Cheow Lan Lake
A vast lake of limestone mountains, floating resorts and rainforest routes in the heart of Khao Sok National Park.
CHEOW LAN LAKE AT A GLANCE
A lake shaped by mountains, forest and water.
Cheow Lan Lake stretches deep into Khao Sok National Park, with long waterways running between limestone mountains and rainforest.
From Ratchaprapha Pier, traditional longtail boats travel into different parts of the lake — some reached within an hour, others requiring a much longer journey into the interior.
This is why where you stay and which route you choose can completely change your experience of Cheow Lan Lake.

EXPLORING CHEOW LAN LAKE
The Journey Starts at the Pier
Almost every journey onto Cheow Lan Lake begins at Ratchaprapha Pier. From here, you leave the road behind and continue by traditional longtail boat.
There is no single route around the lake. Boats travel through different waterways depending on where you are staying and what you want to see. A day trip may focus on limestone scenery, Khao Sam Kler and a cave or short walk, while an overnight stay gives you time to travel farther, kayak from your floating resort and head out again early the next morning.
Some of the most interesting parts of Cheow Lan Lake are far from the pier. Choosing the right route matters just as much as deciding how long to stay.

STAY ON CHEOW LAN LAKE
Where You Stay Shapes the Journey
Floating resorts are spread across different parts of Cheow Lan Lake, and location matters. Some are closer to Ratchaprapha Pier, while others require a longer boat journey into the lake.
Your choice of resort can affect more than the room itself. It can influence the scenery around you, the activities that fit naturally into your stay, and how much time is spent travelling by boat.
Choosing by room alone can be misleading. A beautiful resort may not be in the best location for the route you have in mind, so we normally look at the stay and the itinerary together.
When Is the Best Time to Visit Cheow Lan Lake?
There is no single itinerary that works for everyone.
For the most reliable dry weather, January to March is usually the easiest period to plan around. Trails are generally easier, boat trips are less likely to be affected by heavy rain, and these months fall within the main visitor season.
But that does not automatically make them the best months for every traveler.
From around May into November, rainfall increases and the forest becomes noticeably greener. Waterfalls carry more water, clouds and mist are more common around the limestone mountains, and rain can completely change the character of the lake. The Tourism Authority of Thailand specifically highlights Ratchaprapha and Khao Sok as worthwhile rainy-season destinations because of these conditions.
The trade-off is less predictable weather. Heavy rainfall can affect hiking routes and cave access, and some activities may need to be changed for safety.
Our local view: If weather is your priority, come between January and March. If you prefer greener forest, waterfalls and mist and do not mind occasional rain, the green season can be just as rewarding.
Best Time to Stay at a Floating Resort
Floating resorts operate across different parts of Cheow Lan Lake, and the experience changes with the season.
December–January
Generally comfortable conditions, but strong demand. Reserve early.
February–April
Drier weather but hotter afternoons and nights. Air conditioning becomes more valuable.
May–June
Greener surroundings and generally fewer visitors, with increasing chance of rain.
July–August
Beautiful green-season scenery but stronger international holiday demand than many people expect.
September–October
Very green and often quieter, but flexibility with outdoor activities is important.
November
A transition month. Conditions can vary from wet periods to increasingly dry weather.
The choice of resort can matter as much as the month. Some floating resorts are roughly 35–45 minutes from the pier, while more remote properties may require around an hour or longer by longtail boat.
FIRST, KNOW WHERE YOU NEED TO GO
Cheow Lan Lake and Khao Sok village are in the same national park area, but they are not the same destination.
Most Cheow Lan Lake tours and floating resort stays begin at Ratchaprapha Pier, near Ban Ta Khun. Khao Sok village and the national park headquarters are on the western side of the park, about an hour away by road.
If you are booking your own transport, always check the meeting point on your tour confirmation. For a lake trip, you will usually need to travel to Ratchaprapha Pier, not Khao Sok village.
