Our pick for budget

Speedboat / catamaran

฿500–฿650 · 45min–1h10 · Lomprayah High Speed Ferries

Same option twice: on this pair the quickest way is also the cheapest, which is rarer than it sounds — it usually means one operator has the route to itself.

Booking notes

Speedboat / catamaran · 45min–1h10 · ฿500–฿650

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 · 3h–3h40 · ฿550–฿700

Three hours-plus against the catamaran's hour, for roughly the same money. It exists mainly as the fallback when Lomprayah is full.

Speedboat / catamaran + Speedboat / catamaran · 2h45–5h15 · ฿850–฿1,150

Koh Tao → Koh Samui: 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 Samui → Koh Phangan: 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.

Speedboat / catamaran + Ferry · 3h15–6h · ฿800–฿1,050

Koh Tao → Koh Samui: 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 Samui → Koh Phangan: 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 + Ferry · 6h15–9h35 · ฿1,070–฿1,550

Koh Tao → Surat Thani: Nothing runs Surat Thani to Koh Tao directly — the boat calls at Phangan or Samui on the way, which is why the time band is so wide. Coming from Bangkok, Chumphon is the shorter door.

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.

Bus + ferry (one ticket) + Bus + ferry (one ticket) · 25h45–30h50 · ฿1,750–฿2,650

Koh Tao → Bangkok: The bus runs overnight to Chumphon and hands over to the 08:00 catamaran, landing on Koh Tao around 10:30 — 12 to 13 hours door to door. Lomprayah's own promoted fare for the combination was ฿850 in May 2026; the top of the band covers VIP coach seats and high season.

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.
