Kalalau Valley, one of the most beautiful valleys of the Na Pali Coast, is accessible only via an 11-mile hiking trail that begins in Haena State Park on the North Shore and continues along the Na Pali Coast. The Kalalau Trail is the only way to access Kalalau Beach, as boat landings aren't permitted. The Valley can also be viewed from Kalalau Lookout, located in Kokee State Park, or from a helicopter tour, most of which fly past the Na Pali Coast.
