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.

LOCATION
Different resorts sit in different areas of the lake.
BOAT JOURNEY
Travel time from Ratchaprapha Pier varies by resort.
EXPERIENCE
The right location depends on what you want to do during your 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.
FROM SURAT THANI TO CHEOW LAN LAKE
Surat Thani is the easiest transport hub for reaching Cheow Lan Lake. Travelers may arrive by flight, train or bus, but each arrival point is in a different location, so it is important to know exactly where your transfer starts.
FROM SURAT THANI AIRPORT
Surat Thani Airport is one of the most convenient arrival points for Cheow Lan Lake, especially if you are flying from Bangkok.
A private road transfer from the airport to the Ratchaprapha Pier area normally takes around 1–1.5 hours, depending on traffic and the exact meeting point.
If you are staying overnight on the lake, check your required pier arrival time before booking a flight. Floating resorts and private tours do not all depart at the same time, and arriving too late may mean that you cannot reach your resort as planned.
Practical advice: For an overnight lake stay, an early or mid-morning arrival at Surat Thani Airport gives you more flexibility than an afternoon flight.
PRIVATE TRANSFER
Surat Thani Airport → Ratchaprapha Pier
Private vehicle from ฿1,800
This booking is for the road transfer only.
FROM SURAT THANI TOWN
Surat Thani town is farther east than the airport and railway station.
The road journey to Ratchaprapha Pier is typically around 1.5 hours. Public vans may be available toward the Ratchaprapha Dam area, but schedules and drop-off points can change. Thailand's tourism authority also describes road connections from Surat Thani town toward Ratchaprapha Dam at around this travel time.
For travelers with luggage, children, a fixed boat departure or a specific floating-resort check-in time, a pre-arranged transfer is usually simpler because it can take you directly to the correct pier.
IMPORTANT: YOUR BOAT DOES NOT LEAVE FROM SURAT THANI
Your road journey ends at Ratchaprapha Pier. From there, you continue into Cheow Lan Lake by longtail boat.
The boat journey to your floating resort is separate from the road transfer and may take roughly
35 minutes to more than an hour, depending on the resort's location.
PRIVATE TRANSFER
Surat Thani Town→ Ratchaprapha Pier
Private vehicle from ฿2,200
This booking is for the road transfer only.
FROM SURAT THANI TRAIN STATION
Surat Thani Railway Station is actually located in Phun Phin, outside Surat Thani city.
From the station, allow roughly 1–1.5 hours by private vehicle to reach Ratchaprapha Pier, depending on road conditions.
Overnight trains from Bangkok are popular with travelers heading to Khao Sok and Cheow Lan Lake, but train arrival times can change. If your lake boat has a fixed departure time, leave a reasonable buffer between the scheduled train arrival and your pier check-in.
Practical advice: Do not arrange your boat departure too tightly around the published train arrival time.
FROM DON SAK PIER TO CHEOW LAN LAKE
Best for travelers arriving from Koh Samui, Koh Phangan or Koh Tao
Don Sak is an important connection point between the Gulf islands and Cheow Lan Lake. If you are travelling from Koh Samui, Koh Phangan or Koh Tao, you can arrive on the mainland and continue west by road toward Ratchaprapha Pier without travelling into Surat Thani town first.
This makes Don Sak → Cheow Lan Lake a practical route when combining the islands with an overnight stay on the lake.
From Don Sak to Ratchaprapha Pier
After arriving at Don Sak, continue by road directly to Ratchaprapha Pier.
Allow approximately 2–2.5 hours by private vehicle, depending on your ferry terminal, traffic and road conditions.
There is normally no reason to travel into Surat Thani town first if you have a private transfer waiting at the ferry terminal. Going directly from Don Sak toward Ban Ta Khun and Ratchaprapha Pier is the more practical route.
Coming from Koh Samui
Regular ferry services connect Koh Samui with Don Sak. For example, Seatran's current published service between Nathon and Don Sak takes approximately 1 hour 30 minutes.
If you plan to enter Cheow Lan Lake on the same day, choose an early ferry from Samui and check your floating resort's boat departure or check-in time before booking.
Do not calculate the journey using ferry time alone. You also need time to disembark, collect luggage, meet your driver and travel from Don Sak to Ratchaprapha Pier.
Coming from Koh Phangan
Koh Phangan also has ferry connections toward the Surat Thani mainland via Don Sak. Journey times depend on the operator and service; car-ferry services can take around 2.5 hours between Koh Phangan and Don Sak.
For a same-day connection to a floating resort, an early departure from Koh Phangan is preferable.
If the ferry reaches Don Sak later in the day, staying one night near Ratchaprapha Pier before entering the lake the following morning may be a better plan than trying to make a late boat connection.
Coming from Koh Tao
Koh Tao requires more careful planning because the sea journey is longer and routes vary by operator.
Some services connect Koh Tao → Koh Phangan → Koh Samui → Don Sak. A current 2026 Boonsiri service, for example, leaves Koh Tao at 08:00 and reaches Don Sak at 11:40.
That does not mean every Koh Tao ferry follows this route or timetable. Ferry schedules change, so travelers should check the actual mainland arrival point before arranging the road transfer.
For Koh Tao in particular, avoid booking a floating-resort boat based only on the scheduled ferry arrival. Allow enough time for the ferry connection and onward road journey.
Check Which Don Sak Pier You Are Arriving At
This is important.
Don Sak is not one single ferry terminal. Different operators use different piers in the Don Sak area, including Seatran and Raja Ferry terminals, with other passenger services using their own departure and arrival points.
When arranging a private transfer, send your operator:
Ferry company • Ferry number/time • Departure island • Scheduled arrival time
rather than simply saying “Don Sak Pier.”
This helps the driver meet you at the correct terminal.
Same-Day Lake Arrival or Stay Near the Pier?
If your ferry reaches Don Sak early enough, it is possible to continue directly to Cheow Lan Lake.
But remember that reaching Ratchaprapha Pier is not the end of the journey. If you are staying at a floating resort, you still need to travel into the lake by longtail boat.
For guests arriving from the islands later in the day, a more comfortable plan can be:
Koh Samui / Koh Phangan / Koh Tao → Don Sak → hotel near Ratchaprapha Pier
then
Next morning → Cheow Lan Lake
This avoids building a tight ferry–road–boat connection where one delay affects the entire itinerary.
