Beautiful walking trails wind through this highly regarded 200-acre arboretum managed by the University of Hawaiʻi. It was originally founded in 1918 by a group of sugar planters growing native and exotic flora species to restore Honolulu’s watershed and test their economic benefit. This is not your typical overly manicured tropical flower garden, but a mature and largely wooded arboretum, where related species cluster in a seminatural state. For a guided tour, call at least 24 hours in advance.
