Island comparison

Koh Mak vs Koh Kood

Two neighbouring islands in Trat province, both reached from Laem Sok pier — but they suit different trips. Here is the honest comparison: size, beaches, sport, diving, food, boats and what you actually pay.

Short answer

Small and active, or large and resort-led

Pick Koh Mak for a small, flat island you can cycle end to end in two hours, family-run stays, lower prices and a genuine sports scene — Muay Thai, tennis, pickleball, yoga and diving. Pick Koh Kood if you want a much larger island with big resorts, waterfalls and widely spaced bays, and you are happy to pay more and use transport between beaches. The nature on Koh Kood is definitly beautiful. 

Side by side

How the two islands differ

TopicKoh MakKoh Kood
Size & feel16 km², flat and easy to cycle. One connected village community, family-owned resorts, no 7-Eleven by choice. Small enough that you recognise faces after two days.About 105 km² and hilly, spread over distant bays. More resorts overall, including large five-star properties, but bays feel separate and you rely on transport between them.
BeachesLong shallow bays: Ao Kao for sunsets, Ao Suan Yai for the widest sweep, Ao Nid for sunrise and the pier, plus the sandbar crossing to Koh Kham.Bigger, deeper-water beaches such as Klong Chao and Ao Tapao, with waterfalls inland. Sand is excellent, but distances between beaches are much greater.
Sport & trainingThe unusual part: a Muay Thai camp, tennis courts, pickleball, fitness gyms, beachfront yoga, cycling and running routes, plus stay-and-train packages.Mostly resort-based activities — kayaking, snorkelling trips, spa and waterfall hikes. No comparable training scene.
Diving & snorkellingDive centre on the island with day trips to the Koh Rang marine park; Koh Kham and Koh Rayang reefs are minutes away.Also reaches Koh Rang, usually as a longer boat trip. Good, but Koh Mak sits closer to the park.
Food & nightlifeLocal kitchens, beach bars and cafés at village prices; evenings are quiet and end early.More resort dining and higher average prices; nightlife is equally low-key.
Getting thereSpeedboat or car ferry from Laem Sok pier near Trat, roughly 45–90 minutes depending on the boat.Speedboat from Laem Sok too, usually a longer crossing — many services call at Koh Mak on the way.
BudgetWide range from island huts to villas, with genuine long-stay and solo-traveller rates when you book direct.Skews higher: strong luxury segment, fewer cheap independent options.
Practical notes

Doing both on one trip - stay minimum 5 nights on Koh Mak

  • Different gateways: Koh Kood leaves from Laem Sok pier near Trat only. Koh Mak leaves from Laem Ngop (faster and no crowds) and also from Laem Sok (Boonsiri only) — see the Koh Mak ferry and speedboat timetable and the route from Bangkok.
  • Island hop: many speedboats call at Koh Mak first, so Koh Mak to Koh Kood is a short leg. Split minimum five nights each, rather than island-hopping, instagram-motivated day-tripping. Stay longer with a purpose. 
  • Season doesn't matter for the islands: check the best time to visit — green-season boats are reduced for both.
  • Getting around on Koh Mak: bicycles and scooters cover the island; see getting around Koh Mak. On Koh Kood, you will need transfers between bays and from your resort.
