Koh Khai

The famous stone arch

Koh Khai is a speck of an island between Koh Tarutao and Koh Lipe, and one of the most recognisable sights in the Andaman Sea: a natural stone arch of weathered rock standing in clear, shallow water beside a small beach of white sand.

Its name means “egg island” — sea turtles have traditionally come ashore here to nest. The arch features in countless photos; a popular local saying holds that couples who pass beneath it together will stay together.

Top things to do at Koh Khai

Photograph the arch

The arch looks best from the water or from the beach at an angle. Mid-morning light makes the water glow.

Swim and snorkel

The water around the island is clear and shallow, with some coral. Stay off the rock and away from any marked turtle-nesting areas.

How to get to Koh Khai

  • From Pak Bara or Tarutao: Koh Khai is often combined with Koh Tarutao on day trips from the mainland, and some Pak Bara boats pass close by.
  • From Koh Lipe: reachable by chartered longtail or speedboat in good weather; it is further than the Adang–Rawi islands, so ask about sea conditions.

Insider tips

  • Landing time is usually short — the island is tiny and has no facilities.
  • Like the rest of the park, it may be closed or unreachable in the monsoon season.
