Kauai
A coastline so sheer that the only way to see most of it is by boat or helicopter, a canyon nicknamed the Grand Canyon of the Pacific, and a rainforest interior wet enough to be one of the soggiest spots on earth.
The best time to visit Kauai is Apr–Oct, when typical daytime highs reach about 27°C (80°F). Local time there is 20:03 (UTC-10).
