Kauai is Hawaii's best-kept secret; yes, Maui is gorgeous and Honolulu has a lot going on, but the "Garden Isle" is simply surreal. Hawaii's oldest island, Kauai is smothered in emerald valleys, tropical rainforests, dramatic cliffs, and some of the best hiking you'll ever encounter. Actually, even if you've never been, you've seen the landscape before if you've seen Jurassic Park. Check out the Ko'a Kea Hotel & Resort at Poipu Beach, where you can wake up to views of the Pacific Ocean crashing into the shore. Room service, anyone?
