The best is to go on the north side in 15 to 20 meters with access to the large hong that gives the island its name. It is possible to enter the hong by dinghy over the shallow bar on tides over 2 meters and explore the lagoon, which at 200 meters across is one of the largest in the area. If there is not enough water to enter and leave the hong by dinghy you will need strong shoes, as the rocks are sharp with many sea urchins.
Groundswell can make this anchorage/mooring uncomfortable.
On the southeast side of the island is a pretty bay with reasonably clear water suitable as a day stop in calm conditions only. There is a ranger station ashore and if you visit the beach you will be asked to pay a National Park entry fee.
Lots of mooring buoys have been laid which can be used for lunchtime stops but beware that the ones near to the beach are very close to the reef and are not suitable for yachts.
Beware of the fringing reef which shelves suddenly as you approach the beach and can be exposed at low water.
