Kekaha Kai State Park (Kona Coast State Park)

Some of the most pristine white sand beaches on the entire island hidden behind rugged lava fields. Three distinct beaches — drive to Kua Bay (Maniniʻōwali) for the easiest family access with lifeguards, showers, and restrooms. Makalawena Beach requires a 20–30 minute hike over rough lava and is worth every step — crystal clear turquoise water and almost no crowds. No shade anywhere so bring hats, sunscreen, and more water than you think you need. Closed Wednesdays. Note: the dirt road to Mahai'ula may damage rental cars — check your rental agreement first.
