Founded in 1521 by Ponce de Le?n, the capital of Puerto Rico, San Juan, is the oldest city in US territory. Home to 1.6 million (more than a third of the island's citizens), it is also the heart of Puerto Rican tourism. What draws travellers here year-round are miles of smooth, clean beaches, a wide range of accommodation, fabulous restaurants and, of course, Old San Juan, whose beautifully restored historic sights surrounded by crashing turquoise surf are reason enough to make a trip to Puerto Rico. __
