The Kalalau Trail begins at Ke'e Beach at the end of the road in Haena State Park and clings to the cliffs of the Na Pali coast. Day hikers can walk the first two miles to Hanakapiai Beach, a steep, muddy and breathtaking route with ocean views, stream crossings and tropical forest. A spur beyond the beach climbs two more miles to Hanakapiai Falls. Beyond mile two, the trail requires a camping permit and leads 11 miles to remote Kalalau Valley. Haena State Park uses a reservation system for out-of-state visitors, and the slots are limited, so planning is part of the hike.
This is the walk that defines hiking on Kauai. The trail rises from Ke'e Beach through lowland forest, climbs a steep ridge and then switchbacks along the coastline with views back toward Ke'e and forward to the pleats of the Na Pali cliffs. After roughly two miles, it descends to Hanakapiai Beach, a pretty crescent of sand backed by a valley.
Do not swim here
The beach has a long history of fatal rip currents and sneaker waves, and the signs warn of it. Most hikers rest, snack and turn back; the extra four-mile round trip to Hanakapiai Falls adds mud, stream crossings and a rewarding waterfall pool for those with the energy.
The practicalities are the story. Haena State Park limits the number of vehicles and visitors, and non-residents need advance reservations for entry and parking, released a set number of days ahead and snapped up quickly. A shuttle from the nearby Waipa area is an alternative that includes entry, and Hawaii residents have different rules. Check current requirements before you plan a day around it. Start early, because afternoon rain makes the mud worse and the stream crossings more dangerous, and tell someone your plans.
Wear shoes with real traction, carry more water than seems necessary and bring a rain layer. Do not hike when streams are running high, because flash floods happen quickly in these valleys. Camping beyond mile two requires a separate state permit and is a serious backcountry commitment. If you cannot get a reservation or the weather turns, you can still see the coast from the water on a boat tour or from the air on a helicopter or airplane flight, both of which reveal the same cliffs without the mud.
