Ahupuaʻa ʻO Kahana State Park
Ahupuaʻa ʻO Kahana State Park is Hawaii’s only publicly-owned ahupuaʻa – a traditional Hawaiian land division stretching from the misty Ko’olau Mountains to the turquoise waters of Kahana Bay. This “living park” on O’ahu’s windward coast offers a rare blend of hiking through tropical rainforest, beachfront camping, and authentic Hawaiian cultural experiences – all while 31 Hawaiian families continue to live and share their heritage within the park.
Unlike any other state park in America, Kahana represents a complete ecosystem and cultural landscape where visitors don’t just observe Hawaiian traditions – they experience a living community that has called this valley home for generations.

⚠️ Trail Conditions
Both trails can be muddy and slippery due to frequent rainfall on the windward coast. The Nakoa Trail crosses Kahana Stream twice – do not attempt during heavy rain or high water due to flash flood risk. Wear sturdy hiking shoes with good traction.

Huilua Fishpond (National Historic Landmark)
The Huilua Fishpond is one of O’ahu’s best-preserved loko iʻa – a traditional Hawaiian aquaculture system dating back over 600 years. Designated a National Historic Landmark, this ancient fishpond demonstrates the sophisticated resource management that sustained Hawaiian communities for centuries.
How it works: Stone walls create a semi-enclosed pond where juvenile fish enter through sluice gates, grow to maturity, and are harvested – an ingenious sustainable food system.
