How Much Do Inter-Island Transfers Cost in Thailand (Ferries, Flights, Vans)?

The Real Price of Moving Between Islands

Inter-island transfers are an expense easy to underestimate in initial planning — but on a route with several islands, it can add up to a significant amount. Understanding the options in advance helps budget correctly.

Ferries

Usually the cheapest option — a ferry between Koh Samui and Koh Phangan, for example, costs around 300-400 baht ($9-12) one way. Longer ferries (like to Koh Lipe from Hat Yai) can cost more and take a few hours.

Combined Vans (Van + Ferry)

Packages combining a van ride + ferry (for example, straight from Bangkok to the island, no need to coordinate yourself) are convenient but more expensive than a single ferry — usually 500-900 baht, depending on distance. Especially worth it for those who don't want to deal with independent coordination.

Short Domestic Flights

Some islands (Koh Samui, Phuket) have a local airport — a short flight can cost 1,500-3,500 baht, much more than a ferry, but saves hours. Worth it mainly when time is short and the land/sea distance is large.

When Cheapest Isn't the Best Value

A cheap ferry that takes 5 hours instead of a 45-minute flight for an additional 2,000 baht — sometimes worth paying the difference to not lose a whole day of your vacation. Worth calculating this against the time remaining in your trip, not just against the single price.

Booking Tip

Ferry and van tickets can be booked in advance through local sites or through the hotel itself, usually at the same price or close to buying on-site — but they guarantee a spot, especially important in peak season when ferries fill up. Booking a day or two ahead is usually enough, no need to book weeks in advance.

Also worth checking if the hotel at your destination offers a pickup service from the ferry terminal — sometimes included free, and saves additional coordination with a taxi or tuk-tuk at the end of a long journey.

Multi-Island Route — How to Budget Correctly

On a route with 3+ islands (like Koh Samui-Koh Phangan-Koh Tao), reasonable to budget 1,500-2,500 baht for all accumulated transfers — a small number relative to the trip's overall budget, but worth planning for in advance and not assuming inter-island transfer is 'free' just because each single transfer is cheap.

General rule of thumb: the number of destinations in a route affects the transport budget more than total distance — three nearby islands still require three separate transfer payments, and sometimes cost more than one direct transfer for a longer distance.
