North Kona Beaches

Kahalūū is the Big Island's most popular snorkeling beach — a fringing reef just steps from shore with sea turtles, humuhumunukunukuapuaʻa, and hundreds of fish. Water quality is generally good but the high visitor volume and proximity to the road can affect conditions. Avoid after heavy rain. Best visibility in the morning before wind picks up.

Magic Sands Beach has white sand in summer and exposed rock in winter — hence the name. When the sand is present, it's one of the best swimming and bodysurfing beaches in Kona. Small, protected bay, minimal runoff. Moderate-low risk. Located just south of town, very accessible. Check if the sand is "in" before visiting.

The Old Kona Airport State Recreation Area offers a long stretch of beach along the decommissioned runway. Good snorkeling on the rocky sections, calm swimming in sandy areas. Water quality is generally good with open ocean flushing. Minimal development — a local favorite for picnics and leisurely snorkeling.

Honokohau is a secluded beach within Kaloko-Honōkōhau National Historical Park. Famous for Hawaiian monk seal and green turtle sightings on the sand. Water quality has a moderate risk due to nearby boat harbor runoff. The beach itself is pristine, but the harbor creates some water quality concerns. Worth visiting for wildlife, not just swimming.

Makalawena is one of the most beautiful and uncrowded beaches on the Big Island. The rough 1.5-mile lava road (high-clearance vehicle needed) or 30-minute walk across lava field keeps crowds away. Stunning white sand, crystal-clear water, excellent snorkeling at the rocky ends. Water quality is outstanding. Bring everything — no facilities.

Kua Bay (Maniniowali) is a picture-perfect white sand beach with bright turquoise water inside Kekaha Kai State Park. Paved road access makes it more popular than Makalawena, with a parking lot that fills early. Strong shore break in winter makes it more of a summer beach. Excellent water quality — one of the best on the Big Island.
