Koh Mat Lang is a hidden gem located near Son Cape, just a few hundred meters from Chaweng Beach. Despite being close to a bustling tourist area, the atmosphere on the island is quiet and private. The side facing Samui has a small sandy beach and crystal-clear water, perfect for relaxing and swimming.

The highlights here are kayaking and SUP boarding, which can be easily paddled from the north side of Chaweng or Son Cape. Once you reach the island, you can snorkel and admire the vibrant shallow coral reefs and colorful schools of fish, especially in the eastern and northern parts of the island.

Another important highlight is the “Low Tide Land Bridge” phenomenon. On days with very low tides, a strip of rocks and sand connects the island to the mainland. Some tourists can walk across the water, adding a unique adventure experience.

In addition, Koh Mat Lang offers a beautiful panoramic view of the Chaweng Bay curve. You can see the long stretch of beach and the view of airplanes taking off and landing at Samui Airport against the sea, a rare photo opportunity.

Since the island has no buildings or electricity, the atmosphere remains truly natural. It is ideal for Eco-Adventure tourists who want to experience the feeling of exploring a deserted island and relaxing simply in nature.
