The harbor is identified by the lighthouse on a point just south of the anchorage and by a few houses and warehouses that are easyly visible from the water.
Anchor in sand , in 30 to 40 feet of water.
Mahukona is an excellent dive for those who have a few dives under their belt. The entry is very easy and there is a hot water shower to alleviate the chills of an hour long dive (the shower pipe runs over the lava, and is heated by the Sun -- very nice!). Since this is still used as a small boat harbor, a dive flag is recommended, as always.
