exciting history behind it — both natural and human. Let’s start with the natural.

Khao Sok natural history

Over 220 million years ago, limestone deposits began to form as marine life created an expansive coral reef that stretched from China to Borneo. For those of you who are good with geography and math, that’s about five times the size of the Great Barrier Reef.

It also explains why the landscape looked so similar to Ha Long Bay—they were both parts of the same giant coral reef.

This coral reef continued to grow as it teemed with life, and the limestone stayed buried deep under the sea.

That is until the Indian tectonic plate crashed into the Eurasian plate. As we know, this formed the Himalayas and caused massive shifts in the geography of this area of the world.

What is lesser-known is that caused these, along with the other limestone karst found throughout Southeast Asia, to shoot upward and above sea level. 

Now that they were exposed to the elements, the rain slowly eroded them over millions of years, resulting in the beautiful formations we see today.

Khao Sok human history

The human history surrounding Khao Sok National Park is slightly less…beautiful.

The first reports of people inhabiting the area date back to the 1800s. The Burmese and Thais were consistently at war, often with the Burmese attacking the coastal areas. Residents of the area, having no means to defend themselves, would retreat to the jungle.

People would continue to live in the area over the next 200 years, people would continue to live in the area. That was until 1944.

During this time, a deadly epidemic swept through the area and killed many of the population. Those who survived left. It was abandoned for years and donned the name “Corpse Village” or “Baan Sop” in Thai.

This led to a taboo-like feeling for Thai people and wanting to live in the area. Therefore, it was empty when Thai students and communist insurgent groups occupied the caves in the area to defend it against the Thai army, loggers, miners, and hunters.

For seven years, these groups continued to defend it and are a significant reason it still stands today. Had it not been for these groups, the area may have been forested and mined until nothing was left.

In the early 1980s, the Electricity Generating Authority of Thailand (EGAT) became interested in the area. 

Thailand’s National Park Division’s research found Khao Sok to be the largest watershed in the south. It didn’t hurt that it teems with various plants and animals worth protecting.

So, in December 1980, Khao Sok National Park became Thailand’s 22nd national park.

And this leads us to today.

A trip through Khao Sok National Park in Thailand provides you with vast limestone karst formations, extensive caves that house bats and other animals, and a thick forest filled with incredible plants and wildlife.

A quick note: you should visit during the dry season or on the shoulders of dry season (November-May). Once the rainy season sets in, visiting Khao Sok could be dangerous with strong storms and flash floods.

The Sok river runs through the center of the park and could flood quickly with one of the frequent storms that pass during the rainy season.

Are felines more your thing? You can find tigers, leopards, and the clouded leopard in the park.

Various species of monkeys can be heard calling out and swinging in the trees overhead as you walk the trails that run through the park.

And herbivores — like the mouse deer, tapir, gaur, and even elephants — roam the park, snacking on its fresh vegetation.

Put simply, there’s no shortage of wildlife to catch in their natural environment here.

And we haven’t even gotten to the gem in the middle of Khao Sok National Park — Cheow Lan Lake.

Boating on Cheow Lan Lake in Khao Sok National Park is a top activity.

Khao Sok Lake National Park

EGAT built a dam that flooded the area. The result? A gorgeous stretch of water covers 102 mi² of the 459 mi² park.

To enjoy the park fully, visitors can take a long-tail boat ride for an easy day tour. 

This includes a lake tour, a visit to various caves, and lunch on one of the floating rafts. If there’s time, jump in the lake waters to cool yourself off, or kayak if you prefer.

If that isn’t enough for you and you want more of the park, you can book an overnight stay in one of the floating bungalows. You can choose a simple bamboo raft house or a deluxe bungalow if you’re looking for more luxury.

Wake up early in the morning to birds chirping and limestone mountains beginning to show themselves in the morning sun.
