The Kalalau Valley is located on the northwest side of the island of Kauai in the state of Hawaii . The valley is located in the Nā Pali Coast State Park and houses the beautiful Kalalau Beach . The Na Pali Coast is very 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 renowned for its natural beauty; it is surrounded by lush cliffs more than 2000 feet high. The valley 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 flaura 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 any one from residing there.
