Pololū (Hawaiian spelling: Pololū, stressed on the final 'ū') is the Northernmost of a series of erosional valleys forming the east coast of Kohala Mountain on the Island of Hawaiʻi. The word Pololū means long spear in the Hawaiian language.
Pololū Valley is accessed from the North, from a lookout forming the terminus of Akoni Pule Highway.
While Wikipedia describes the hike down to the beach as "A relatively short hike on a graded trail leads to the bottom of the valley", the trail is not easy and hikers stop frequently to rest on a rock or take a photograph through the tree cover.
The trail continues beyond the valley, climbing over a ridge to neighboring Honokane Nui Valley.
