Kalalau Trail, Kauai, HI

4 of 12

The cliffside trail along Kauai’s northern shore is on the life list of most long-distance hikers and rewards them with views of steep jungle valleys and treks along the faces of sheer sea cliffs toward untouched Pacific beaches. The walk is best enjoyed slowly, especially in winter months when humpback whales breach in the surf below. Round-trip, it's a 22-mile outing; sightseeing helicopters overhead can make the return trip in little under an hour.

Challenge Level: Medium.

Essential Gear: Thar she blows! Oh, you missed it? These digital binoculars have instant replay. (Bushnell; $399.)
