Koh Samui and Koh Phangan sit twenty minutes apart by fast boat, and they suit different trips. Samui has an airport, a ring road with traffic and beach clubs with reservation lists. Phangan has yoga schools, dirt tracks to empty bays and one town where the party happens. The crossing is short and cheap, so the main decision is where to sleep.
The short version of each island
Samui is Thailand’s second-largest island after Phuket and works like a resort town wrapped around a mountain. Chaweng is the long, busy beach with the nightlife, and Lamai is the calmer one to its south. Bophut’s Fisherman’s Village has turned an old fishing settlement into restaurants looking across to Phangan, and Maenam is the quiet, cheaper stretch.
On Phangan, Thong Sala, where the ferries arrive, is a working town rather than a sight. Haad Rin, in the far south, hosts the Full Moon Party. The yoga schools, retreat centres and vegan cafes are on the west coast around Srithanu. The northeast bays, Thong Nai Pan Noi and Yai, are the island’s upmarket corner, and Bottle Beach is reached by longtail boat, on foot, or by 4x4 songthaew down the track for about 100 baht a head.
Flights, buses and ferries
Samui’s airport is owned by Bangkok Airways, and with little competition, round trips from Bangkok often cost two or three times what other domestic routes do. The flight takes 65 minutes and the runway is ten minutes from Chaweng.
Phangan has no airport. Everyone arrives by boat, usually via Samui or the mainland pier at Donsak. From Bangkok, the overnight bus-and-ferry combination costs from about 1,400 baht and takes 10 to 14 hours, and the sleeper train to Surat Thani with a bus-and-ferry connection is sold as one ticket for roughly 875 to 1,575 baht. The cheaper way to fly is to Surat Thani on a low-cost carrier, then the bus and ferry.
Lomprayah catamarans cross from Nathon and Maenam in 20 to 30 minutes for 300 to 400 baht. Seatran Discovery goes from Bangrak in 30 to 45 minutes for around 330 to 370 baht. Raja Ferry is the slow one from Lipa Noi, about an hour and a half from roughly 130 baht, and the only one that takes vehicles. All three arrive at Thong Sala. The Haad Rin Queen runs from Bangrak straight to Haad Rin, which saves the drive across Phangan on party nights; booking sites list several sailings a day at 250 to 350 baht.
Public transport is thin on both islands. Samui has shared songthaews on the ring road by day, plus taxis and Grab. On Phangan most visitors rent a scooter, and the roads to the northeast bays are steep.
The Full Moon Party
The party runs on Haad Rin’s Sunrise Beach once a lunar month, from 9pm until well past dawn, with an entry fee of about 200 baht at the beach gate. Dates move around Buddhist holidays. The next are 26 September, 27 October (moved a day for the end of Buddhist Lent), 24 November and 24 December, with a New Year countdown party on 31 December. Confirm the date before booking anything non-refundable.
The party stays in Haad Rin. Stay in Srithanu or the northeast and you can spend a month barely aware of it. If the party is why you are coming, stay in Haad Rin itself; Samui-based partygoers cross by speedboat and come back at dawn, paying party prices both ways.
What each island costs
Phangan is the cheaper island. BudgetYourTrip’s traveller averages put a day at about $60 a person on Phangan against $78 on Samui, with two people sharing a room. The gap is widest at the bottom end, where Phangan still has beach bungalows that Samui has mostly built over. Dorms cost $8 to $15 on either island. At the top end, $120 a night on Phangan’s northeast coast often buys a better setting than the same money on Samui’s east coast.
On Samui the choice of beach is between Chaweng’s noise and Maenam’s calm; on Phangan, between Haad Rin’s party radius and the quieter west coast. The map view on Booking.com shows which beach a hotel sits on.
When to go
Both islands sit in the Gulf and share a calendar: driest and calmest from February to April, and decent from January through August. October to December bring half the year’s rain, and November alone averages about 445 mm on Samui, so ferries run late or rough. The regional weather guide explains why the Gulf runs opposite to Phuket, which is why these islands suit a mid-year trip.
Doing both
Five days split three and two works: Samui first for the comfortable stretch and Phangan for the slower one, or the reverse if you want to end near an airport. Buy the ferry ticket a day ahead in high season, carry small notes for the pier porters, and count the crossing as half a day once transfers are included. Koh Tao, the diving island, is about an hour further north from Phangan by fast boat.
