Kalalau Beach is a beach on the Nā Pali Coast at the base of the Kalalau Valley in north-west Kauaʻi in Hawaiʻi. It is the final destination of the Kalalau Trail, one of the most difficult trails on the Hawaiian Islands. The beach is approximately 1 mile long, with trails snaking through the rest of the valley where people in hiding are rumored to live. There is a camp site on the beach, with a waterfall providing fresh water and composting toilets available. Camping requires a permit.
