Koh Samui, Koh Tao or Koh Phangan — which Thai island is for you?

Koh Samui, Koh Phangan and Koh Tao sit in a neat line in the Gulf of Thailand, with only a short ferry ride between each one. On a map they look like three versions of the same trip. They aren’t! Each island suits a different kind of traveler, and picking the right one (or the right two) makes a big difference to your trip. You can compare and book every leg right here on Ferryscanner. As always, you’ll pay the same price as booking direct, earn Ferryscanner Miles to put toward future trips, and enjoy round-the-clock support for your Thai adventure, courtesy of our Customer Service team.

Here’s the short answer:

• Koh Samui is the easy, comfortable choice. It has an airport, the widest range of hotels and restaurants, and beaches that work well for couples and families.
• Koh Phangan is two islands in one. The south has the Full Moon Party, and the north and west are quiet, slow and good for yoga and long beach days.
• Koh Tao is for divers and snorkelers. It’s small, social and laid-back, and it’s one of the most popular places in the world to learn to dive.

If you still can’t decide, you don’t have to. The three islands sit between 30 minutes and about 2 hours apart by boat, so it’s easy to combine them in one trip.

Who should choose Koh Samui?

Choose Koh Samui if you want comfort, choice and an easy arrival. It’s the only one of the three with an airport, so you can fly in from Bangkok in about an hour and be on the beach the same afternoon. That makes it the most practical pick for short trips and for families with young kids.

Samui’s beaches each have their own character. Chaweng is the busiest, with the most bars, restaurants and nightlife. Lamai is a little calmer but still lively. Bophut and its Fisherman’s Village have a relaxed, village-like feel and a popular Friday night market. Maenam and Choeng Mon are quieter and good for families who want calm water and fewer crowds.

Away from the beach, you can visit the Big Buddha temple, take a day trip to Ang Thong National Marine Park, or eat your way around the island’s night markets. The trade-off is that Samui is the most built-up and most expensive of the three. If you’re after a rustic, barefoot-bungalow feel, you’ll find more of it on the other two islands.

Who should choose Koh Phangan?

Choose Koh Phangan if you want either a big night out or a very quiet one, because the island does both.

The south of the island, around Haad Rin, is home to the Full Moon Party. Each month, thousands of people fill the beach for an all-night party, and there are smaller Half Moon and jungle parties in between. If that’s why you’re going, book your accommodation and ferry early. Boats and rooms fill up fast in the days around each full moon.

The rest of Koh Phangan is a different place. Srithanu, on the west coast, is known for yoga studios, healthy cafes and long stays. In the north, Bottle Beach and Thong Nai Pan feel remote, with soft sand and calm water. Many people come for the party and end up staying for the quiet side.

There’s no airport on Koh Phangan, so you’ll arrive by ferry, usually into Thong Sala pier. The ride from Koh Samui takes about 30 minutes to an hour, depending on the boat and pier, so many travelers fly into Samui and hop across.

Who should choose Koh Tao?

Choose Koh Tao if you want to spend time underwater. The island’s name means “Turtle Island,” and it’s one of the busiest places in the world to earn a scuba certification. Dive schools line Sairee Beach and Mae Haad, and an open water course usually takes three to four days. Courses here are also among the more affordable in the region.

You don’t need to dive to like Koh Tao. The snorkeling is easy to reach from shore at bays like Tanote and Aow Leuk, and a short boat ride takes you to Koh Nang Yuan, a trio of tiny islands joined by a sandbar with a popular viewpoint. Evenings are sociable but low-key, with sunset bars on Sairee Beach rather than big parties.

Koh Tao is small and hilly, and some roads are steep and rough. If you’re not confident on a scooter, use taxis or walk. It’s also the farthest island from the mainland, so the sea crossing can be choppy in the windier months (more on that below).

Koh Samui vs Koh Phangan: which is better?

Koh Samui is better if you want convenience, a wide choice of hotels and restaurants, and a short trip with no long transfers. Koh Phangan is better if you want the Full Moon Party or a slower, more rustic beach stay at a lower price.

For a lot of travelers, the answer is both. The islands are so close that you can base yourself on Samui and visit Phangan for a night or two, or spend most of your trip on Phangan and fly home via Samui. Ferries run several times a day from Samui to Koh Phangan, with Koh Samui to Koh Phangan ferries taking about 30 minutes to an hour.

Koh Phangan vs Koh Tao: which should you pick?

Pick Koh Phangan for parties, yoga and a wider variety of beaches. Pick Koh Tao for diving, snorkeling and a smaller, more close-knit island feel.

Backpackers often split their time between the two, since they’re the cheaper islands of the trio. The Koh Phangan to Koh Tao ferry takes about 1 to 1.5 hours on a high-speed boat.

Koh Samui vs Koh Tao: which matches your vibe?

Koh Samui suits travelers who want resort comfort, family-friendly beaches and easy flights. Koh Tao suits travelers who want to dive, snorkel and keep their budget down.

They’re the two islands farthest apart, but you can still get between them in a morning. Koh Samui to Koh Tao ferries take about 1.5 to 2 hours on a high-speed boat, and most stop at Koh Phangan on the way.

When is the best time to visit Koh Samui, Koh Phangan and Koh Tao?

The best time to visit all three islands is January to April, when the weather is driest and the sea is calmest. June to August is also good, which makes these islands a solid summer choice for UK travelers when Thailand’s west coast (Phuket, Krabi) is in its rainy season.

The Gulf islands get most of their rain from October to December, with November usually the wettest month. Expect heavy showers, rougher seas and the odd canceled ferry, especially on the longer crossing to Koh Tao. You can still visit at this time and prices are lower, but leave some flexibility in your plans.

Peak times for crowds and prices are Christmas to mid-January (summer vacation season for Australian travelers) and July to August. Book ferries and accommodation early if you’re traveling then, or around a Full Moon Party date.

How do you get to Koh Samui, Koh Phangan and Koh Tao?

You can reach all three islands by ferry from the Thai mainland, and Koh Samui also has its own airport.

• By air: Samui Airport has direct flights from Bangkok and a few other Asian hubs. Flights tend to be pricier than flying into Surat Thani on the mainland and taking a ferry.
• From Surat Thani (Don Sak pier): ferries run to Koh Samui in about 1.5 hours, as well as to Koh Phangan and Koh Tao. This is the main route if you’re coming from Bangkok by plane, train or bus.
• From Chumphon: high-speed boats run to Koh Tao in about 1.5 to 2 hours. This is the quickest way to reach Koh Tao from Bangkok overland.
• Between the islands: boats run several times a day in both directions between Samui, Phangan and Tao.

Can you visit all three islands in one trip?

Yes, and it’s one of the most popular island-hopping routes in Thailand. The islands sit in a line, so you can travel in one direction without doubling back.

A common plan looks like this:

1. Arrive via Chumphon and start on Koh Tao for diving or snorkeling (3–5 days).
2. Take the ferry south to Koh Phangan for a party or some quiet beach time (3–4 days).
3. Finish on Koh Samui for a few comfortable days (2–4 days) and fly out from Samui Airport.

You can also do the route in reverse, flying into Samui and leaving via Chumphon. Ten days to two weeks is enough to see all three without rushing. If you only have a week, pick two neighboring islands: Samui and Phangan, or Phangan and Tao.

When you’re ready to plan your route, you can compare times and prices and book your tickets on Ferryscanner, including the Koh Phangan to Koh Samui ferry for the last leg.
