Old San Juan is the oldest settlement within Puerto Rico and the historic colonial district of the city of San Juan. Our first trip to Puerto Rico together was on a spring break trip in 2011. Old San Juan is filled with tons of bars, restaurants, and shops.
The Casa de Barcardi offers tours and mixology classes. We took a class on a trip and had a blast.

Fun place to visit and hang out. Lots of restaurants.
