About this site
Manuka Bay lies along the southwest coast of the Big Island of Hawaii, in the Ka'u district between South Point and Honaunau. This stretch of coastline is remote and rugged, backed by lava fields and dry forest, with limited road access compared to the more developed Kona coast to the north. It is rated a beginner dive site.
