A lot of people treat Surat Thani as just a stopover on the way to Koh Samui, but the mainland actually has plenty to keep you busy — from a lake set among limestone mountains that's good enough to make global lists, to a rainforest said to be older than the Amazon, to thousand-year-old temples from the Srivijaya kingdom. We've grouped the attractions into three tracks — lake and forest, islands, and culture — so you can pick the trip that suits you.
Lake & rainforest: Cheow Lan and Khao Sok
If you only have time for one place in Surat Thani, most people choose Cheow Lan Lake, because those limestone peaks rising out of emerald-green water are the image people remember of this province. Both the lake and Khao Sok National Park sit in the west of the province, about 1.5–2 hours' drive from the city.
Ratchaprapha Dam (Cheow Lan Lake)
A lake set among limestone mountains in Ban Ta Khun district, nicknamed the "Guilin of Thailand." The highlights are longtail boat rides past the Sam Kloeng peaks, kayaking, and overnight floating raft houses. Early mornings bring mist drifting over the water that's genuinely beautiful.
PhanomKhao Sok National Park
An ancient tropical rainforest in Phanom district with nature trails, waterfalls, caves, river tubing, and spots to see Rafflesia (the world's largest flower). Entry is 300 THB for foreigners, 100 THB for Thais.
AdventureKhao Sok waterfalls & caves
Beyond the lake, Khao Sok has several tiered waterfalls and limestone caves, including Nam Talu Cave where you have to wade through water to get in. Good for adventurous types who want a proper hike.
Raft house tips
Floating raft houses on the lake need to be booked ahead — they fill up fast on long weekends. Raft packages including meals and a boat ride start at roughly 1,500–2,500 THB per person depending on whether it's a ranger station or a private operator. Go midweek and you'll get the place almost to yourself.
Want more out of Surat Thani? Book tours & activities
Booking online ahead on Klook or GetYourGuide is usually cheaper than the gate and skips the queue. Pick only the experiences you actually want — prices and availability are shown live on each site.
Islands: Samui, Phangan, Tao
Surat Thani is the gateway to the islands in the middle of the Gulf of Thailand. Ferries and speedboats leave Don Sak pier and piers in town every day, taking about 1.5–2.5 hours depending on the island and the type of boat.
Koh Samui
The biggest island, with Chaweng and Lamai beaches, the Big Buddha, and restaurants and hotels at every price point. Works for both families and couples. You can visit year-round, but the rainy stretch runs roughly Oct–Dec.
Party + chillKoh Phangan
Famous for the Full Moon Party at Haad Rin, but the other side of the island is quiet and laid-back, good for relaxing and yoga retreats. Plenty of white-sand beaches and snorkelling spots.
DivingKoh Tao
A diver's favourite, with some of the cheapest Open Water courses in the world. Clear water, coral and sea turtles. Good for first-timers and certified divers alike.
If you're already touring the mainland and want to add an island, plan on at least 2 nights per island, because the trips out and back eat up a fair bit of time. Don Sak pier is the main departure point for car ferries, while passenger speedboats leave from several piers in town.
Buying boat tickets
Combined bus + boat tickets (Lomprayah / Seatran / Raja Ferry) can be booked online in advance and are often cheaper than buying at the pier. Check the schedule carefully, because during monsoon season (Oct–Dec) some sailings may be cancelled.
Culture: Chaiya and the Srivijaya town
Chaiya district, in the north of the province, was once the centre of the Srivijaya kingdom over a thousand years ago. Today there are still traces to explore — old stupas, a museum, and a meditation centre that's nationally known.
Wat Phra Borommathat Chaiya Ratchaworawihan
A Srivijaya-style stupa more than 1,200 years old, one of the oldest and best-preserved Buddhist monuments in Thailand. It enshrines relics of the Buddha and is deeply revered by southerners.
Suan Mokkhaphalaram (Suan Mokkh)
A forest meditation centre founded by Buddhadasa Bhikkhu in 1959. Known for its "Spiritual Theatre," dharma puzzle paintings, and curved-stone courtyard, with a shaded, peaceful atmosphere.
Chaiya National Museum
Holds Srivijaya-era artefacts excavated in the area, including a replica of the Avalokiteshvara Bodhisattva (the original is in Bangkok). A good stop right after the Wat Phra Borommathat.
Ban Khlong Sai Coconut-Picking Monkey Training Centre
In Tha Chang district, a long-running centre that trains pig-tailed macaques to pick coconuts, with demonstrations for visitors. A local tradition that's hard to find elsewhere — check the schedule and contact them ahead.
Surat Thani City Pillar Shrine
A city pillar shrine in Srivijaya architecture in the centre of town. Locals come to pay respects and ask for blessings. It's near the Tapi River, an easy walk into the rest of town.
Khao Tha Phet
A low hill near town with a nature study centre and viewpoints over the city and the Tapi River. Good for a morning walk and photos of the town.
Dressing for temples
Wat Phra Borommathat Chaiya and Suan Mokkh are sacred places — dress modestly, cover your shoulders and knees, take your shoes off before entering the ordination hall, and keep your voice down in the meditation areas.
The Tapi River town and waterfront
The town of Surat Thani sits on the Tapi River, which flows out into Bandon Bay. In the evening the waterfront has markets and restaurants to stroll through — a good way to wrap up the day before heading out to the islands or home.
- San Chao Market (Tapi riverside market) — an evening market by the river with southern Thai snacks, sweets and sunset views.
- Bandon Bay — the mouth of the Tapi River, known for its oysters and seafood. A good spot to stop for a fresh seafood meal.
- Surat Thani night market — evening street food in town, where you can graze through both savoury dishes and desserts.
How to plan a trip that's worth it
Surat Thani's attractions are quite spread out — the lake and Khao Sok are in the west, Chaiya is in the north, and the islands are out in the Gulf. So it's best to plan your route by zone. Here's a sample 2-day, 1-night trip focused on nature and culture, not including island hopping.

Cheow Lan Lake–Khao Sok
Getting around the province
Distances between the sights are long and public transport isn't very convenient. If you're travelling as a group, renting a car and driving yourself, or hiring a car with a driver for the day, gives you much better control over your time — especially for the lake and Chaiya.
