Although you’ll need a car to get anywhere else on the island, you don’t need wheels in San Juan, especially Old San Juan, which is compact and traffic-choked (there’s also a free trolley that navigates the old city). Frequent bus service links the four-mile coastline where most of the city’s accommodations and sites are found, running between Old San Juan, Condado, Ocean Park and Isla Verde.
