Hualalai to Hapuna: each resort has its own beach cove, and every one is public.
The Hawaii Department of Health recommends staying out of the ocean for at least 72 hours after heavy rain. The Kohala Coast is Big Islandʻs driest area, receiving less than 10 inches of rain per year. This makes it one of the most consistently clean swimming areas in all of Hawaiʻi.
The Kohala Coast stretches along Big Islandʻs dry northwest shore, from Hualalai in the south to Hapuna in the north. Built on ancient lava flows, each resort complex has its own carved-out beach cove. The landscape is stark black lava with green oases at each resort. Less than 10 inches of rain falls here annually, giving the Kohala Coast some of the cleanest ocean water in Hawaiʻi.
