Hike the Legendary Na Pali Coast, Kauai
Considered the state’s best backpacking route, the 22-mile round-trip Kalalau Trail cuts through the famed Na Pali Coast, an unspoiled wonderland where fluted cliffs and lush valleys crash abruptly into the blue Pacific. Originally built in the mid-1800s, the trail has narrow switchbacks, sheer drop-offs, and alarming, cliff-grabbing turns. Needless to say, only the brave and experienced need apply. After traversing five valleys, the path ends—as if the bounty for your trouble—at the golden sands of Kalalau Beach. Here, pitch a tent under the jungle canopy, then shower under the valley’s legendary beachside waterfall. Isolated and inspired, don’t be surprised if bidding "aloha" to the modern world comes to mind. Though state permits allow only five nights total (including time spent at Hanakoa, a campsite six miles from the trailhead) that doesn’t stop some wanderlust souls, including those who prefer the fashion sense of Adam and Eve, from making it their mission to avoid regular sweeps by officials.
