Khao Sok National Park is one of Thailand's most unique destinations: a vast emerald-green lake surrounded by ancient jungle, from which imposing limestone cliffs rise. The park's centerpiece is Cheow Lan Lake, an artificial reservoir with floating bungalows offering unforgettable overnight stays. The evergreen rainforest surrounding the lake is considered older than the Amazon and is home to a diverse array of wildlife, from elephants and macaques to hornbills and frogs.

Although Khao Sok has gained popularity recently, it still feels like a true adventure. The small village exudes a relaxed backpacker vibe, the eco-resorts are tucked away amidst a sea of ​​palm trees, and there are small waterfalls to discover near the park entrance. One night allows for a longboat trip into the heart of the lake, but a few extra nights offer time for jungle treks, wildlife viewing, and discovering hidden gems.

Khao Sok National Park was an exhilarating experience for us, completely different from exploring Thai cities or island hopping in the Andaman Sea. The sheer size of the lake is breathtaking, and the surrounding jungle landscape is reminiscent of Jurassic Park.

"Three Brothers", Khao Sok

Is Khao Sok worth a visit? Our experience

We first learned about Khao Sok National Park after hearing enthusiastic reports from other travelers. It was described as Thailand's "last great wilderness," which, in our experience, certainly rings true. So, after exploring Koh Samui and Koh Phangan, we decided to head to Surat Thani, where Khao Sok is located. The closer we got, the more dramatic the landscape became, and suddenly, as if from nowhere, enormous limestone cliffs appeared.

When we arrived in the village, only a few restaurants, tour operators, and small tour groups lined the streets – so it never felt crowded. And that's precisely what's so great about Khao Sok: it's not overrun by tourism. While many boats head out onto the lake daily, the park is so vast that you never feel confined. The lake alone covers 165 square kilometers, and the surrounding rainforest is the largest in southern Thailand.

Longtail boat tour to Khao Sok

Our accommodation in the village of Khao Sok

We chose the Khao Sok Palmview Resort mainly because we wanted to save money at this stage of our trip. It's a budget-friendly resort surrounded by palm trees and a variety of animals, such as horses and roosters. The wooden bungalows are basic, but comfortable enough for a few nights. The only downside was the lack of air conditioning, which made it quite hot and humid at night. Aside from that, it was a fantastic stay – the staff are incredibly friendly, and the village is easily reached in five minutes on foot through the palm trees.

Our boat tour on Cheow Lan Lake

We spent two nights at Palmview and dedicated the entire day to exploring Cheow Lan Lake in a small group. Back then, we simply drove to the village and booked with a local tour operator, but these days it's advisable to book at least one or two days in advance (especially during peak season). Almost all accommodations and tour operators in the area organize longtail boat tours, as well as jungle walks and night safaris. Our full-day tour included:

  • Shuttle transfer from the village
  • Longtail boat tour through Cheow Lan Lake
  • A stop at the famous limestone formations of the "Three Brothers" to take photos.
  • Lunch in one of the floating bungalows in the middle of the lake
  • A tour through the Pra Kai Petch Cave, famous for its grottos and bats.
  • Free time for kayaking on the lake, exploring small islands and the "skeleton trees"
  • Numerous opportunities to enjoy the breathtaking view of the lake.

    • The boat trip across the emerald-green waters of Cheow Lan Lake was one of the most surreal experiences of our Thailand trip. Almost every minute, we were treated to breathtaking bays and limestone cliffs, their edges fringed with dense forest. Our only regret was not having stayed in a floating bungalow, but that's definitely at the top of our list for our next visit.

    The best things to do in Khao Sok

    Take a longtail boat tour across Cheow Lan Lake

    If you only have time for one activity in Khao Sok National Park, like we did, then you absolutely must take a longtail boat tour on Cheow Lan Lake. This lake is the absolute highlight of the national park: a vast emerald-green lake surrounded by limestone cliffs and dense jungle. The water shimmers in an incredible emerald green and is always hypnotically calm, making a traditional longtail boat ride an equally entertaining and relaxing experience.

    Most guests book a full-day tour, which includes a visit to the "Three Brothers" limestone formations, a cave tour, time for swimming and kayaking, and a freshly prepared Thai lunch in one of the floating bungalows. However, the exact tour itinerary may vary depending on the operator.

    Early mornings are the best time to observe the low-hanging clouds or mist over the lake, while afternoon tours offer the chance to enjoy the sunset – an experience we had upon returning to the jetty at the end of the day. When we took the tour in February, the conditions were perfect: blue skies and mirror-like water. There was no wind, which made the heat oppressive. Therefore, be sure to dress appropriately for the weather.

    Embark on a jungle trekking tour in the ancient rainforest.

    The Khao Sok rainforest, unlike the lake, is not artificially created but a living ecosystem with dense vegetation, ancient trees, and the constant sounds of birds and insects. Wildlife, especially birds, butterflies, and lizards, is frequently observed on hikes in Khao Sok. From kilometer 3 onward on the main trail, a guide is mandatory for safety reasons. Here are some trekking options:

  • Half-day hikes: Ideal for casual hikers who want to hike on well-marked trails along rivers and banyan trees.
  • Full-day guided trekking tours: These tours lead deeper into the untouched nature of the jungle. You will search for unique plant and flower species, such as the Rafflesia flower.
  • Wildlife observation: With the help of park rangers, you will venture into the heart of the rainforest to follow the tracks, sounds, and movements of the animals.
  • Trekking tours during the rainy season: The rainforest is lush and green at this time, and the waterfalls also carry more water. However, leeches can be common and the paths can be slippery.

    • Stay overnight in a floating bungalow

    We regret not having stayed in a floating bungalow on our trip to Khao Sok. However, our budget was quite tight after several months of traveling in Thailand. If you can afford it, it would be an unforgettable experience. Imagine falling asleep (during the rainy season) to the sounds of the jungle and the gentle patter of the rain. The bungalows are located directly on the lake, far from cities and noise pollution – the peace and quiet is simply indescribable. Even just one night would be a dream!

    Visit the Khao Sok Ethical Elephant Sanctuary

    The Khao Sok Elephant Sanctuary rescues elephants that have spent their lives toiling in the timber and tourism industries. There, the gentle giants are cared for in a natural environment and can roam freely, eat, and bathe whenever they wish. Visitors can prepare food, watch the elephants wallowing in mud or bathing in the river, and peacefully walk alongside them. The sanctuary is considered a model for ethical and responsible elephant experiences in the region, placing great emphasis on education and observation.

    Take part in a nighttime safari in the rainforest

    Many jungle inhabitants are nocturnal – civets, bats, frogs, snakes, spiders, and night birds alike. Travelers can participate in guided night safaris and explore with experienced guides. Spiders are a major attraction, as the guides know the exact habitats of the large tarantulas. However, for those who are a bit afraid of spiders, this can be an intense experience. Therefore, be sure to wear sturdy shoes if you are traveling on foot!

    Visit the waterfalls around the park.

    Khao Sok is a natural paradise, and the waterfalls surrounding the park make this already incredible destination a true highlight. Mae Yai Waterfall is the most popular and easily accessible spot. It's located right off the main road, about 5-6 kilometers from the village. You can easily get there by scooter or walk directly from the village. Mae Yai Waterfall is distinguished by its impressive size and the sheer volume of water it carries, especially during the rainy season.

    Generally speaking, May to November is the best time to visit the Khao Sok waterfalls, as the water flow is stronger and the jungle landscape is more lush. However, they also offer exciting little adventures during the dry season.

    Accommodation near Khao Sok

    Budget: Khao Sok Palmview Resort

    We stayed at Khao Sok Palmview Resort and highly recommend it to budget-conscious travelers, backpackers, and anyone looking for rustic accommodation at a good price. The wooden huts are very basic, but the surrounding palm trees give them a special charm. The biggest drawback is the lack of air conditioning, but fans, mosquito nets, and natural shade provide some relief from the heat. Palmview is more like a farm than a resort, as many animals roam freely. So be prepared to be woken up by roosters crowing at dawn!

    Middle class: Our jungle house

    Our Jungle House offers unique treehouse accommodations nestled amidst lush jungle scenery. Some rooms boast breathtaking views of limestone cliffs. While the furnishings are simple, the house's minimalist, eco-friendly design provides all the amenities you would expect from a 3-star hotel. Opened in 1985 and recently renovated to an excellent standard, the lodge sits on a 10-hectare property along the Sok River and exudes absolute tranquility.

    Floating bungalow: 500 rai

    For those seeking a truly special experience, the 500 Rai Floating Resort offers the ultimate Khao Sok adventure. What could be more idyllic than villas built over the water, panoramic views, private balconies, and stylish rooms right on the shores of the stunning Cheow Lan Lake? It undoubtedly ranks among the most picturesque accommodations in all of Thailand.

    When should you visit Khao Sok?

    Dry season (December – April)

    As in most parts of Thailand, the most popular time to visit is from December to April. During this period, the weather is consistently good for longtail boat tours, kayaking, and trekking. Due to these favorable conditions, this period attracts the most visitors, especially around Christmas, New Year's, and early February.

    Green season (May – November)

    The rainy season in Khao Sok differs from many other parts of Thailand in that it is actually one of the best times to visit. While there is significantly more rain, the dramatic cloud formations and the burgeoning rainforest offer a visually spectacular experience. Tourist numbers decrease and hotels lower their prices, making the region ideal for backpackers or those seeking tranquility.

    How many days does it take to visit Khao Sok?

    1 night / 2 days

    Perfect for visitors with limited time, like us. You really only have time for one experience, and that should definitely be the longtail boat tour on Cheow Lan Lake. It offers a great introduction to the national park, but doesn't leave time for jungle hikes or other activities.

    2 nights / 3 days

    This is the ideal length of stay, especially if you plan to explore the jungle or visit the elephant sanctuary in addition to the boat trip on Cheow Lan Lake. However, keep in mind that getting to and from Khao Sok takes time. Therefore, plan your days carefully and allow yourself plenty of time. If in doubt, we recommend three nights.

    3 nights or more (recommended)

    Ideal for travelers who want to experience the park intensively, for example by spending a night in a floating bungalow followed by several nights in a treehouse in the jungle. This gives you enough time and space to explore the lake, the jungle, the waterfalls, and the elephant sanctuary, and to discover the region's hidden treasures off the beaten track.

    A tour in Khao Sok

    How to get to Khao Sok

    From Phuket

    Phuket is the most common way to get to Khao Sok. Shared taxis and private transfers run daily from various locations on the island; the journey usually takes 2.5 to 3 hours. Alternatively, you can take the public bus. While this is cheaper, the journey takes about 4 hours and you are only dropped off on the main road, not directly in the village – which is very inconvenient.

    From Surat Thani

    Surat Thani is the closest major transport hub to Khao Sok and has an airport for those flying from Bangkok. The journey from there takes approximately 1.5 to 2 hours. You can book a transfer directly at the airport (which reduces the travel time by 30 minutes, as the airport is located outside the city).

    From Koh Samui

    This is the route we took to Khao Sok, and it's the one we recommend if you're completing your Gulf Islands trip. Simply book a combination ticket, take the ferry or speedboat to Donsak Pier, and then continue directly to Khao Sok by shared taxi or private transfer. The entire journey takes about 6-7 hours, but just sit back and enjoy the scenery – the time will fly by!

    Tips for visiting Khao Sok

  • Book your floating bungalows early: The floating resorts can be fully booked months in advance, so it is advisable to secure your accommodation as early as possible.
  • Wear appropriate footwear: The jungle trails can be muddy and slippery, especially after heavy rain. Bring lightweight hiking boots or sturdy shoes with good tread.
  • Pack for the heat: We found the heat in February relentless, much more humid than in other parts of Thailand. Bring everything you need to stay cool and protect yourself from the sun.
  • Bring cash: ATMs in Khao Sok village are notorious for frequently running out of cash or breaking down unexpectedly. Therefore, it's advisable to carry sufficient cash. Many local tour operators and restaurants prefer cash, but in our experience, card payments were also possible.
  • Please visit us responsibly: Choose ethically oriented elephant sanctuaries, take your rubbish with you and be quiet on the lake – this is a place you want to enjoy in peace!
