One look at Kauai and you'll understand exactly why it's called the Garden Isle. You might confuse the lush, green mountains and wide valleys giving way to waterfalls for Costa Rica, Belize, or even Tahiti. The highlight of the island, is the Nā Pali coast, emerald cliffs towering over the Pacific Ocean that are best explored by helicopter or boat. If it looks like a scene from Jurassic Park, well...that's because the hit Steven Spielberg film was partially filmed there.
