San Juan, Puerto Rico's capital and largest city, sits on the island's magnificent Atlantic coast. The city's charming historic Old Town features lovely cobblestone streets, countless colourful Spanish colonial buildings, and an impressive array of 16th-century landmarks, including La Fortaleza, a massive palace and fortress with sweeping ocean views. Old Juan is compact enough to negotiate on foot, but free trolleys can take visitors from one site to the next. Beyond the old town, this modern metropolis offers all the amenities and entertainment of a modern city with the added appeal of tropical beaches, a lovely seaside promenade, luxurious beachfront hotels, world-class dining, and vibrant nightlife. This perfect mix of old and new makes San Juan such a unique and unforgettable holiday destination.
