Avoid the crowds, just for you and your selected group. We created one of the most comprehensive and charming tours of the historical city Santo Domingo. Tour covers all major historical highlights with a local guide. Santo Domingo is the capital of the Dominican Republic and one of the Caribbean's oldest cities, known for hosting the first European settlement in America. Its walled, cobblestoned historic core, the Zona Colonial, has buildings that date to the 1500s.
