See Cuba as Columbus first saw her -- by sea -- on a cultural cruise along the island's Caribbean coast, with its pristine beaches and rugged mountains. From UNESCO-listed Cienfuegos, "the Pearl of the South," cruise east to Trinidad, another World Heritage Site, with its well-preserved colonial architecture. Call at less-visited Isla de la Juventud and idyllic María La Gorda, a UNESCO Biosphere Reserve. Conclude with two days in Havana docked in the harbor alongside the atmospheric Old City. Optional postlude in Havana.
