The Kalalau Trail is a trail along Nā Pali Coast of the island of Kauai in the state of Hawaii. The strenuous trail runs approximately 11 miles (18 km) along the island's north shore from Keʻe Beach to the Kalalau Valley. Expert hikers can complete the roundtrip 22 mile trek as a day hike, but the average hiker requires a two-day minimum and will camp along the trail.
