Koh Prao Nai belongs to the group of islands which are situated in the southeastern side of the island of Koh Chang and near the mouth of Salakphet Bay. Koh Prao Nai Island is surrounded in the four directions with significant places or islands which are relatively near. It is only a kilometer away from the island of Koh Mapring from its north side. On the western part, Wat Khao Rong Than is just around 1.2 kilometers away. From its southeast side, Koh Prao Nok Island is also 1.2 kilometers away. And Ao Krarang is distanced by 1.2 kilometers away from its east side. Koh Prao Nai Island can be reached by motorboats, speedboats, jetskis or kayak coming from any of the four directions.
Koh Prao Nai Island has no beautiful white sand beaches. Its coastlines are mostly covered with plants. Looking from afar, the island is a mound covered with natural green vegetation atop its land mass. Its natural setting makes trekking or mountain climbing a good thing to consider when you want to discover the natural jewels that are hidden in the rainforest of Koh Prao Nai. This can be possibly done with permission from authority since the island is part of Mu Koh Chang National Park and Koh Chang Marine National Park which protect and preserve the entire area.
The eastern side of the Koh Prao Nai is considered interesting. On its front shoreline you can see few fisherfolks live in stilt houses. Some of these stilt structures are used in catching fish or a sort of fish trap mechanism. The tip protruding potion of the island serves as shelter to a small bay. The absence of a beachfront can be complimented by drawing closer to the island coastal area and from there you can drop the anchor and above the boat you can take your food and drinks facing those stilt houses and enjoy the seaviews. Though its seabed does not look clear but the water surrounding the island is pristine and clean. You can still enjoy the fun in ways you find worth taking.
