Hōnaunau-Nāpōʻopoʻo, Hawaii

Two Step, Hōnaunau Bay There is no sand at this Big Island favorite: you step off natural lava ledges into clear water just outside Puʻuhonua o Hōnaunau National Historical Park. Near shore it is about 6 to 10 feet deep, dropping to around 25 feet farther out, and turtles are almost always around. Watch the surge for a few minutes first and time your entry for when the water is up. Much of the coral on the right side died in the 2014 and 2015 bleaching, while the left side fared better, so head left. Spinner dolphins rest in the bay, and federal rules keep swimmers at least 50 yards away from them.
