Museo Castillo Serrallés

On the same property as the mammoth El Vigía, Museo Castillo Serrallés was the home of Ponce’s rum dynasty, the Serrallés family. Guides lead bilingual walking tours through the lovely Moorish-style castle; when the somewhat exhausting hour-plus tour comes to an end, you can order snacks and drinks at the cafe. Relax on the terrace under the red-tiled roof and enjoy a view of the city below and the quiet burble of the garden’s fountains.
