Mu Ko Surin National Park

Mu Ko Surin National Park is a marine and island protected area in the Andaman Sea off Thailand’s west coast, administered from Phang Nga Province. The park comprises a small group of islands surrounded by coral reefs and clear waters.

The park is primarily visited for snorkeling, reef diving and short island hikes; the two largest islands, Ko Surin Nuea and Ko Surin Tai, host the majority of trails, beach landing sites and ranger facilities. Coral gardens and shallow reef slopes are the main attractions for day-trippers and liveaboard visitors.

The islands and their surrounding reefs are managed for marine conservation and tourism. Local sea nomad communities historically used the area, and park management balances visitor access with reef protection.

Mu Ko Surin sits offshore in the northern Andaman Sea, west of Phang Nga Province; boat access is required from the mainland and seasonal weather patterns strongly influence visiting windows.

• Seasonal access: The park's visiting season is seasonal and weather-dependent; boat trips and liveaboard services generally operate in the calmer months when visibility is best for snorkeling and diving.
• Cultural and marine highlights: Traditional sea nomad (Moken) presence historically links the islands to local maritime cultures, and sightings of reef species are best near shallow fringing reefs around the main isles.
