San Juan Things to Do: 269 reviews and 649 photos


While walking around the old streets and neighborhoods of San Juan, you'll undoubtedly notice the blue cobblestone streets in many places. These blue or bluish-gray cobblestones are known as "aquinos" and actually were brought to Puerto Rico as ballast for ships sailing from Spain. It almost appears as if they were glazed but I could not discover what they derive their blue color from --- whether a particular stone or what. In any case, they certainly are unique and add another hue to the already very colorful streets of Old San Juan !

Directions: All around Old San Juan!
