San Juan Bay sits at the heart of the city of San Juan, with innumerable sites, neighborhoods and attractions ringing its shores. The most iconic spots on the bay are the pair of fortresses that face each other at the bay’s mouth. On the eastern side sits El Morro, flanked by the 500-year-old cobblestone streets of Old San Juan. Across the way, the Islas de Cabras National Park boasts the San Juan de la Cruz Fort. Both are UNESCO World Heritage Sites, but visitors can only walk around the outside walls of the San Juan de la Cruz Fort, as the inside in closed to the public. Just south of Isla de Cabras, you’ll find another icon of Puerto Rico overlooking the bay—the Bacardi Rum Visitor Center, where you can take a tour and enjoy a rum tasting.
For easy access to different side of the bay, or simply to take a trip on the water, hop the ferry in the port of San Juan for the 8-minute ride across to Cataño. From there it’s easy to catch a quick cab to the Bacardi Visitor Center or Isla de Cabras.
