Koh Tao may be one of the smallest islands in the Gulf of Thailand, but it offers far more than just world-class diving. From snorkeling with sea turtles and hiking to panoramic viewpoints to relaxing on white-sand beaches and watching unforgettable sunsets, there is something for every type of traveler.
Whether you’re visiting for a few days or a longer stay, you can easily combine adventure and relaxation. Spend the morning exploring coral reefs, the afternoon on a quiet beach, and the evening enjoying Koh Tao’s lively restaurants and beach bars.
This guide covers the 12 best things to do in Koh Tao, including diving, snorkeling, hiking, beaches, viewpoints, boat trips and nightlife, helping you plan a trip that makes the most of your time on the island.
Koh Tao’s waters are the main reason most people come here, and rightly so. These are the water-based activities worth building your trip around.
Shark Bay is the easiest introduction to Koh Tao’s marine life. Baby blacktip reef sharks patrol the shallows, resident turtles pass through regularly, and the coral supports a huge variety of colorful reef fish. It works equally well for first-time snorkelers and experienced ones.
Go early in the morning when the water is calm and marine life is most active. You can rent snorkeling gear locally or bring your own, and please avoid touching the coral.
Among the best beaches on Koh Tao, several spots also offer great snorkeling conditions depending on visibility and tides.
If you want to go beyond the surface, La Bombona Diving runs scuba courses and fun dives for every level, from complete beginners to certified divers looking for their next challenge. Instructors keep groups small and put a strong focus on marine conservation, so you get a safe, personal experience rather than being one of thirty divers on a boat.
Expect to see trevallies, barracudas and, depending on the season, a chance of a whale shark sighting.
If you’re new to diving, start with the Try Dive. If you want a full certification, the Open Water course is the internationally recognized route, and the Explorer 30 course is worth a look if you want to keep progressing after that.
Maya Beach Club’s calm waters make it a great spot for stand-up paddle boarding, whether you’re picking it up for the first time or you’re a seasoned paddler. Rentals and lessons are both available, and it doubles as a solid core workout while you take in the coastline.
It’s also part of Koh Tao’s laid-back beach scene, where several of the best bars with activities on Koh Tao combine food, drinks and water sports in one place.
Check the weather and tide conditions before you head out, and consider timing your session for sunset.
Unseen Tours takes you to the island’s hidden and lesser-known snorkeling spots, guided by marine conservationists who explain what you’re looking at as you go. Expect vibrant coral reefs, tropical fish and a decent chance of spotting a turtle, without having to plan your own route around the island. For travelers looking for the best boat tours, this experience combines guided snorkeling with access to lesser-known marine sites.
Koh Nang Yuan is a short boat ride from Koh Tao and one of the most photographed spots in Thailand: three small islands connected by a white sandbar. Snorkel the Japanese Garden, hike up to the viewpoint for a panoramic shot of the sandbar below, or just relax on the beach for the day.
Koh Nang Yuan is a conserved area with a small entrance fee. Respect the rules, including any restrictions on single-use plastics, to help keep it as clean as it looks in photos.
Koh Tao isn’t only about the water. The island’s hills and coastline give you plenty of reasons to get out and explore on foot.
This moderately challenging hike rewards you with views over Koh Tao’s lush greenery and coastline. It’s a manageable few hours out and back, making it an easy way to spend a morning or afternoon. Wear comfortable walking shoes, bring plenty of water and take your camera. It’s also considered one of the best hiking trails on Koh Tao for visitors looking to combine light adventure with scenic viewpoints.
John Suwan Viewpoint is one of the best viewpoints on Koh Tao, offering a 360-degree view of the island. It is one of the most photographed spots on Koh Tao, especially at sunrise or sunset. The hike up is short but steep, so expect a bit of a workout. Watch your footing near the top, as the rocks can be slippery.
For a different angle on the island, head to Love Koh Tao Viewpoint, best known for sunrise views and a relaxed cafe at the top, or Mango Viewpoint in the north, one of the best sunset spots on Koh Tao. Both charge a small entrance fee that typically includes a drink, and both are easy to combine with a scooter tour of the island.
Goodtime Adventures runs climbing and abseiling courses and guided climbs for every level, from first-timers to experienced climbers. The island’s rocky terrain offers a genuine range of routes, and the company prioritizes eco-friendly gear and practices. Dress appropriately and bring plenty of water.
Oxygen Tours runs daytime and nighttime fishing trips to some of the best fishing spots around the island, with all gear, bait and food included. A standard tour picks you up from your hotel between 9:00 and 9:30 AM, meets at Mae Haad pier, and returns you around 5:30 PM. It’s also considered one of the best fishing tours in Koh Tao for visitors looking for a fully guided angling experience.
Sairee Beach is the longest and busiest beach on Koh Tao, and the natural base for most visitors. Restaurants, cafes and beach bars line the sand, kayaks and paddleboards are easy to rent, and the sunset here is one of the best on the island. It’s also the easiest starting point if you’re deciding where to stay.
If you want a low-key day, the pool at Savage Hostel is a popular hangout even if you’re not staying there. It is one of the best hotel pools on the island. It has a lively, social atmosphere with a bar right by the water, making it a good spot to cool off after diving or hiking and meet other travelers. Note that the pool is open to non-guests after 5 PM.
Sairee Beach is the center of Koh Tao’s nightlife. Here’s where to go depending on the kind of night you’re after.
| Looking for | Go to |
|---|---|
| Beachfront party games and loud music | Fishbowl, right on the sand at Sairee Beach |
| Fire shows under a landmark leaning palm | Lotus Bar |
| The Koh Tao Pub Crawl meeting point | Choppers |
| Karaoke and quiz nights | The Local |
| Upscale sunset cocktails | Maya Beach Club, Mae Haad |
| A different kind of show | Queen’s Cabaret |
If you’re staying outside Sairee Beach, arrange safe transport back to your accommodation.
The best conditions for diving, snorkeling and general visibility on Koh Tao run from February to September, when the seas are calmest and clearest. That said, Koh Tao is enjoyable year-round, and the quieter monsoon months bring their own advantages, including thinner crowds at the viewpoints and dive sites.
Koh Tao’s roads are hilly and can be steep or unpaved in places. Renting a scooter is the most popular way to get around, but ride carefully, as accidents are common. If you’d rather not drive, songthaews (shared local taxis) and water taxis are easy alternatives for getting between bays.
| If you want | Best pick |
|---|---|
| To try diving for the first time | Try Dive with La Bombona Diving |
| An easy, guided snorkel with marine life | Shark Bay or an Unseen Tours trip |
| The most iconic photo spot on the island | Koh Nang Yuan |
| A workout with a view | John Suwan Viewpoint or the Laem Thian Trail |
| An adrenaline rush | Rock climbing and abseiling with Goodtime Adventures |
| A low-key beach day | Sairee Beach or the pool at Savage Hostel |
| A big night out | Sairee Beach bars, starting at Fishbowl or Choppers |
Whether you’re here to dive, snorkel, hike or just watch the sunset from Sairee Beach, Koh Tao has enough packed into its small footprint to fill every day of your trip. If diving is on your list, check out La Bombona Diving’s Koh Tao scuba diving courses, guided fun dives and snorkeling experiences to help you discover the island’s incredible marine life.
Koh Tao is surrounded by healthy coral reefs that support a wide range of tropical fish, sea turtles and even juvenile reef sharks. Shark Bay and Aow Leuk are the go-to spots for beginners and experienced snorkelers alike.
Most tour operators on the island let you book directly through their website, by phone or in person at their office, usually a day or two in advance. For a private boat, expect to confirm your group size, preferred stops and pickup time, and to pay a deposit to hold the booking. During high season, booking a few days ahead is worth it since the best boats fill up quickly.
The Laem Thian Trail offers some of the best all-round coastal views on the island for a moderate effort. If you want the single best panoramic photo spot with a shorter, steeper climb, John Suwan Viewpoint is the island's most famous.
Bring reef-safe sunscreen, a hat, plenty of water and cash for the entrance fee. If you're snorkeling, pack your own mask and snorkel if you have them, along with a change of clothes and a dry bag for your phone and valuables. Leave single-use plastics behind, as they aren't allowed on the island.
Yes. Goodtime Adventures offers guided climbs and courses for all experience levels, with all necessary gear included, so you don't need any prior climbing experience to join.
Yes. While diving and snorkeling are the island's main draw, Koh Tao also has hiking trails, viewpoints, waterfalls, beach clubs, rock climbing, fishing tours and a lively nightlife scene — enough to fill several days even if you never put on a mask.
Snorkeling, hiking to the island's viewpoints, stand-up paddle boarding, rock climbing, a day trip to Koh Nang Yuan and relaxing on Sairee Beach are all excellent options if diving isn't for you.
Three to four days are usually enough to cover the island's highlights at a relaxed pace, including a day for diving or snorkeling, a day trip to Koh Nang Yuan, and time for hiking and the beach. If you're planning to get your Open Water certification, budget at least three to four days for the course itself.
It depends on what you're after. Koh Tao is smaller, quieter and built around diving, which suits travelers who want a relaxed, dive-focused trip. Koh Samui is larger and more developed, with more resorts, shopping and nightlife options, which suit travelers looking for a broader holiday.
Yes, sea turtle sightings are common around Koh Tao, especially at Shark Bay and Koh Nang Yuan. Sightings are never guaranteed since these are wild animals, but they're a regular part of snorkeling and diving trips around the island.
