The complete guide to Cheow Lan Lake

Escape to one of the oldest rainforests in the world, not far from Surat Thani and home to 5% of the world’s species – Khao Sok National Park. Deep in the succulent thickets of this 300 million year lowland jungle, known as the wettest spot in Thailand, you will be delighted to find Khao Sok’s emerald jewel – Cheow Lan Lake.

About Cheow Lan Lake

This magnificent man-made lake covers approximately 185 square kilometres. Emerging from the cool water are limestone karsts, traces of a coral reef system that once stretched from Borneo to China. These dramatic limestone formations, some of which reaching an impressive 960m, are dense with cycad palms that have thrived since the dinosaur-era and host a spectacular array of life.

Cheow Lan Lake - Khao Sok National Park

Cheow Lan Lake formed in 1982 by a shale-clay dam called Ratchaprabha. Since its tucked away in the thickets of Khao Sok National Park – an area that remains relatively untouched and protected. Therefor the environment thrives and teems with magical biodiversity. The scenic body of water stretches its klongs (Thai word for river or waterway) inland reaching out for the rocky ridges and crags.

Klongs (waterways) of Cheow Lan Lake

There are several klongs sprouting from Cheow Lan Lake. Klong Ka is the easiest to get to being the closest to Ratchaprabha pier. Highlights here include travelling past the mesmerising Gui Lin viewpoint boasting many of the jutting limestone karsts. As well as easy hikes on flat terrain, enveloped by mountains and tall lush grass. This is the home of Pra Kay Petch cave, also knows as Diamond cave, one of the best in the park with awesome stalactites and stalagmites, and many bats.

Cheow Lan Lake Guide

Klong Pey

Klong Pey is 2 hours from Ratchaprabha pier. Here you will find some of the best trekking along the trail to Nam Talu cave (January – April only). Journeys to this massive, almost 1km cave are often made at night when nocturnal life is aplenty. With a headlamp strapped to your brow, splash through waist-deep water in the cave keeping an eye out for nightly visitors like bats, spiders and crabs. The valley surrounding the cave has an interesting history as it was used as a sanctuary for foot soldiers and communists.

Klong Yee

The third waterway, Klong Yee is remote and secluded and falls within the wildlife sanctuary, along with its neighbour, Klong Wong. This means it features abundant animal life against a peaceful backdrop of water and jungle – ideal for kayak trips and nature safaris. Another highlight is a gorgeous waterfall hike (April to December) and a walk to the Krai Son viewpoint that overlooks a breathtaking valley.

Klong Saeng

Klong Saeng is Cheow Lan’s north-western waterway and was once Thailand’s largest river before the lake was made. It is the longest trip, nearly 3 hours by boat, but so worth it. This wildlife reserve requires special consent (and an extra fee). A park ranger will lead you into the natural riverine setting where you have a good chance of spotting wild elephants and deer.

Klong Mon

Klong Mon is distinguishable from its many elevated hills and valleys. This is a fantastic choice for bird-watching with its peaceful rocky outcrops. Often spotted here are Grey eagles and hornbills. There is a trail from Klong Mon to Klong Saeng but you need to notify the Khao Sok park ahead of the time as you need to be accompanied by a ranger.

Khao Sok Lake

Klong Mon is also an awesome spot if lure fishing is your sport! Get your adrenaline pumping and ask about snakehead fishing. Three types of snakehead are abundant in Khao Sok waters and the crowds of immersed trees make an excellent labyrinth for these predatory fish with their snake-like heads and sharp teeth. Other fish predominant in this area include jungle perch, mahseer and catfish. Cast-off from a long-tail boat while the sounds of the lake hum around you, a memorable catch for anyone who loves fishing.

Klong Long

Klong Long is the most popular and busiest klong due to the quick hike and raft ride to Coral cave (also known as Pakarang cave); boasting coral fossils over 10 000 years old. Also a 2.5 hour trek through deep jungle will lead you to the southern tip of the curve showcasing an impressive viewpoint.
