    Description

    A paved 0.6 mile walk provides a scenic viewpoint of Kuka‘emoku (a.k.a. the ʻIao Needle), an erosional feature which abruptly rises 1200 feet from the valley floor.  Learn about the plants brought by the Hawaiians who settled in ʻIao Valley by taking a short walk through a botanical garden.

    This valley is rich in cultural and spiritual values and is the site of the battle of Kepaniwai where the forces of Kamehameha I conquered the Maui army in 1790.

     

    Publicity

    In 2016 Iao Valley State Monument ranked 24th in THRILLIST’s list of best 25 State Parks to visit in the nation.

    “To call this West Maui Mountains park “lush” is an understatement of epic proportions. Its dense rainforest canopy makes this popular park one of America’s more unique, dominated by the Iao Needle — a 1,200ft vegetation-covered lava remnant that rises from the valley floor to a higher height than the Eiffel Tower… “ THRILLIST
