Ahupua'a 'O Kahana State Park

Lonely Planet review

Ahupua'a 'O Kahana State Park (formerly Kahana Valley State Park) is in an incredibly rainy and unspoiled valley. You can walk through the valley on either of two hiking trails. The orientation center provides a trail map, but it isn't always open to visitors; trails tend to be poorly maintained and conditions slippery.

The park's most important site is Huilua Fishpond, on Kahana Bay, a survivor of the traditional ponds used by the Hawaiians to cultivate fish. Early fishpond technology typically used fresh and saltwater sources and strategic placement to protect it from large swells. Management of the pond was a communal effort governed by local beliefs in the magical powers of stones and protective lizards.
