Ecotourism in Koh Mak

Koh Mak is a small island outside Koh Chang archipelago, only 16 square metres and 80% of Koh Mak is owned by five local families who carefully manage its development and ensure its business remains exclusively local. The community made a pledge to follow ecotourism principles and develop the island in a sustainable manner, working with nature and not against it.

The island’s focus on ecotourism and low-carbon philosophy is evident in its extensive biking trails. Koh Mak is relatively a flat island where cycling is fun for everybody. 

The community strives for ways to reduce the environmental impact. On the island, the locals are farming and harvesting locally grown food, organising beach clean ups, having locally owned stores instead of big franchises on every corner are examples of attempts to preserve the charm of this island.

On top of promoting renewable energy, recycling and efficient use of water, the aim is to foster sustainable tourism by embracing traditional ways of life and fighting against the larger resorts to establish on the island.

The locals have agreed on a set of rules, which include the prohibition of foam packaging, the discouragement of engine-powered water sports like jet skis and banana boats, avoidance of agricultural chemicals and a ban on 24-hour convenience stores.
