Koh Tao or Koh Phangan? Diving island, or party and yoga island.
The short answer: Koh Tao is small, about 21 km², and built around diving: it is one of the cheapest places in the world to learn, with dozens of dive schools around Sairee and Chalok Baan Kao. Koh Phangan is about six times bigger, famous for the Full Moon Party at Haad Rin, with a large yoga and wellness scene on the west coast and quiet bays in the north. Neither has an airport, and they are about an hour apart by boat.
Below: a side-by-side comparison, who each island suits, and how to travel between them.

Which one should you pick?
Choose Koh Tao if you want to dive or learn to dive, or spend your days snorkelling. It is small, so everything is close, though the hill roads are steep.
Choose Koh Phangan if you want more variety: the Full Moon Party or the Halfmoon Festival, a yoga retreat in Srithanu, or a quiet bay at the end of a long road.
Do both: they are about an hour apart, and many people combine them with Koh Samui on one trip through the Gulf islands.
Diving and snorkelling
Koh Tao is the reason many people come to the Gulf. Dive schools on the island have long kept prices low; in 2026 several of them listed the PADI Open Water course at around 10,000 to 12,000 baht, and the course takes three to four days. Training dives often start in the shallow bays around Koh Nang Yuan, just off the north-west coast.
Phangan has dive schools too, and its boats often visit the same sites, such as Sail Rock between the two islands. But on Tao, diving is the centre of island life, and it is easier to find a course that starts tomorrow.
Nightlife and the Full Moon Party
Phangan's Full Moon Party on Haad Rin is held about once a month. Entry is about 200 baht, paid in cash on the beach. The next dates listed by the organisers are 24 November, 24 December and the New Year countdown on 31 December 2026; see our Full Moon Party guide. The ticketed Halfmoon Festival runs about twice a month in Ban Tai.
Koh Tao's nightlife is smaller: beach bars along Sairee, and early nights for divers with a morning boat.
Beaches and where to stay
On Tao, Sairee on the west coast is the main beach, about 2 km long, with most of the bars and dive schools; Mae Haad is the pier village a short walk south; Chalok Baan Kao in the south is quieter. See where to stay on Koh Tao.
On Phangan, Thong Sala is the main town and pier, Haad Rin is the party beach, Srithanu and Haad Yao are on the quieter west coast, and Thong Nai Pan is in the north-east. See where to stay on Koh Phangan.
Getting there and around
Neither island has an airport. Koh Tao is closest to the mainland at Chumphon, where Lomprayah catamarans take about two hours and connect with trains and buses from Bangkok. Phangan is usually reached by flying to Koh Samui and taking a 20 to 30 minute boat, or by bus and ferry through Surat Thani.
Neither island has Grab. On Tao, taxis are expensive and the roads are steep and sandy, so it is a poor place to learn to ride a scooter; longtail boats work as water taxis. On Phangan, shared songthaews leave from Thong Sala, and the hill roads to Thong Nai Pan are steep.
Travelling between Koh Phangan and Koh Tao
Lomprayah, Seatran, Songserm and smaller speedboat companies sail from Thong Sala on Phangan to Mae Haad on Koh Tao every day. The fastest boats take about an hour; the slower ferry about two.
In the high season the morning boats can be crowded, so book a day or two ahead and arrive at the pier early. Rough seas between October and December can delay or cancel sailings.
Koh Tao vs Koh Phangan FAQ
Is Koh Tao or Koh Phangan better for diving?
Koh Tao. It has far more dive schools, low course prices and dive sites a short boat ride away. Phangan has dive schools too, but diving is not the centre of island life.
Is Koh Tao quieter than Koh Phangan?
Most of the time, yes, though Sairee has busy beach bars. Phangan is very busy around Haad Rin on Full Moon nights and quiet elsewhere.
How long is the boat from Koh Phangan to Koh Tao?
About an hour on the fast boats and about two hours on the slower ferry.
Does Grab work on Koh Tao or Koh Phangan?
No. Use taxis, songthaews, longtail boats or a scooter. Ask your hotel to arrange a pickup from the pier.
How do I get to Koh Tao from Bangkok?
The usual way is a train or bus to Chumphon and the Lomprayah catamaran, about two hours, to Mae Haad pier. You can also fly to Koh Samui and take a boat.
