Back in the 1500s, Puerto Rico was one of the first Caribbean islands to be settled, and its capital, today's San Juan, became a vital hub of Spain’s New World colonies. The historic part of the city, known as Old San Juan, is now a UNESCO World Heritage Site; it's also a National Historic Site within the U.S. National Park Service.
Strolling the narrow cobblestoned streets of Old San Juan, you'll discover a historic treasure surrounded by massive city walls. You can climb the ramparts of imposing fortresses like El Morro, at the entrance to the bay, and visit the Cathedral of San Juan Bautista, one of the oldest churches in the Americas and the final resting place of the city’s founder, Ponce de León.
Modern San Juan extends well beyond the historic district and offers diversions of its own. Condado, a lively beachfront neighborhood, has high-rise resorts and trendy waterfront bars. Visitors may sample one of Puerto Rico’s best-known products at Casa Bacardí, the rum distillery across the bay. And stunning natural wonders await just outside the city, including the rain forest and waterfalls of El Yunque National Forest and the otherworldly lights of Fajardo’s bioluminescent bay.
