Koh Kood sits near the Cambodian border, about as far east as Thailand’s islands go, and reaching it from Bangkok is a full day’s travel. That distance is exactly why the island is still quiet. This guide covers the three realistic ways to make the trip, and the one timing rule that decides everything.
Prices are in Thai baht (THB) with US dollars in parentheses at ฿33 = US$1 (July 2026). Sources are linked at the bottom.
Quick comparison
| Route | Duration | Rough price | Notes |
|---|---|---|---|
| Boonsiri combined bus + ferry | 7-8 hours | ~฿850 (US$26) | The standard option, one ticket |
| Suvarnabhumi Airport direct | 7-8 hours | Varies | New since 15 Jan 2026, includes a meal |
| Fly to Trat + ferry | 3-4 hours | Considerably more | Bangkok Airways only |
The rule that decides your day: the last ferry is 14:20
Before anything else, understand this. Ferries from Laem Sok Pier to Koh Kood leave at 10:45 and 14:20. There is no evening crossing. Miss the 14:20 and you are sleeping in Trat.
So plan backwards from the boat, not forwards from Bangkok. Everything below follows from that.
Boonsiri combined ticket: the standard route
Boonsiri sells a single ticket covering both legs, which is what makes this journey manageable:
- VIP bus from Bangkok — departures at 05:00 and 08:00
- High-speed catamaran from Laem Sok Pier — departures at 10:45 and 14:20
Total time is 7 to 8 hours, at around ฿850. The 05:00 bus connects to the 10:45 boat; the 08:00 bus connects to the 14:20.
The value here isn’t just the price — it’s that the connection is Boonsiri’s problem rather than yours. If the bus runs late, the ferry is theirs too. Booking the legs separately to save a little money means carrying the risk of watching the last boat leave without you.
New in 2026: direct from Suvarnabhumi
Since 15 January 2026, Boonsiri has run a direct service from Suvarnabhumi Airport (BKK) to Koh Kood, combining bus and ferry on one ticket with a packed meal included.
If you’re flying into Bangkok internationally and Koh Kood is the destination rather than a stop, this is the cleanest option available. You skip central Bangkok entirely — no transfer into the city, no overnight, no separate connection to a bus terminal at 04:30.
Flying to Trat: the fast option
Bangkok Airways flies Bangkok to Trat Airport in about an hour, and it’s the only carrier on the route, so fares reflect that. The morning service (PG301) is timed to connect with the 10:45 ferry, which is the whole point — take a later flight and you’re gambling on the 14:20.
Door to door this is roughly 3-4 hours including the airport-to-pier transfer, against 7-8 by road. If you’re short on days rather than money, it’s the obvious upgrade.
What to expect at the other end
Koh Kood is Thailand’s fourth-largest island and among its least developed. There’s no real nightlife, limited infrastructure, and the beaches are quiet in a way that most Thai islands stopped being years ago. Resorts are spread out and there isn’t much between them, so pick where you stay carefully — you won’t be casually wandering to the next bay.
The journey is the price of admission, and it’s the reason the island is what it is.
Which should you pick?
Flying into Bangkok internationally: the Suvarnabhumi direct service. Straight from arrivals to the island on one ticket.
Already in Bangkok, watching the budget: the 05:00 Boonsiri bus to the 10:45 ferry. ฿850 and you’re on the beach mid-afternoon.
Short on time: Bangkok Airways to Trat on PG301, connecting to the 10:45 boat.
Whichever way you go, book the ferry leg first and fit everything else around it.
