Tucked in the tropical rain forest of Soufrière on St. Lucia is the 250-year-old working plantation of Fond Doux. The 15 French Colonial fretwork cottages—some of which were moved from other island areas—were restored, then outfitted with four-posters and rocking chairs. A vacationer here can subsist on the verdant land’s spoils, including fresh-plucked bananas, breadfruit, mango, guava, and . . . cocoa. Cocoa harvesting and rolling is done right on the plantation.
