Museo Castillo Serrallés
Castillo (castle) may be an overly generous descriptor for the former home of the Serrallés rum dynasty, but the estate is an impressive spread, especially if you buy a combination ticket that allows you to explore the grounds. Tour the house with a guide to learn more about the Serrallés family before visiting the Japanese garden and ascending to the observatory level of the Cruceta del Vigía, a cross-shaped structure. You can see all the way to the Caribbean through the observatory’s floor-to-ceiling windows.
