One of the highlights on my previous trip to Kauai is taking 2 miles hike in this Kalalau trail. This is the America's 10 most dangerous hikes. The Hike: Pictures of the dramatic and lush Na Pali Coast stir hikers' wanderlust, but the Kalalau Trail hugging this dramatic coastline also triggers something far less romantic: terror. "People have a hard time with some of the dropoffs," says Kathy Valier, a Kauai resident who's written guidebooks on hiking the island. "The trail bed is narrow and crumbly, and I've talked with many people who have either fallen off the trail or seen it happen." The footing is twice as treacherous after the island's abundant rainfall turns the track into a greasy slip 'n slide–not amusing when you're edging along a 300-foot cliff that spills straight into a rocky surf. But despite such dangers, tons of locals and visitors continue to make the 11-mile (one way) pilgrimage to Kalalau, one of the world's most paradisical beaches.
