Kauaʻi packs an extraordinary range of landscapes into a small island: the sheer green cliffs of the Nā Pali Coast, the red-rock canyon at Waimea, the swampy plateau of Alaka'i, and a dozen beautiful beaches scattered around the shore. The activities here lean toward the outdoors — hiking, kayaking, snorkeling, and helicopter tours — and the island rewards those who leave the resorts behind.
