19 miles from Yacht haven
Anchorage can be found in a small southwest facing bay with a rocky, off-lying islet on the north side. The bay is deep until close in and vessels can anchor in about 8-12 metres on a muddy bottom with some rock.
Several hundred metres to the west the water is generally shallow and the approach should be made close to the island. A great anchorage in the northeast season and reasonable in the southwest season.
There are two beaches and a large, attractive hong can be entered on foot at all but high tide from the west beach. Fringing coral prevents access to either beach at low tide. This island marks the limit of VHF radio communication with Phuket, before Koh Yao Noi masks it.

The rock just off the southern point of Koh Roi is a danger to deep draft vessels. Beware.
