Sky High Flight Facts for Your Trip: Raleigh Durham to San Juan

The city attracts throngs of visitors with its sandy beaches, historic forts, a rich colonial architectural heritage, and a loud musical ambiance. San Juan is also home to several hotspots that offer fine dining and entertainment scenes.

Things to do in San Juan

San Juan Viejo

Home to almost 500 years of first-rate architectural and historical identity, San Juan Viejo is the older part of the city of San Juan. The area is known for its historic forts and more than 400 beautifully restored 16th- and 17th-century colonial buildings. One of the prominent highlights here is the Fuerte San Felipe del Morro, a fortress set on a raised land overlooking the sea.

El Morro is a 16th century fortress built on a point of land just above the Atlantic Ocean. It was completed over a period of 250 years as it was continuously subjected to many pirate raids and attacks from the sea pirates. The fort features a maze of ramps, outposts, barracks, dungeons, and tunnels that are all dotted with circular sentry boxes.

Castillo de San Cristobal

Castillo de San Cristobal is spread across more than 27 acres with 5 individual units linked by moat and tunnel. It is the largest fort ever erected by the Spanish in the Americas or the New World. The difference between El Morro and the Castillo is that the former was constructed to defend against attacks by sea while the latter was constructed to guard against a land-based attack.
