Top 5 Things To Do in Koh Tao, Thailand

1. Best Beaches in Koh Tao

Koh Tao may not have the biggest beaches compared to places like Koh Samui or Koh Phangan, but what it lacks in size, it makes up for in character and underwater beauty. With crystal- clear waters, vibrant coral reefs, and relaxed vibes, the island’s beaches are perfect for swimming, snorkeling, or just unwinding with a drink in hand. Here are a few favorites to check out:

Sairee Beach

This is the main beach on the island and also the liveliest. Stretching over two kilometers along the west coast, Sairee Beach is lined with beach bars, restaurants, dive shops, and hostels, making it the hub of Koh Tao’s nightlife and diving scene. It’s also where you’ll arrive if coming from Koh Samui or Koh Phangan. While the swimming here isn’t the best due to shallow waters and boats, the sunsets are stunning. Grab a cocktail and sink into the sand, the whole beach glows in hues of orange and pink at dusk. For divers, Big Blue Diving is one of the top-rated dive schools here. And if you’re in the mood for yoga or a Thai massage, check out Blue Chitta or Infinity Koh Tao.

Shark Bay (Haad Tien)

Located on the southeastern side of the island, this bay is named for a reason, it’s home to Blacktip Reef Sharks, which you can snorkel with safely. Don’t worry, they’re harmless and used to human presence. The bay is backed by luxurious resorts, tall coconut palms, and calm, clear waters. You can get here by motorbike or, more conveniently, by joining a snorkeling tour, which often includes this bay as a stop.

Freedom Beach

Tucked away in the south, Freedom Beach is a small hidden gem accessible by motorbike or boat. Its calm, turquoise water and shallow reefs make it a great spot for a relaxed swim or easy snorkeling session. It’s not commercialized, so it feels peaceful, a quiet break from the busier beaches.

2. Best Viewpoints in Koh Tao

If you’re into sweeping views and short hikes, Koh Tao won’t disappoint. Despite its small size, the island is packed with stunning viewpoints, from lush jungles to dramatic coastlines. Most viewpoints are on private land, so expect a small entry fee.

John Suwan Viewpoint

Often considered the best viewpoint on the island, John Suwan offers a breathtaking panorama over both Shark Bay and Chalok Baan Kao. It’s about a 20- minute walk up a well- marked trail from the parking lot. Arrive early for sunrise if you want a quieter, cooler climb. Sometimes there’s a 50 Baht entry fee, sometimes not, just a heads-up.

Love Koh Tao Viewpoint

Perched above Tanote Bay on the east coast, Love Koh Tao is a fantastic sunrise spot and a chill place to enjoy a juice or lunch with a view. Entry is just 20 Baht, or free if you order something at the café. The spot is also Instagram-friendly, with colorful signs, netted hammocks, and classic panoramic shots.

Mango Viewpoint

Located high in the north of the island, Mango Viewpoint offers a majestic view over Sairee Beach and the western coastline. The road is steep, your scooter might not make it all the way up, but once there, the vibe is super relaxed. Expect to pay 100 Baht to enter, and enjoy a fresh juice, board game, or hammock session while taking in the view.

Koh Nang Yuan Viewpoint

Just off the northwest coast of Koh Tao lies Koh Nang Yuan, a tiny trio of islands connected by a picture-perfect sandbar. It’s one of the most photographed spots in the Gulf of Thailand, and for good reason. A 15- minute hike (with a bit of scrambling at the end) takes you to the famous Koh Nang Yuan viewpoint, where you’ll get a stunning panoramic view over the sandbar and turquoise waters below.
The island is a popular stop on snorkelling tours, but if you want more time to explore or just chill on the beach, you can take a private taxi boat from the northern end of Sairee Beach. The roundtrip fare is around 600 baht, so it’s worth asking around to share with other travelers.

There’s also an entry fee of 250 baht, and the island is open to visitors from 9:30 AM to 5:00 PM. Keep in mind: plastic bottles and drones are not allowed, and security will check your bags upon arrival. There’s only one restaurant on the island, and it’s quite pricey, so consider bringing snacks (in eco-friendly packaging!) if you’re planning to stay longer.
Whether you go for the viewpoint, the snorkeling, or just to see the sandbar in real life, Koh Nang Yuan is one of the most iconic day trips from Koh Tao.

3. Paddleboarding & Kayaking at Sairee Beach

If you’re looking for a peaceful way to enjoy the water, stand- up paddleboarding (SUP) or kayaking at Sairee Beach is a must. The calm sea and stunning sunsets here make it the perfect place to unwind on the water, especially late in the afternoon when the golden light hits the ocean.

There are plenty of spots offering paddle board rentals, including a well-known setup near Maya Beach Club. Look out for signs that say “SUP Tao”, they’re easy to find along the beach.

Prefer something more stable and want to explore a bit farther? Kayaking might be the better option. Many waterfront hotels offer kayaks for guests, or you can rent one from vendors right on Sairee Beach. If you’ve got the time, consider keeping the kayak for a full day so you can paddle to hidden bays and even pack a picnic to enjoy along the way.

4. Scuba Diving & Snorkeling in Koh Tao

Koh Tao is renowned for its incredible scuba diving and snorkeling opportunities, and it’s not just hype, this little island delivers. If you’ve ever thought about getting your PADI certification, there’s probably no better place to do it. Not only is it one of the most affordable spots in the world to get certified, but the conditions are ideal: warm waters, excellent visibility, and vibrant marine life.

There are dozens of dive schools on the island offering a variety of packages, many of them include accommodation and lessons bundled together, which can be a great deal. While we can’t vouch for a specific company, it’s worth reading reviews or just walking around Sairee Beach to chat with instructors and get a feel for each school. Plan for at least 3 to 5 days if you’re doing the full certification.

If scuba diving isn’t your thing, snorkeling in Koh Tao is just as rewarding. The island’s shallow reefs, crystal-clear water, and abundant marine life make it easy to spot tropical fish, and even sea turtles, just off the shore. For turtle sightings, keep an eye out in bays like Ao Leuk, Hin Wong, or even Tanote Bay. And if you’re hoping to see reef sharks, head to Shark Bay early in the morning and follow the rocky shoreline. They’re harmless, and seeing them glide through the water is unforgettable.

5. Beach Hopping & Hiking Trails in Koh Tao

Beach hopping in Koh Tao is a must. The island is small and surprisingly easy to explore, many beaches are within walking distance, and others can be reached by scooter or boat. Whether you’re chasing the best snorkeling spots or simply looking for a quiet place to lay your towel, there’s something for everyone. Freedom Beach, Mango Bay, and Shark Bay are some of the standouts, each with its own vibe and natural beauty.

If you’re short on time, booking a boat tour is a great way to hit multiple beaches in just a few hours. Most tours stop at remote bays you can’t access easily by land. But if you’re looking to avoid the crowds, try to head out earlier in the morning, around 9 – 10 AM, before the tours and day-trippers arrive.

For a more adventurous day, try hiking from Sairee Beach to Chalok Baan Kao or Freedom Beach. The trail winds past hidden gems like Jansom Bay, Sai Nuan Beach 1 & 2, and Tao Thong Villa, and ends at Chalok Bay or Freedom Beach, depending on your route. Expect about 3 hours of hiking, with time to stop at beaches along the way. Just note: some paths can be overgrown or even washed out, so it’s best to hike with a buddy and sturdy shoes. There’s also a 100 baht fee if passing through private resorts like Charm Churee to reach Jansom Bay.

Where to Stay in Koh Tao

There are plenty of great hotels on Koh Tao, ranging from luxury beachfront resorts to budget guesthouses and backpacker hostels. Most accommodations are fairly similar in terms of comfort and amenities, so it really comes down to where you want to base yourself.

If nightlife and convenience are high on your list, Sairee Beach is the most popular choice. It’s where you’ll find most of the bars, beach clubs, and restaurants. On the other hand, if you’re after a more tropical, laid-back vibe with better snorkeling opportunities and fewer crowds, Chalok Baan Kao Bay might be a better fit. Both areas are only about 15 minutes apart, so it’s easy to experience both even on a short stay.

How to Get to Koh Tao

Koh Tao doesn’t have an airport, so the only way to get there is by boat or ferry. The journey is part of the adventure, and thankfully, it’s fairly straightforward. You can depart from either Chumphon or Surat Thani on the mainland, or hop on a ferry from nearby islands like Koh Phangan and Koh Samui.

From Chumphon, fast ferries operated by Lomprayah depart at 7:30 AM and 1:00 PM, reaching Koh Tao in about 2 hours. If you’re coming from Surat Thani, ferries leave at 9:00 AM and 2:30 PM and usually take around 4–5 hours, including a land transfer from the Lomprayah office to the pier. Tickets can be booked easily through 12Go Asia, directly at the pier, or even through your hotel. Prices are around $40 AUD.

Some travelers also opt for the overnight ferry, which departs Surat Thani at 9:30 PM and arrives in Koh Tao around 6:00 AM the next morning, a great option if you’re looking to save on accommodation. The ferries are usually equipped with air conditioning, toilets, and basic snacks and drinks. If you’re prone to motion sickness, seas can get rough, so bring motion sickness tablets just in case.

Getting Around Koh Tao

There’s no public transport in Koh Tao, so getting around the island is a DIY experience, but that’s part of the adventure. You’ve got two main options: scooter rental or hotel transport.

Renting a scooter is by far the most popular and flexible way to explore. Expect to pay around 200–250 THB ($6–7.25 USD) per day. While the roads are mostly paved, some areas are still undeveloped and can be a bit tricky, especially after rain. If you’re not confident, just hop off and walk the rough patches.

Be cautious with rental shops asking to hold your passport as a deposit, motorbike scams, unfortunately, do happen. That said, trusted local names like Oli’s Motorbike Rentals and RPM come highly recommended.

Alternatively, many hotels offer scheduled or on- request transfers by truck or small van. Just ask the front desk for options, this can be a safer choice for those who prefer not to ride a scooter.

Whether you go by scooter or hotel shuttle, don’t skip exploring beyond the main beaches, some of Koh Tao’s most beautiful spots are tucked away inland or along rugged coastlines.

Best Time to Visit Koh Tao

Koh Tao has two main seasons: wet and dry. While much of Thailand enjoys its high season from November to February, the weather on Koh Tao tends to improve a little later. In fact, the best time to visit Koh Tao is between February and April, when the skies are mostly clear, the sea is calm, and visibility for snorkeling and diving is at its best.

That said, by mid-December, the weather usually starts improving, making it a decent time to arrive if you want to beat the holiday crowd. The island sees another busy period from July to September, especially among European travelers. Try to avoid coming in November, as it often brings persistent rain, a common mistake for first-time visitors expecting perfect beach days.
