Koh Phangan or Koh Tao? Two neighbouring islands in the Gulf of Thailand, less than two hours by boat from Koh Samui, with very different characters. The first is large and jungle-covered, with quiet beaches in the north and a real yoga culture. The second is small and rocky, and a well-known place to learn to dive. Here is how to choose, with prices checked in 2026, ferry routes and the right season.
In short: Koh Phangan for nature, Koh Tao for diving
Koh Phangan suits you if you want a variety of beaches, jungle hikes, waterfalls and yoga classes. The island has more than thirty beaches.
Koh Tao suits you if your goal is underwater: a try dive, a first certification or fun dives. The island is smaller and hillier, and life centres on Mae Haad (the pier), Sairee and Chalok Baan Kao. To compare with the country’s other islands, see which Thai island to choose.
Koh Phangan or Koh Tao for calm? Phangan beyond the Full Moon
Koh Phangan is known for the Full Moon at Haad Rin, in the south-east. But the rest of the island moves at a different pace, especially in the north and west. Mr Schaka suggests staying away from Haad Rin if you want peace and quiet.
- Haad Salad and Haad Yao (north-west): two sheltered bays. Haad Salad, small and quiet, is popular with families.
- Mae Haad: a sandbank links the beach to the islet of Koh Ma, which you can walk to depending on the tide.
- Chaloklum: a fishing village on the north coast and the departure point for boats to Bottle Beach.
- Thong Nai Pan Yai and Noi (north-east): two neighbouring bays, Noi more upmarket, Yai simpler and more relaxed.
For jungle, part of the island is protected as Than Sadet National Park. Phaeng Waterfall, a few kilometres north of Thong Sala, and the Domesila viewpoint just above make an easy half day. The sportier can climb Khao Ra, the island’s highest point (627 m), on a 2 to 3 hour forest hike: start early, carry water and ideally go with a guide.
Yoga is centred on Srithanu, on the west coast, with many studios and meditation centres; classes cost around 300 to 500 THB.
Bottle Beach, the beach at the end of the island
Bottle Beach (Haad Khuad) is a sandy bay on the north coast, backed by jungle, with a few bungalows and simple restaurants. There is no proper road. You get there by longtail boat from Chaloklum or Haad Khom: 15 to 30 minutes, roughly 150 to 400 THB per person each way depending on the number of passengers. Another option is a trail of about 1.5 hours from Haad Khom, hot and steep in places.
Good to know: there is no ATM at Bottle Beach, so bring cash. Agree on a return time with the boatman: the last boats leave in the late afternoon, around 5 pm.
Koh Tao and diving: try dive, Open Water and dive sites
Koh Tao has a great many dive centres. Ranges checked in 2026, to confirm with your chosen centre:
- Try dive (Discover Scuba Diving or Try Dive): about 2,500 to 3,500 THB, no certification needed, with an instructor.
- Open Water (entry level, PADI or SSI): about 11,000 to 12,500 THB over 3 to 4 days: theory, shallow-water skills, then open-water dives. Open to children from 10 as a junior certification.
- Fun dives (certified divers): about 800 to 1,200 THB per dive including gear, cheaper in packages.
Beginners often dive at Japanese Gardens, a sheltered bay off Koh Nang Yuan (2 to 18 m) or at Twins, two rocks covered in anemones. With more experience, divers head to Chumphon Pinnacle and Sail Rock, granite pinnacles visited by barracuda and sometimes whale sharks, or to the wreck of HTMS Sattakut, a Thai navy ship sunk in 2011 as an artificial reef.
Good to know: before any course you fill in a medical questionnaire. Asthma, a heart or lung condition, recent surgery: talk to your doctor before you travel, as medical clearance may be required. Mr Schaka lives with interstitial pulmonary fibrosis linked to rheumatoid arthritis; his tips are gathered in travelling in Thailand when you are short of breath.
Koh Nang Yuan, three islets joined by sand
Just north-west of Koh Tao, Koh Nang Yuan is made up of three islets linked by a white sandbar. About ten minutes of steps lead to the viewpoint over the islets and the strip of sand. The island belongs to a private resort and charges an entrance fee in cash: between 100 and 250 THB according to recent sources, to check on the spot. A longtail from Sairee takes about 15 minutes.
- Plastic bottles are banned and bags are checked on arrival: bring a refillable bottle.
- Fins and water shoes are not allowed; a mask and snorkel are enough for Japanese Gardens.
- Come early in the morning or late in the afternoon to avoid the crowds.
Getting to Koh Phangan and Koh Tao from Koh Samui or Chumphon
Neither island has an airport, so you arrive by boat. The easiest way is via Koh Samui, which has its own airport (see our complete Koh Samui guide), or via Chumphon on the mainland.
- Koh Samui → Koh Phangan: 20 to 60 minutes depending on the boat, about 200 to 500 THB. Most boats dock at Thong Sala; the Haad Rin Queen runs from Big Buddha pier to Haad Rin.
- Koh Samui → Koh Tao: about 1 h 30 to 2 h 45, often stopping at Koh Phangan (Lomprayah, Seatran, Songserm and others).
- Chumphon → Koh Tao: Lomprayah catamaran, about 1 h 45 to 2 h 30, a few departures a day. Chumphon is reached from Bangkok by train, bus or plane (about a 1-hour flight).
In high season, book the day before. Leave a margin before a flight: in rough seas, crossings can be delayed or cancelled. Timetables and fares change often, so check before you go.
When to go to Koh Phangan and Koh Tao
Both islands follow the Gulf of Thailand climate, which differs from Phuket and the Andaman Sea. The driest period usually runs from February to September. Heavy rain arrives in late October and can last into December, peaking in November: rough seas, reduced underwater visibility and occasional boat cancellations.
For diving, February to May often brings the best visibility and the calmest seas; it is also when whale sharks are most often seen, with no guarantee. September and October, before the monsoon, are often calm too.
Frequently asked questions
Can you visit Koh Phangan and Koh Tao on the same trip?
Yes. Boats between Koh Samui and Koh Tao often stop at Koh Phangan. Allow at least three days on each island, more if you take the Open Water course.
Do you need to swim to dive on Koh Tao?
For a try dive, you need to be comfortable in the water. For the Open Water course, centres ask for a short swimming and floating test at the start.
Is Koh Phangan quiet outside the full moon?
Yes, most beaches in the north and west stay quiet all year. Haad Rin gets busy around the full moon: stay elsewhere on those nights if you want calm.
The book
Koh Phangan and Koh Tao are neighbours of Koh Samui and Ang Thong Marine Park, where The Season of Breath takes place. Mr Schaka’s novel follows a journey through Thailand with pulmonary fibrosis, from Bangkok to the Gulf. Available in English.
