In ancient times, the Waimea Valley belonged to the kahuna (priestly class of Hawaiians). In 2006, The Trust for Public Land helped the Office of Hawaiian Affairs reacquire the 1,875 acre valley, one of the last intact ahupua'a (traditional mountain to sea land division) on the island of O'ahu with special funding from the US Army.
The valley contains a spectacular waterfall, the recently restored the Hale o Lono heiau (an agricultural temple), an extensive botanical garden that includes hundreds of rare and endangered plants, and hundreds of Hawaiian cultural sites.
