Khao Sok National Park is one of the most unique destinations in Thailand: a massive emerald lake surrounded by ancient jungle, where limestone cliffs rise dramatically from the water. The park’s centrepiece is Cheow Lan Lake, a man-made reservoir home to floating bungalow accommodation that makes for once-in-a-lifetime overnight stays. The evergreen rainforest wrapping around the lake is considered to be older than the Amazon, with all sorts of creatures roaming freely, from elephants and macaques to hornbills and frogs.

Although Khao Sok has become popular in recent years, visiting the park still feels like you’re embarking on a true “off-the-beaten-path” adventure. The small, sleepy village offers a chilled-out backpacker vibe, the eco-resorts hide beautifully amongst a sea of palm trees and there are little waterfalls to be explored near the park entrance. Staying overnight allows you to take the longtail boat trip into the heart of the lake but a few extra nights gives you the time to go jungle trekking, wildlife spotting and discover hidden gems.

For us, Khao Sok National Park was an exhilarating experience, very different from what we’ve seen in Thailand’s cities, islands and countryside. The lake’s size is just astonishing, and the jungle landscape encompassing it is like something out of Jurassic Park. Very few places in Thailand feel this rugged and wild, which is why you absolutely have to visit!

Is Khao Sok Worth Visiting? Our Experience

We came across Khao Sok National Park after seeing it promoted all over social media and hearing rave reviews from other travelers. It was described as Thailand’s “last great wilderness”, which from our experience is pretty accurate. We headed down to Surat Thani, where Khao Sok is located, after exploring Koh Samui and Koh Phangan. The closer we got, the more dramatic the landscape became. Villages turned into winding jungle roads and huge limestone cliffs appeared out of nowhere!

When we arrived at the village the streets were lined with just a few restaurants, tour operators, and small groups of travelers - so it never felt crowded. And that’s the great thing about Khao Sok, it’s not currently overwhelmed by tourism. Yes, there are plenty of boats that venture out onto the lake everyday but the park is so big that you never feel like you’re stepping over each other. In fact, the lake alone covers 165 square kilometers and the virgin forest surrounding it is the largest in southern Thailand. Khao Sok is worth visiting because it’s so vast, making it easy to find areas that feel completely untouched.

Where we Stayed at Khao Sok Village

We picked Khao Sok Palmview Resort, mainly because we were trying to keep costs down during this point of our trip. This is a budget-friendly “resort” surrounded by palm trees and an array of animals like horses and roosters. The wooden cottages are basic but comfortable enough for a few nights. The only real downside to the place was having no air-conditioning, which made our nights quite hot and sweaty. Apart from that, it was a fantastic stay - the staff are super friendly and it’s an easy 5-walk minute walk through palm trees to the village.

Our Boat Tour on Cheow Lan Lake

We spent two nights at Palmview and dedicated our full day to exploring Cheow Lan Lake on a small group tour. At the time, we just rocked up to the village and booked with a local tour operator but these days it’s probably safer to book at least 1-2 days in advance (especially during the busier peak season). Nearly every accommodation and tour provider in the area can organise longtail trips, as well as jungle treks and night safaris. Our full-day tour included:

Shuttle transfer from the village
Longtail boat tour through Cheow Lan Lake
A stop at the iconic “Three Brothers” limestone formations to take photos
Lunch at one of the floating bungalow accommodations in the middle of the lake
A tour of Pra Kai Petch Cave, famous for its narrow passages, caverns and bats
Free time to go kayaking on the lake, exploring little islets and the “skeleton trees”
Plenty of opportunities to soak up the extraordinary lake views.

Cruising across the emerald waters of Cheow Lan Lake was one of the most surreal experiences we’ve had in Thailand. Every few minutes or so we were greeted to uniquely-shaped bays and limestone cliffs with dense forest spilling down their edges. Our only regret was not staying overnight in a floating bungalow. But that’s already on our bucket-list for next time.

6 Best Things to Do in Khao Sok

1. Take a Longtail Tour Through Cheow Lan Lake

If you only have time to do one activity in Khao Sok National Park, which was the case for us, make it the longtail trip across Cheow Lan Lake. This is the national park’s crown jewel: a colossal emerald reservoir surrounded by unique limestone karsts, untamed jungle shores, and hidden coves. The water has this incredible emerald color and it stays mesmerically calm throughout, making a traditional longtail trip both fun and relaxing.

Most people join a full-day tour which includes a stop at the “Three Brothers” limestone formations, a cave visit, time to swim and kayak, and a freshly cooked Thai lunch at one of the floating bungalows. Although tour itineraries may differ depending on who you book with.

Early morning tours are best for seeing low clouds or layers of mist lingering on the lake, while afternoon tours are best for witnessing the sunset - something we were treated to upon returning back to the pier at the end of the day. When we did the tour in February, the conditions were perfect: blue skies and calm waters. There wasn’t a breath of wind but this did make the heat feel stifling, so just ensure you’re dressed appropriately for the weather.

2. Go Jungle Trekking in the Ancient Rainforest

Khao Sok’s rainforest isn’t man-made like the lake, it’s a living and breathing ecosystem complete with thick vegetation, ancient trees, and the constant sound of birds and insects. Spotting wildlife on a Khao Sok trek is extremely common, especially birds, butterflies and lizards. You might also see hornbills or gibbons if you get super lucky. Going with guides is a requirement for any trek past the 3km mark on the main trail. This is to ensure a safe experience, as it’s easy to get lost in the sprawling rainforest. Here are your options:

Half-Day Hikes: Perfect for casual hikers who want to walk along well-marked trails, past rivers and ancient Banyan trees.
Full-Day Guided Treks: These treks go deeper into the thick, wild side of the jungle. You’ll search for unique plant and flower species, such as the Rafflesia flower.
Wildlife Treks: With the help of park rangers, you’ll head into the heart of the rainforest to follow the animal’s tracks, sounds and movements.
Rainy Season Treks: The rainforest is green and lush during this period, with higher waterfall flow as well. However, leeches can be prevalent and trails can be slippery.

3. Stay Overnight in a Floating Bungalow

One thing we regret is not staying in a floating bungalow on our trip to Khao Sok, however we were pretty tight on money after traveling around Thailand for several months. If you do have the budget, this will be one of the most unforgettable travel experiences you ever have. Just imagine falling asleep above still, jade-green water and waking up to the sound of birds as the sun slowly illuminates the limestone cliffs. These bungalows sit directly on the lake, far from any towns or noise pollution, so the sense of serenity is extraordinary.

Mornings would be peaceful as the cliffs glow gold and the lake remains glassy. At night, you’ll drift off to the sound of geckos, soft jungle calls and (during the wet season) the gentle patter of rainfall echoing across the water. Even a single night would be a dream!

4. Visit the Ethical Khao Sok Elephant Sanctuary

Khao Sok Elephant Sanctuary rescues elephants that have spent their lives toiling away in the logging and tourism industries. They care for these gentle giants in a natural environment, allowing them to roam freely and feed and bathe as they please. Visitors to the sanctuary can prepare food, watch them take mud baths or bathe in the river, and walk alongside them peacefully. The sanctuary is considered the gold standard of ethical and responsible elephant experiences in the area, focusing on education and observation above all else.

5. Join a Nighttime Safari in the Rainforest

At night, Khao Sok National Park changes personality completely. Many of the creatures dwelling in the jungle become active - whether it’s civets, bats, frogs, snakes, spiders or night birds. Travelers can join guided night safaris at Khao Sok, either on foot or by boat, and head out with trained guides along quiet forested paths, following the sounds of insects and spotting tiny eyes lurking in the trees. Spiders are a major drawcard, as the guides know the specific burrows where the large tarantulas live. However, if you’re slightly arachnophobic, this can be an intense experience. Just be sure to wear closed-toed shoes if you’re going by foot!

6. Visit the Waterfalls Around the Park

Khao Sok is a natural paradise and the waterfalls surrounding the park add the cherry on top to an already incredible destination. Mae Yai Waterfall is the most popular and accessible spot, located right off the main road, about 5-6 kilometers from the village. It’s easy to take a scooter here and visit the waterfall, or walk directly from the village. Mai Yai is defined by its tall stature and powerful flow, especially during the wet season.

Another great waterfall to visit is Wing Hin Waterfall. It’s known for having boulders and natural pools to relax in on a hot day. As a general rule, May to November is the best time to chase the waterfalls of Khao Sok, when the water flow is heavier and the jungle landscape is greener. But even during the dry season, they still make for fun little adventures.

Where to Stay Near Khao Sok

Budget: Khao Sok Palmview Resort

Khao Sok Palmview Resort is where we stayed and we’d recommend it to budget travelers, backpackers or anyone who likes rustic accommodation at a good price. The wooden cottages are very simple but the surrounding palm trees add a touch of charm. The biggest trade-off is the lack of air-conditioning but the fans, mosquito nets and natural shade help. Palmview is almost like a farm, rather than a resort, with lots of animals roaming around. So just be aware that you might wake up at the crack of dawn to the sound of roosters!

Mid-Range: Our Jungle House

Our Jungle House offers unique treehouse accommodation, in a lush jungle setting, with views of limestone cliffs from some of the rooms. While it has basic amenities, due to its stripped back eco-friendly ethos, it still offers all the comforts you’d expect from a 3-star hotel. It first opened in 1985 but was recently renovated to bring it up to an excellent standard. The lodge sits on 25 acres along the Sok River, oozing tranquility throughout.

Floating Bungalow: 500 Rai

For those willing to splurge, 500 Rai Floating Resort is the ultimate Khao Sok experience. What’s not to love about overwater villas, panoramic views, private balconies and stylish rooms set on the magnificent Cheow Lan Lake?! It has to be one of the most scenic stays in all of Thailand.

When to Visit Khao Sok

Dry Season (December – April)

Like most of Thailand, December through to April is the most popular time to visit. It provides the most consistently good weather for longtail tours, kayaking and trekking. Rainfall is minimal, the lake stays calm, and visibility is superb for photography. Since the weather is so favorable, this period attracts the highest number of visitors, especially around Christmas, New Year and early February.

Green Season (May – November)

The wet season in Khao Sok is different to much of Thailand, in the fact that it’s actually one of the best times to visit. There’s definitely more rainfall, but the dramatic cloud formations and greening rainforest gives it a visually spectacular feeling. Tourist numbers drop and hotels lower their prices as well, making it ideal for backpackers or just those seeking solitude.

How Many Days for Khao Sok?

1 Night / 2 Days

Perfect for visitors who are short on time, like we were. You really only have time to do one experience, which has to be the longtail boat tour of Cheow Lan Lake. It’s a nice introduction to the national park but doesn’t leave any room for jungle treks or additional activities.

2 Nights / 3 Days

This is the ideal length for most people, especially if you want to explore the jungle or visit the elephant sanctuary in addition to taking the Cheow Lan Lake boat tour. But just note that you’ll lose time traveling to and from Khao Sok, so ensure you’ve planned out your days properly and aren’t rushing. If in doubt, stay for three nights.

3 Nights or More (Recommended)

Best for travelers who want to fully immerse themselves in the park, which could include a night in a floating bungalow and then a few nights in a jungle treehouse. This will give you the time and space to explore the lake, jungle, waterfalls, elephant sanctuary and head a little off-the-beaten-track to discover the region's hidden gems.

How to Get to Khao Sok

From Phuket

Traveling from Phuket is the most common route to reach Khao Sok, with shared minivans and private transfers running daily from different points of the peninsula, normally taking around 2.5-3 hours. Another option is jumping on the public bus. Although it’s cheaper, it can take around 4 hours and only drops you on the main highway, not in the village itself, which is very inconvenient.

From Surat Thani

Surat Thani city is the closest major hub to Khao Sok, equipped with an airport for those looking to fly in. Transfers from here take around 1.5-2 hours, and you can even book transport from the airport itself (which shaves 30 minutes off the trip as the airport is located outside the city).

From Koh Samui

This is the route we took to Khao Sok, and one that we recommend if you’re finishing up your trip around the Gulf Islands. Despite it being a long journey, it transports you from Thailand’s islands to its jungles with ease. Simply book a combined ticket, jump on the ferry or speedboat to Donsak Pier and then continue with a shared minivan or private transfer directly to Khao Sok village. The total journey takes around 6-7 hours but just sit back and enjoy the scenery, and the time will fly by!

Tips for Visiting Khao Sok

Book the Floating Bungalows Early: The most popular floating resorts can sell out months in advance, so lock in your accommodation as soon as possible.
Wear Proper Shoes: The jungle trails can get muddy and slippery, especially after heavy downpours. Bring lightweight hiking boots or solid walking shoes with good grip.
Pack for the Heat: We found the heat in February to be relentless, a lot muggier than other parts of Thailand. Bring all the essentials to keep yourself cool and protected from the sun.
Bring Cash: ATMs at the Khao Sok village are known for running out of cash or breaking down unexpectedly, so having plenty of cash on you is a good idea. Many tour operators and local restaurants prefer cash, though from our experience cards were also accepted.
Visit Responsibly: Choose ethical elephant sanctuaries, pack out what you pack in, and keep the noise down when out on the lake - this is a place you’ll want to enjoy quietly!
