Hiking and Backpacking

Well-traveled hikers and backpackers will tell you that some of the best hiking in the world can be found on Kauai. The Kalalau Trail along the island's Na Pali coast is considered world-class. Likewise, adventures down into Waimea Canyon or up in the Koke'e area are often proclaimed as outstanding. You might be forewarned that some trails, such as the Kalalau, have a daily quota and require reservations far in advance. For detailed trail descriptions, take a look at the following volumes:

• Robert Stone, Day Hikes on Kauai (Day Hike Books, 2001).

• Robert Smith, Hiking Kauai: The Garden Isle (Hawaiian Outdoor Adventure, 2002).
