Where: The northwest coast of the Hawaiian island of Kauai
Why: The sheer size of this 16-mile-stretch of volcanic cliffs is breathtaking to behold. There's an almost supernatural quality to the bare, rugged landscape—one of the reasons it's served as a backdrop for films like Jurassic Park and King Kong.
How: Inaccessible by car, the easiest way to take in the Na Pali Coast is by boat. We like Captain Andy's for sailing trips that range in length and include extras like snorkeling stops, dinner, and drinks. And, if you're visiting during the December to April whale season, you're also likely to experience the incredible sight of humpbacks breaching out of the water. Another way to see the coast is from the air with any of the region's helicopter tour operators. Outdoorsy-types with the right permits and know-how can also opt to experience the coast on foot with a hike along the 22-mile Kalalau Trail.
