Halekiʻi-Pihana Heiau State Monument is a 10 acre park containing two important heiau (religious sites) near the mouth of the ʻIao Stream in Wailuku. Halekiʻi and Pihana were associated with important Hawaiian chiefs. Originally they were places of worship, only to be changed to war temples.
The site is open to pedestrians only (the entry road doesn’t permit vehicles).
The heiau complex was added to the National Register of Historic Places in 1985.
