TL;DR: Three types of boat run from Koh Chang to Koh Mak and Koh Kood: the year-round Boonsiri high-speed catamaran ferry, plus seasonal speedboats and wooden boats that only run in high season (1 November to 30 April). To Koh Mak, expect departures around 9:00am and 12:00-12:30pm for roughly ฿500-900 (about US$15-27) depending on boat type, with the crossing taking about 1-2 hours. To Koh Kood, the same departure windows apply but prices run higher, roughly ฿700-1,200 (about US$21-36), since it’s the farther island. From May to October, only the Boonsiri ferry keeps running daily; the speedboat and wooden boat options stop for the low season. Hotel-to-pier transport on Koh Chang and pier-to-hotel transport on arrival are included in the ticket price. All prices ฿33 = US$1 (July 2026).
Koh Mak and Koh Kood sit south of Koh Chang in the same Trat island chain, quieter and less developed, and a lot of Koh Chang visitors add one or both as a side trip or a final stop before flying home. Getting there means picking between a proper high-speed ferry and a couple of seasonal, smaller boats, and which one makes sense depends heavily on when you’re travelling. This guide breaks down every option, the price difference between Koh Mak and the farther Koh Kood, and what changes outside high season, checked against current 2026 Koh Chang ferry operator timetables.

Which boat should you book?
The Boonsiri high-speed ferry is the safest year-round default: a proper 200-seat catamaran that runs daily regardless of season, at a mid-range price between the cheaper wooden boat and the pricier speedboat. If you’re travelling outside high season (May to October), this is your only option, so it’s worth knowing the schedule even if you’d otherwise consider one of the seasonal alternatives.
If you’re travelling in high season (1 November to 30 April) and want the cheapest fare, the Bangbao wooden boat is the budget pick, at roughly ฿500 (about US$15) to Koh Mak, though it’s the slowest option and takes closer to 2 hours on the water. The Kai Bae and Bangbao speedboats are the fastest but priciest options, useful if you want to minimise time on the water and don’t mind paying more for it.
How the Koh Kood route differs
Koh Kood sits farther south than Koh Mak, and every boat type reflects that in both price and duration. Where the Koh Mak crossing runs about 1 hour on the ferry or speedboat, Koh Kood takes closer to 1.5 hours on the Boonsiri ferry and up to 3 hours on the wooden boat. Prices scale up accordingly, roughly ฿700-1,200 (about US$21-36) one-way compared with Koh Mak’s ฿500-900 (about US$15-27). If your itinerary includes both islands, note that inter-island boats also run between Koh Mak and Koh Kood directly, so you don’t necessarily need to route back through Koh Chang between the two.
Seasonal availability: what changes May to October
Only the Boonsiri ferry operates in low season. From 1 November to 30 April, all three boat types run, giving you the full range of price and speed options. From May to October, the smaller speedboat and wooden boat services stop, typically winding down by the end of April or in early May depending on demand and sea conditions, and don’t resume until the following November. If you’re planning this crossing in the wetter months, build your itinerary around the Boonsiri ferry’s schedule rather than assuming every option in the tables above will be available.
Which pier do you leave from?
Most departures, including the Boonsiri ferry and both Bangbao boat services, leave from Bang Bao pier, on Koh Chang’s southwest coast. The Kai Bae speedboat departs from Kai Bae pier, further north. Ticket prices include hotel-to-pier transport on Koh Chang, so you don’t need to arrange your own transfer, and the same applies in reverse: pier-to-hotel transport is included on arrival at Koh Mak or Koh Kood.
Honest downsides
This is a well-run route, but it has real limitations. Only two departure windows a day, roughly 9:00am and 12:00-12:30pm, means there’s no flexibility for a late-afternoon crossing; miss both and you’re staying another night on Koh Chang. The seasonal boats disappear for half the year, so anyone travelling May to October has effectively one operator and one boat type to choose from. The wooden boat is slow, and while it’s the cheapest option, the extra time on the water isn’t for everyone, especially on the longer Koh Kood run. And conditions do get choppier in the shoulder months, so if you’re prone to seasickness, favour the larger Boonsiri ferry and an early sailing over a smaller speedboat.
Bottom line
For most travellers, the Boonsiri high-speed ferry is the easiest, most reliable choice year-round, with the seasonal speedboat and wooden boat options worth considering only if you’re travelling in high season and have a specific reason to want the cheaper or faster alternative. Book a day or two ahead in high season, confirm which pier your ticket departs from, and remember Koh Kood costs more and takes longer than Koh Mak on every boat type.
