If you're not up for the 11-mi haul to Kalalau Beach, then hike 2 mi along Napali Coast's Kalalau Trail to Hanakapiai Beach. It'll take about 1½ hours. Just don't get in the water. Ever. The water here is what locals like to call "confused." It has something to do with the radical change in water depth and sheer cliff walls creating wicked currents, rogue waves, backwash, undertow, cross waves, and rip currents. Instead, enjoy a picnic away from the ocean's edge. In the winter when the surf eats up the beach, this might mean perching on the lava-rock boulders backing the sand. To reach the beach, you'll have to boulder-hop across a stream. During heavy rains or even just after, the stream can flood, stranding hikers on the wrong side. This has resulted in helicopter rescues, so don't cross unless the boulders are visibly exposed. Amenities: toilets. Best For: solitude; sunset. www.hawaiistateparks.org.
