What is "wailau"

Wailau is an isolated valley on the North Shore of the island of Molokai, Hawaii, United States. It can be reached only by boat (and only in the summer) or formerly by a hiking trail from the south coast of the island which is now overgrown and virtually impassable.

The valley was an ancient ahupuaa, and well populated until the 19th century, and contained many taro plantations. The valley is now unpopulated, although Molokai residents occasionally camp by the beach at the mouth of the valley in the summer.

In the Hawaiian language wai lau literally means "many waters".
