San Juan is the capital of Puerto Rico, a US territory, so travelers from the mainland US do not go through international immigration. The walled Old San Juan district, with its forts at El Morro and San Cristobal, is the main historic draw, while Condado and Isla Verde hold most of the beachfront hotels. Luis Munoz Marin International Airport sits in Carolina, a short drive east of the city.
