Mu Ko Surin National Park

Mu Ko Surin National Park is an archipelago and marine protected area in the Andaman Sea off western Thailand, noted for its coral reefs and marine biodiversity. The park includes several islands and surrounding reef systems that are managed for conservation and tourism.

Clear-water snorkeling and scuba diving on coral reefs are the primary attractions, with shallow reef slopes, coral gardens and frequent sightings of reef fish and larger marine life. Boat trips from the mainland typically run day trips or short liveaboard excursions to the islands; most visitor activity concentrates around the two largest islands and their reef fronts.

The islands and reefs were established as a protected area to conserve marine habitats and traditional use by local seafaring communities. Over time the area has been managed to limit fishing and regulate visitor access to protect coral and sea life while supporting tourism operations.

Geographically the park sits in the Andaman Sea off Thailand’s west coast, northwest of the mainland town of Kuraburi. The islands are several dozen kilometers offshore and are reached by boat from the mainland piers that serve southern Phang Nga and Ranong coasts.

• Best time to visit: Marine park waters are best for diving and snorkeling in the dry season, roughly November to April, when visibility and sea conditions are optimal.
• Local community: Traditional Moken communities have historically used the islands and visitors may sometimes learn about their maritime culture during local tours.
