Nāpali Coast State Wilderness Park, on the northwest coast 5 mi. w. from Hānalei Landing, is accessible by the difficult and dangerous 11-mile Kalalau Trail. The park includes the coastal area from Hā‘ena to Miloli‘i Valley as well as the Nu‘alolo and Kalalau valley regions, all with small beaches at the base of lava cliffs. Archeological sites of Nu‘alolo Kai’s and Nāpali’s early settlers are along the park’s rugged hiking trails; Nu‘alolo Kai is accessible only by boat. It is a 2-mile hike to Hanakāpī‘ai Valley and Beach.
Note: The Kalalau Trail is often muddy and slippery, and hikers should be aware of tree roots, rocks and stream crossings. Flash flooding is possible on the trail. Due to unpredictable ocean currents, swimming and wading along Nāpali Coast beaches are not recommended September through May. Camping permits are required beyond Hanakoa Valley.
Recreational activities are permitted. Camping is permitted. Picnicking is permitted.
