Warm evenings year-round, swaying palm trees and a spot of ukulele music...it must be Hawaii. Set up camp on any west-facing beach on one of these stunning islands and a sunset to remember is likely to be your reward. On Oahu, try lounging on the sand at Kaanapali, sipping a cocktail at Duke's Bar in Waikiki or mingling with the surfers at Sunset Beach (no relation to the scary 1990s soap). It didn't get that name for nothing...
