The streets are crowded with sightseers and shoppers but most startling is how clean the streets are. You're free to wander leisurely at will, both night and day, without barkers or time-share salespeople getting in the way. A two-hour walking tour guides visitors to the heart of this bustling city. There are plenty of shady parks and cool refreshment stops along the way. If the day is extremely hot, the complimentary trolley is a welcome sight.
Passengers can get on and off at any stop in the Old City.
San Juan was part of the Spanish empire for four centuries and its traditional architecture is strongly influenced by Spanish styles. Old San Juan is protected as a designated National Historic Zone, National Historic Site and World Heritage Site. The buildings and fortifications are among the best preserved of Spain's colonial cities. The oldest fortress still standing in the New World is the imposing El Morro Castle. The U.S. National Park Service provides guided tours.
