Ai'opio Beach, Big Island

Ai'opio Beach on the Big Island of Hawaii is part of Kaloko-Honokohau National Historical Park, a rich archaeological site just north of Honokohau Harbor. Here you can find artifacts showing how Hawaiians lived in the past, before Western contact and the changes that followed.

Surrounding the beach is the Ai'opio Fish Trap, a traditional fish trap designed for catching fish. Built by ancient island villagers, it traps fish that come in at high tide and remain inside at low tide, making for an easier catch. All that remains today is the dark lava structure around the trap, but it continues to fascinate local residents and visitors alike.

The beach is usually calm enough for swimming, even for small children who can play in the shallow tide pools. Offshore reefs are scattered throughout the area, which helps buffer incoming waves and currents.

Occasionally, turtles will swim up to shore and feed on the limu (seaweed). If you see one, stay at a respectful distance. Sea turtles are protected by law, and it is not allowed to touch, chase or disturb them.
