Step on this multi-colored island ringed with miles of bougainvillea and poinsettia and you'll understand immediately why the royals of Hawaii chose it as their summer residence. The deep, rich soil is the breeding ground for two of the world's most unique treasures: macadamia nuts and Kona coffee, and there's plenty of both in the quaint shops, which also offer exquisite coral jewelry and hand-sewn muumuus. At the opposite end of quaint: Hulihee Palace, grand and majestic with a superb collection of royal antiques.
