Koh Tao is a 21 km² island in the Gulf of Thailand that punches far above its size. Most people show up for the diving — and fair enough, it’s one of the cheapest places on earth to get your PADI — but the things to do in Koh Tao go well beyond what happens underwater. Cliff jumping at Tanote Bay, hiking to viewpoints overlooking three bays, sunset bars on cliffsides, street food for 60 baht, a flying trapeze school that’s the only one in Thailand. We live here. This is what we actually do. For the full picture, start with our Koh Tao guide hub.
The best things to do in Koh Tao include scuba diving from 9,000 baht, snorkelling trips to Koh Nangyuan, cliff jumping at Tanote Bay, hiking John Suwan Viewpoint, and exploring Sairee’s street food and sunset bars. Most activities cost under 500 baht and suit complete beginners.

Water Activities — The Best Things to Do in Koh Tao
The water is the main reason Koh Tao sits on every backpacker’s route. Visibility regularly hits 15-20 metres, the marine life includes reef sharks, barracuda, and turtles, and you can dive or snorkel year-round. Here’s where to start if you’re after underwater experiences.
1. Scuba Diving
Koh Tao is one of the cheapest places in the world to get a PADI Open Water licence — around 9,000 baht for the full course, which you keep for life. Not ready for a full course? A single fun dive costs around 1,200 baht and gets you underwater the same day. Hundreds of dive shops keep quality high and prices honest.
We recommend Nitro as our go-to dive school — ask at Wonderland’s reception and we’ll sort it out. If you’d rather book online before arriving, try diving for a day with LBD (around 2,500 baht) or go the full PADI Open Water course over 2.5 days. Expect blue-spotted rays, sea turtles at close range, and at sites like Sail Rock, great barracuda schools. For the full breakdown, read our Koh Tao diving guide.
Cost: ~1,200฿ (fun dive) / ~9,000฿ (Open Water course)
Getting there: Dive schools pick you up from accommodation
Duration: 1 day (fun dive) or 2.5–4 days (Open Water)
Watch out for: Check medical requirements — some conditions prevent diving.
2. Snorkelling Trips
Snorkelling trips are one of the most popular things to do in Koh Tao for visitors on a short stay. Boats stop at 4-5 bays for about 40 minutes each, guides swim with you, all gear is included, and most trips throw in lunch. The Oxygen Tour is the one we sell at reception. Their First Light morning trip stops at Koh Nangyuan — the island next door with the famous sandbar viewpoint. Nangyuan charges 250 baht entry and bans outside plastic. Prefer a sunset finish? The BBQ and sunset cocktail tour skips Nangyuan and goes to deeper water where the coral is healthier.
Cost: ~800–1,500฿ depending on tour
Duration: 6–8 hours including transport
Watch out for: Nangyuan’s 250฿ entry fee isn’t always included in the tour price.
3. Kayaking & Paddleboarding
Almost every beach has rental shops — look for the 300-500 baht per hour signs along the sand. Sairee Beach is the spot for paddleboarding, especially at sunset. For kayaking, Aow Leuk is the move — paddle along the rocks to the left and you’ll find quieter water with better reef. Bring a snorkel, jump off when you spot a good patch.
4. Cliff Jumping at Tanote Bay
One of the most thrilling things to do in Koh Tao. Tanote Bay has an 8-metre cliff with bare-hands-on-rock climbing to the top. It’s committed: once you’re up, climbing back down is harder than jumping. The water below is deep, but jump feet-first and straight. Full details in our cliff jumping guide.
5. Freediving
Koh Tao’s freediving scene is growing fast. Apnea Total is the top school on the island — courses start from complete beginner and run about three days. The ocean here reaches 35-40 metres deep, with Aow Leuk the main training ground: the centre drops off to pure sand, perfect for depth practice. Courses start from around 7,000 baht.
Things to Do in Koh Tao on Land
The island is steep, green, and covered in viewpoints that earn every drop of sweat. Most hikes are under 30 minutes, but you’ll need decent shoes and a scooter for the approach roads.
6. Viewpoints & Hiking
John Suwan Viewpoint is the best on the island — 50 baht entry, 15-minute hike, and you can see Chalok Bay and Shark Bay from the southernmost tip. Go for sunrise or sunset. Love Koh Tao on the east coast overlooks Tanote Bay — 50 baht or buy a drink, opens 6am for sunrise. West Coast Viewpoint is a 20-minute uphill hike for the entire Sairee coastline — free entry, best at sunset.
The Laem Thian hike is the one most tourists miss. About 30 minutes starting from The Tarna Resort, the trail leads to an abandoned resort from 20 years ago built right over crystal-blue water. Three floors — the ground level is where everyone swims, the second floor has abandoned rooms with local artwork, and the top floor gives you a viewpoint over Laem Thian cape. Free, uncrowded, and one of the best things to do in Koh Tao if you like exploring off-trail. More routes in our hiking trails guide.
Entry: Free–100฿ depending on viewpoint
Getting there: Scooter to the trailhead, then on foot
Best time: Sunrise for east coast, sunset for west coast
Watch out for: Viewpoint roads are steep and loose gravel — ride carefully.
7. Climbing & Bouldering
The Bunker is the only bouldering gym on Koh Tao and also runs guided outdoor rock climbing on the island’s granite boulders. Koh Tao Climbing Club runs the outdoor trips if you want real rock under your fingers.
8. Muay Thai & Fitness
Monsoon Gym in Sairee has the best Muay Thai training on the island — plus BJJ, air-conditioned. CrossFit The Box in Mae Haad runs outdoor classes and boxing if you want a structured workout between dives. Both are solid ways to stay active without spending a full day on it.
“There is a different event every night in the common area from Mario Kart nights to Karaoke. You just wake up and something’s happening.”

Unique Things to Do in Koh Tao You Won’t Find Elsewhere
Most islands have diving and beaches. Koh Tao has a few experiences you genuinely can’t find anywhere else in Thailand — and they’re the kind of thing people talk about months later.
9. Flying Trapeze
Flying Trapeze Adventures is the only flying trapeze school in Thailand. Loads of Wonderland guests come back buzzing — patient instructors, real swings and catches, and one of those experiences people remember long after the tan fades.
10. Treasure Island Challenge
Treasure Island Challenge is a 6-hour island treasure hunt — puzzles, snorkelling, viewpoints, local food — great for groups or solo travellers who want a structured day that covers a lot of ground.
11. Mini Golf
There’s a mini golf course in the Sairee area that most tourists walk right past. Cheap, fun, and a good alternative to another bar night.
Best Food & Nightlife Things to Do in Koh Tao
Eating well on Koh Tao is easy and cheap — 60-80 baht gets you a full meal at street level, and the sunset bar scene is one of the best in the Gulf islands. Here’s where to go.
12. Street Food
Pancake stalls along Sairee and Mae Haad cook fresh for 60 baht. Near the Mae Haad 7-Eleven with the gas station, chicken skewers go for 20 baht each. For mornings, Patong Go Donuts & Coffee sells fried Thai donuts with condensed milk — order 60 baht worth and you’re full until lunch.
13. Local Restaurants
995 Roasted Duck in Sairee does duck and rice for 80 baht with remarkable speed — 15 minutes even when packed. Babaloo is right next to Wonderland — great vegan menu alongside Thai staples. Tra Kul Kao’s Kitchen nearby does authentic local dishes at honest prices. Full details in our restaurants guide.
14. Sunset Bars
Secret Bar is right next to Wonderland — stunning views and on clear evenings you can see the mainland. Arrive by 5pm. Lotus Beach Bar on Sairee has fire shows, Khao Soi, and your feet in the sand. Maya Beach Club is where the local expats go — directly at the beach, mellow atmosphere. A sunset drink on a clifftop is one of the simplest pleasures on the island, and it costs about 150 baht.
15. Plan Your Time — How Many Days on Koh Tao?
How long you stay changes what’s realistic. Here’s a rough breakdown.
| Time on island | What you can realistically do |
|---|---|
| 1 day | Snorkelling trip (4-5 bays) + Sairee sunset + street food dinner |
| 2-3 days | Add a fun dive or try-dive, hike John Suwan, cliff jumping at Tanote |
| 4-7 days | Full PADI Open Water, multiple viewpoints, freediving taster, flying trapeze |
| 1-2 weeks | Advanced diving, Laem Thian hike, Treasure Island Challenge, every bay explored |
Most people arrive planning 3 nights. At Wonderland, the average is closer to a week — 1 in 5 guests extends their stay. There’s a pattern: you come for diving, stay for the people, and leave saying “I should have booked longer.” Read our 1-day itinerary if you’re short on time, or the budget guide if you’re watching every baht.
