Ko Mak is 16 square kilometres of coconut plantation, rubber trees, and coral reef, and roughly 95% of people who visit Koh Chang have never heard of it. That percentage is the best thing about Ko Mak. The island doesn't have a resort strip or a beach club or a road that circumnavigates it โ it has coconut palms, calm turquoise water, some of the healthiest coral in the eastern Gulf, and a pace of life that makes 3pm feel approximately equivalent to 10am. For travellers who have done the Gulf circuit (Samui, Phangan, Tao) and want something that doesn't require choosing between "beaches" and "somewhere interesting," Ko Mak is the correct answer.
Beaches and Snorkelling in Ko Mak 2026
Ao Kao on the south-west coast is Ko Mak's longest and most beautiful beach - a shallow, calm bay with excellent snorkelling off the rocky headlands at either end. The coral directly off Ao Suan Yai beach on the north-west is some of the healthiest in the eastern Gulf. Book a Ko Mak snorkelling tour to the surrounding islands of Ko Kham and Ko Rayang - these offshore islands are protected and home to extraordinary marine life.
Exploring the Island
Ko Mak is 16 square kilometres of coconut plantation, rubber trees, and mangrove - walkable and cyclable without the traffic that plagues larger Thai islands. The interior is genuinely beautiful, particularly in the early morning when the light filters through the coconut palms. Rent a bicycle or book a guided island tour - the island's quiet roads make cycling an absolute pleasure.
Where to Stay in Ko Mak 2026
Ko Mak's accommodation skews toward boutique guesthouses and small resorts rather than large international brands - reflecting the island's character. Koh Mak Resort on Ao Suan Yai beach is the longest-established and most reputable property. Lazy Day Beach Resort on Ao Kao is more intimate, with excellent snorkelling from the beach. Book Ko Mak ferry transfers from Trat and Koh Chang - regular services operate in season.
