First, get a feel for the rhythm of Koh Mak. This island isn't built for fast travel β boats run only a few times a day, supplies on the island are limited, and a lot of things shut down during the monsoon. So a good plan leaves room for travel time and doesn't cram in so many activities that you end up worn out. Two days and one night is just enough to get on the beach, cycle around the island, and do one snorkeling trip, without rushing.
Before you go: boats, prices, and what to pack
You reach Koh Mak by boat from the Trat mainland. The main departure points are Laem Ngop Pier (Krom Luang) and Laem Sok Pier. A speedboat takes around 50 minutes, while Boonsiri's fast catamaran takes about an hour. Prices run roughly as follows (double-check with the operator before you travel, since schedules and fares change with the season).
- Speedboat from Laem Ngop (Panan / Leelawadee / Suansuk / Seatales) β around 50 minutes, about ΰΈΏ450/trip, with several departures during high season from late morning to afternoon
- Boonsiri boat from Laem Sok β air-conditioned catamaran, around 1 hour, about ΰΈΏ400/trip, one departure a day
- Slow boat β around 3 hours, about ΰΈΏ200, the cheapest option but slow and with few departures
- Each speedboat docks at a different beach (Ao Kao / Ao Nid / Makathanee), so pick the departure that lands closest to your accommodation
Cash really matters here
Things on the island cost more than on the mainland, and many shops take cash only. There are few ATMs on the island and they sometimes run out of money. Withdraw enough on the Trat mainland to cover the boat, accommodation, bike/kayak rental, the snorkeling trip, and every meal.
Avoid the monsoon season
May to October is the rainy season on the Trat coast, with rough seas and far fewer boat departures. Many snorkeling trips and inter-island boats stop running. If you have your heart set on snorkeling at Koh Kham, go between November and April, and check the forecast before every boat departure.
Book the activities in your Koh Mak trip ahead
Booking online ahead on Klook or GetYourGuide is usually cheaper than the gate and skips the queue. Pick only the experiences you actually want β prices and availability are shown live on each site.
Day 1 β Land at Ao Kao Beach + cycle the island
Arrive, hit the beach, then cycle around
Cycling around the island takes about half a day at an easy pace, and stretches longer if you stop often for photos and rest. The appeal isn't the distance β it's the quiet atmosphere along the way: shady trees, coconut groves, and the sea appearing in glimpses. If cycling isn't your thing you can rent a motorbike, but a bike fits the rhythm of the island far better.
Travel light on the island
Koh Mak positions itself as a low-carbon island, and waste management here is limited. Bring your own water bottle, skip single-use plastic, and carry your trash back to dispose of it properly. It helps keep the beaches nice for the next person.
Day 2 β Snorkel at Koh Kham, then head back to the mainland
Koh Kham is a small island off the Ao Suan Yai side of Koh Mak. Its draw is the white sand set against dark rocks, clear water, and shallow coral you can snorkel over. You can get there two ways β kayak from Ao Suan Yai (close enough to paddle if the sea is calm), or buy a snorkeling boat trip sold as a package. There's a landing fee of about ΰΈΏ200/person.

Have a weather backup plan
The snorkeling trip depends entirely on the wind and waves. If the weather turns bad on the second morning, the dive shop may cancel. Have a backup ready β switch to kayaking near shore, walk the beach, or cycle to the spots you didn't reach on day one.
Rough cost summary per person
- Return boat fare β around ΰΈΏ800β900 (speedboat ΰΈΏ450/trip / Boonsiri ΰΈΏ400)
- 1 night's accommodation β from a few hundred to a few thousand baht a night, depending on the resort
- Bike rental β a few hundred baht a day; ask at your resort or a rental shop
- Kayak β around ΰΈΏ150/hour or ΰΈΏ500/day
- Snorkeling trip / Koh Kham landing fee β landing fee about ΰΈΏ200/person; the snorkeling trip is a separate package
- Food β slightly higher than the mainland; budget a few hundred baht per meal
These figures are estimates from operator information at the time of writing. Real prices shift with the season and the operator. Before you go, call ahead to confirm the boat schedule, accommodation, and snorkeling trip β especially if you're traveling at the start or end of the season when the weather is borderline.
