Pentagon is a boat accessible salt water dive site, located in Waikoloa, HI. The maximum depth is 41-50ft/12-15m. The average visibility is 71-80ft/22-24m.

The Pentagon is just outside Anaehoomalu Bay in Waikoloa on the Big Island. It is a complex of lava caverns with 5 large openings (thus the name) that lead to interweaving tunnels and archways. Lots of swimthroughs and lava caverns.
