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 โ 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 โ a ferry between Koh Samui and Koh Phangan, for example, is usually a relatively cheap option, and prices vary by company and season. 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 โ the price depends on distance and company. 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 โ a short flight is usually much pricier 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 short flight that costs more โ 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 โ 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 โ sometimes included free, and saves additional coordination with a taxi or tuk-tuk at the end of a long journey.
Multi-Island Route โ How to Budget Correctly
On a route with 3+ islands (like Koh Samui-Koh Phangan-Koh Tao), worth budgeting for all the accumulated transfers โ usually a small amount 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 โ three nearby islands still require three separate transfer payments, and sometimes cost more than one direct transfer for a longer distance.
Season and sea: when crossings are less reliable
In the rainy season the sea can be stormy, and ferries are sometimes canceled or delayed. So do not book a return flight on the morning after a sea crossing, and leave a buffer day. Book tickets in advance in peak season, and check the provider's cancellation policy. Details on water safety are in the water safety guide and on the season in the rainy season guide.
Gulf of Thailand versus the Andaman Sea
The islands in the gulf and in the Andaman are on different coasts, so moving between them usually requires a long overland trip or a flight. Do not assume you can hop from Samui to Krabi easily. Choose one region for your route, unless you are willing to invest time in the transfer. The comparison between the coasts is in the east vs west coast islands guide. Route ideas are in the southern islands itinerary and the gulf islands itinerary.
Slow ferry or speedboat
A regular ferry is usually cheaper and more comfortable but slower, while a speedboat saves time but is less comfortable for anyone prone to seasickness. The price varies by company and route, and it is worth comparing. Also check whether there is room for luggage and whether the price includes a transfer from the pier. A detailed comparison is in the ferries and speedboats guide. Details on flights are in domestic flights in Thailand.

Beyond the ticket itself there are side costs: a taxi or tuk-tuk to the pier, small fees on some islands, a longtail boat to a beach without a pier, and sometimes a surcharge for large luggage. Include these in your budget so the total does not surprise you. If your hotel offers a transfer, ask what the price is. Places to stay in Samui are on the Koh Samui hotels page.
Planning connections between transports
A route that combines a bus, a ferry, and a flight needs time buffers. Add at least a few hours between a ferry and a flight, and do not rely on a schedule shown in the past. It is advisable to confirm the times a few days before travel. For overall route planning use the trip itinerary and the budget calculator.
To save, consider buying a combined ticket that links several segments, but compare it with the price of each segment separately. Also check whether there is a discount for booking in advance or for multiple passengers. It is important to read the cancellation and change terms, because they vary between companies and routes.
Finally, always keep a backup: if a ferry is canceled, check whether you can switch to a different time or provider. That way you avoid losing a whole day.
