If you're looking for a truly unusual experience in Hawaii, the Pineapple Garden Maze at Dole Plantation is hard to top. It's the Guinness Book-certified world's largest garden maze, occupying two acres and made up entirely of local vegetation, 14,000 plants in all. Visitors navigate 2.5 miles of beautiful hibiscus-lined paths in an effort to find eight stations, each of which brings them closer to completion of this larger-than-life labyrinth. Elsewhere on the plantation, you can take a ride on the Pineapple Express, a 20-minute train tour with narrators who explain the history of the pineapple in Hawaii, as well as the story of James Drummond Dole and his world famous agricultural empire. The Plantation Garden Tour, meanwhile, is a self-guided tour that appeals to all the senses, winding through eight different lush gardens replete with everything from coffee and exotic fruit to cacao pods, which are used to make Waialua's signature single-estate chocolate. Not surprisingly, Waialua Chocolate is available in the gift shop, along with every pineapple-themed novelty you can think of. It's a tasty way to learn about one of Hawaii's most important industries. Starwood has hotels throughout Oahu, including the Sheraton Waikiki.
