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

Bus · 3h–4h20 · ฿200–฿400

The overland link between the Gulf and Andaman coasts. Sold as part of most Samui-to-Krabi combined tickets rather than bought on its own.

Bus + ferry (one ticket) + Ferry · 9h15–13h10 · ฿1,000–฿1,550

Krabi & Ao Nang → Koh Samui: Ferry to Donsak, coach across the peninsula, arrive Krabi in the late afternoon. It's the standard way to swap coasts without flying, and it eats a full day whichever operator sells it.

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.

Flight + Day train · 10h45–13h45 · ฿1,328–฿3,628

Krabi & Ao Nang → Bangkok: Usually a little cheaper than Phuket and much closer to Ao Nang, Railay and the Lanta and Phi Phi piers. If the Andaman islands are the plan rather than Patong, this is the better arrival.

Bangkok → Surat Thani: Air-conditioned 2nd class seats, about 9 hours in daylight. Cheaper than a sleeper but it costs a full day rather than a night.

Both ends of the trip

Krabi & Ao Nang

Limestone cliffs, Railay's climbing beaches and the pier for Phi Phi and Lanta.

Airport KBV: Cheaper than Phuket on most Bangkok routes and closer to Railay and the four-island boats.

Krabi & Ao Nang is driest Nov–Apr and wettest May–Oct on its own monthly rain-day normals.

Surat Thani

Not a destination — the mainland interchange every Gulf island ticket routes through.

Airport URT: The cheap way into the Gulf islands: low-cost flight here, then a bus-and-ferry combination to the pier.
