The Na Pali Coast is a beautiful, yet sometimes hazardous park. The cliffs at the park provide a rugged grandeur of narrow valleys ending at the sea. The views are spectacular. Waterfalls and streams are plentiful throughout the deep cuts of the valley cliffs. Camping is an extremely popular activity at this park, but permits are required. The park does not offer drinking water, so bring treatments with you. Several hiking trails are available for visitor use.
The Kalalau Trail is the most popular. It is a moderate to difficult trail with exceptional views of wet gulches to open ridge line. Permits are required.
Trailhead for Kalalau Trail at end of Kuhio Highway (Hwy. 56) in Ha'ena State Park; Kalalau and Miloli'i Valleys also accessible by kayak from May 15 through September 7. Nu'alolo Kai accessible for day use by commercial boat tours or by private boats.
