Booking notes

Speedboat / catamaran · 30min–45min · ฿250–฿400

Thirty minutes. The choice that matters is which Samui pier you leave from — Bangrak is next to the airport, Nathon is the far side of the island from Chaweng.

Ferry · 1h–1h30 · ฿200–฿300

The vehicle ferries take twice as long as the catamaran for about ฿100 less, and they carry motorbikes — which is the actual reason to take one.

Speedboat / catamaran + Speedboat / catamaran · 3h–5h40 · ฿1,100–฿1,400

Koh Samui → Koh Tao: Lomprayah runs this one nearly alone. Children 3–11 travel at roughly half fare. In rough weather this crossing gets cancelled before the shorter Phangan hop does.

Koh Tao → Koh Phangan: The shortest of the three Gulf hops. Doing Samui to Tao with a Phangan stop costs about 2h30–3h in total and one extra ticket — which is why most people put Phangan in the middle rather than at the end.

Ferry + Ferry · 4h45–6h55 · ฿470–฿600

Koh Samui → Surat Thani: ฿200 is Raja's own published passenger fare on the Donsak–Lipa Noi crossing, one of the few numbers on this page that comes straight off an operator's board. Donsak pier is 60–90 minutes by road from Surat Thani town.

Surat Thani → Koh Phangan: ฿270 is Raja's published passenger fare for the Donsak–Thong Sala crossing. Around the Full Moon these sailings fill; book the day before rather than at the pier.

Flight + Bus + ferry (one ticket) · 14h45–18h50 · ฿2,900–฿8,000

Koh Samui → Bangkok: Bangkok Airways owns Samui airport and runs a near-monopoly on the route, so the floor here sits where other islands' ceilings do. Flying to Surat Thani and continuing by bus and boat is the standard way around it.

Bangkok → Koh Phangan: Two routings sell under the same name: the Chumphon catamaran down through Koh Tao, and the Surat Thani coach across to Donsak. The Chumphon version is faster and pricier; check which one the ticket actually is.

Bus + ferry (one ticket) + Bus + ferry (one ticket) · 23h45–30h30 · ฿1,500–฿2,500

Koh Samui → Bangkok: Standard coaches sit at ฿600–800 and VIP at ฿900–1,100, both including the Donsak ferry. One ticket means one company owns the connection — worth more on this route than the ฿100 difference between operators.

Both ends of the trip

Koh Samui

The Gulf's biggest island and the only one with its own airport.

Airport USM: Privately owned and served almost entirely by Bangkok Airways, which is why fares here sit well above the low-cost market.

Koh Samui is driest Feb–Aug and wettest Sep–Jan on its own monthly rain-day normals.

Koh Samui weather Koh Samui guide

Koh Phangan

Half an hour from Samui by boat: Full Moon on one beach, near-silence on the north coast.

Koh Phangan has no weather station of ours; the nearest one we track is driest Feb–Aug and wettest Sep–Jan.

Going the other way, or further

The return trip is on the Koh Phangan to Koh Samui page — fares are the same in both directions on almost every leg here, but the timetables are not. To string this hop into a longer trip with a pace check, use the route planner, and see the island comparison for which coast is dry in the month you are travelling.
