With stunningly gorgeous scenery, Halawa Valley enjoys end-of-the-road isolation, which residents guard jealously with gates and 'no trespassing' signs. It was an important settlement in precontact Molokaʻi, with a population of more than 1000 and a complex irrigation system watering more than 700 taro patches. Little remains of its three heiau sites, two of which are thought to have been luakini, but you'll probably still feel the charge down here.
As late as the mid-19th century, the fertile valley still had a population of about 500 and produced most of Molokaʻi's taro, as well as many of its melons, gourds and fruits. However, taro production came to an abrupt end in 1946, when a massive tsunami swept up the Halawa Valley, wiping out the farms and much of the community. A second tsunami washed the valley clean in 1957. Only a few families now remain.
