The Kalalau Valley is located on the northwest side of the island of Kauaʻi in the state of Hawaiʻi. The valley is located in the Nā Pali Coast State Park and houses the Kalalau Beach. The Nā Pali Coast is rugged and is inaccessible to automobiles. The only legal ways to access the valley are by kayak or by hiking the Kalalau Trail.
The valley is surrounded by cliffs more than 2,000 feet high. This valley's bottom is broad and relatively flat, with an accessible region about 2 miles long and 0.5 miles wide. The abundant sun and rain provides an ideal environment for flora and fauna. Many native Hawaiians lived in the valley into the 20th century, farming taro from a vast complex of terraced fields. Today, its designation as a state park forbids anyone from residing there.
