Kauai is called the "garden isle" for a reason. In the mountains of Koke'e, lush swamps ring with songs of rare birds, and the aroma of ginger blossoms sweetens the rain forests of Ha'ena. You can explore this Pacific paradise by land, sea, and air -- hiking along the Kalalau Trail, kayaking up the Hanalei River, or hovering in a helicopter high above 5,148-ft Wai'ale'ale, the wettest spot on earth.
