Kalalau Trail, Kauai
The primary access route to the rugged Na Pali Coast, this 11-mile one-way footpath represents one of the most popular (yet rigorous) hikes in Hawaii. From Ke’e Beach, north of Hanalei, the trail traverses five valleys before ending at Kalalau Beach, an oasis of sheer cliffs, giant palm trees and greens that make Oz look brown. Along the way, you’ll pass breathtaking beaches, waterfalls, and naturist encampments. Unofficial boat transfers are available back to Hanalei, but be warned: To meet the boats, you’ve got to swim.
Time to budget: 3 days/2 nights
When to go: Year-round
