Known as the Garden Isle—it’s the greenest of all the islands—Kauai lies at the northern end of the Hawaiian chain. Shore excursions include film location tours, as well as tours to Waimea Canyon, known as the Grand Canyon of the Pacific. Ships dock in Nawiliwili Harbor on the island’s southeast coast, near the town of Lihue. A rental car is the best way to get around if you aren’t taking an organized tour.
Kauai attracts visitors throughout the year, but it's most crowded when US schools have vacation (notably in summer and the two weeks around Christmas and New Year’s). Rainfall is highest in winter and early spring, so visiting in Apr. or May or in autumn is best for good weather and fewer crowds.
