11 miles from Ao Nathon, Samui
Approaching from the east beware of the unmarked rocks just past Lamai Beach. Anchor between the islands in 5-6 metres on a muddy bottom, clear of the fringing reef on Koh Katen’s east coast. The approach from the west is clear and deep, following Koh Katen’s north coast.
With a small resort ashore, this is a pleasant and secluded overnight spot or an ideal day destination from the main island. There are trails through the mangroves leading to caves ashore.

On the southwest corner of Samui are five islands where the locals collect bird’s nests. The waters around the islands are deep, so this is not one of our recommended overnight anchorages although day anchorage can be found on the eastern side of Koh Mae Tap.
On the southwest side, shelter can be found from strong winds without dropping the pick. There is a cave that runs right through the island. Koh Bon is great spot for a swim to cool off.
Many small shacks cling to the steep cliff faces and bamboo scaffolding used by the nest collectors can be seen rising to the top of the sheer rocks.
