Hat Jao Mai National Park

Hat Jao Mai National Park (also spelled Hat Chao Mai) is a coastal and marine national park in southern Thailand that includes mainland shorelines and offshore islands. The park protects beaches, limestone cliffs, sea caves and nearshore marine habitat.

Beaches, island-hopping, snorkeling and visits to sea caves and coastal viewpoints are primary attractions. Several offshore islands within the park are visited by day-trippers for snorkeling and beach access.

The area was designated and is managed by Thailand’s national park authorities to conserve coastal, island and marine ecosystems. Management covers both terrestrial and marine zones.

The park lies on the Andaman Sea side of southern Thailand within Trang Province, with access from nearby coastal towns and piers for boats to the offshore islands.

• Sea caves: Has coastal islands and sea caves; the well-known sea cave known as the “Emerald Cave” (Tham Morakot) on one offshore island is accessible by boat and is tidal, so entry is timed with sea conditions.

• If you plan island or coastal visits from the park, book boat transfers with park-approved operators or through the park office - services can be limited and weather dependent.
• Visit early in the day to take advantage of calmer sea conditions and clearer water for snorkeling around nearby islets before winds and boat traffic increase.
• Check with the park office on current access rules and any temporary closures for protected nesting or recovery areas to avoid inadvertently visiting restricted sites.
