Kaunaʻoa Beach (Mauna Kea Beach)

The beach is publicly accessible by Hawaiʻi law but the parking is the chokepoint — about thirty public-access stalls released first-come, fill before 8 AM. If you don't get one, walk in from somewhere else, do not argue with the valet. The honu — green sea turtles — that haul out on the sand are state and federally protected; stay ten feet back, fifteen if a turtle is nesting. Do not touch them. Do not flash photo them. The reef on the south end of the bay is the snorkel area; do not stand on coral, do not feed fish.
