Famed for its epic swells and chilled out surf culture, Oahu is all that, and much more. History-buffs can wander the sobering WWII site of Pearl Harbour and explore the colonial charm of Honolulu, gourmands are spoilt with fresh seafood and local produce, while the white sands, framed by swaying palms and concertinaed mountains, are the perfect spot to unwind with a fruity cocktail.
