Hike the Fantasy Island. What’s known as one of the most beautiful coastal hikes in the entire world, the Nā Pali Coast on the island of Kauai (Hawaii) blends the majesty of steep mountains right alongside the tropical Pacific. This trail, which you’ve likely seen in movies and TV countless times, is no casual hike. The 11-mile hike will tax you with the heat and narrow trail, but when you reach the Kalalau Beach, you’ll marvel at the steep waterfalls and tropical jungle, and best of all, you can camp right there on the beach. Hey, no one said getting to paradise was going to be easy, but it’s well worth the hike.
