At three square miles, Old San Juan is perfect for strolling. Walk the cobblestone-lined streets and soak up a neighborhood filled with history and colorful architecture.
Old San Juan is home to two old forts, including Castillo de San Felipe del Morro.
San Juan, Puerto Rico, was called La Ciudad Amurallada, the walled city. The walls reach 42 feet at their highest and can be as thick as 45 feet at the base.
The Paseo del Morro is a trail that runs from Old San Juan to the harbor.
El Paseo del Morro is staffed by many feral cats. A local group, Save a Gato, provides food in addition to trapping -- then vaccinating and neutering -- and releasing them back.
