Viejo San Juan is home to a variety of top attractions, including El Morro, Castillo San Cristóbal and Calle del Cristo. It's here you'll find Calle de la Fortaleza, which once held the city's famous umbrella installation but is now adorned with a massive Puerto Rican flag. While most people do take advantage of seeing the historic and iconic sights, many also visit Old San Juan just to experience the area. Many of the best tours in Puerto Rico include strolls through this area. Numerous travelers encourage others to walk the cobblestone streets to view the historic, colorful architecture and experience the vibrant culture. No need to leave for lunch, this section of town is bursting with street vendors and restaurants ready to satiate your appetite. At night, the city comes alive and is filled with a bustling nightlife known for its drinks and dancing.

For optimal strolling, past visitors recommended seeing the area early in the morning before tourists wake up and vacationers disembark from their cruise ships (the cruise port is at the base of Old San Juan). Should your feet get tired, you can hop on the free trolley that operates throughout this part of town; however, know that it can run infrequently. You can visit Viejo San Juan 24 hours a day, but know that individual bars, shops and restaurants operate their own hours.
