Havana evokes images of colonial buildings, candy-colored “Yank Tanks,” and what locals call the perfect Cuban marriage: coffee, cigars, and rum. Explore Cuba’s enigmatic capital — a UNESCO World Heritage Site — when Holland America Line cruises to La Habana. Visit Hemingway’s former hangouts, watch a cabaret extravaganza, and engage in a community project at the Las Terrazas eco-village. In Cienfuegos, the “Pearl of the South,” you can tour a cigar factory and join a graphic arts workshop.
