Best time

Why go

The reason to stop here is not the island itself but the sand around it. At low tide a sandbar, known locally as Talay Waek, comes out of the water and joins Koh Tup to Koh Mor and to Chicken Island, and you can walk between them.

What you will find

Small limestone islands close together, with the sandbar running between them. How much of it you see depends entirely on the tide on the day: on some days it is a wide path, on others a strip of wet sand, and at high tide it is under water.

Getting there

By boat only, as a stop on a four-island tour from Ao Nang or Railay. Both four-island tours we list include the Koh Tup stop or the sandbar walk to Koh Mor.

Before you go

The tide moves to a different time every day. If the sandbar matters to you, look at a tide table for the date before you book, and ask the operator whether their timing on the route allows for it.

Koh Tup is counted in the same national park as Koh Poda and Chicken Island: the park fee is usually paid in cash on the day, and the amount quoted for these islands varies between sources.

Common questions

Can I walk to Koh Tup?

Only from its neighbours, and only at low tide: the sandbar joins Koh Tup to Koh Mor and Chicken Island when the water is out. From the mainland you need a boat.

When is the Koh Tup sandbar visible?

At low tide, and the time of low tide changes every day. Check a tide table for your date rather than trusting a fixed hour.
