A Bit of History

Before we dive into the wonders of Khao Sam Roi Yot National Park, let’s take a brief walk down memory lane.

Established in 1966, it was Thailand’s first coastal national park.

The name “Khao Sam Roi Yot” translates to “Three Hundred Peaks,” which reflects the park’s striking topography.

It’s interesting to note that the park has been an essential site for both history and culture, with evidence of prehistoric human settlement and a rich history of Thai royalty.

Location: Where is Khao Sam Roi Yot?

You might be asking yourself, “Where on Earth is this magical place?” Well, Khao Sam Roi Yot National Park is situated along the Gulf of Thailand, approximately 280 kilometers south of Bangkok.

The park spans 98 square kilometers and is part of the Tenasserim Hills, a mountain range that stretches from Myanmar to the Malay Peninsula.

Geological Marvels

Limestone Mountains

One of the park’s most distinctive features is its awe-inspiring limestone mountains.

These massive geological formations are not only eye-catching, but they also hold a rich history that dates back millions of years.

You might be surprised to learn that these mountains are the remnants of ancient coral reefs that once thrived under the sea.

Over time, tectonic forces pushed them upwards, and voilà, the magnificent landscape we see today was formed.

Isn’t Mother Nature a true artist?

Caves and Caverns

As if limestone mountains weren’t enough, Khao Sam Roi Yot National Park also boasts an impressive network of caves and caverns.

These subterranean wonders have been carved by water over millions of years, creating a labyrinth of intricate passageways and chambers.

Calling all animal lovers! Khao Sam Roi Yot National Park is a paradise for wildlife enthusiasts. The park is home to over 300 species of birds, making it one of the most important bird-watching sites in Thailand.
