After stepping off a flight to San Juan most travellers are left bewildered by the abundance of activities the capital of Puerto Rico has to offer. During the day outdoor enthusiasts can hike the rain forest and surf the waves, while at the night the city is transformed into one of the nightlife capitals of the Caribbean.

As a side trip, travellers booking flights to San Juan should plan to spend a few extra days exploring the coastal town of Guánica and the Caribbean National Forest, El Yunque, then on the way back to San Juan stop for a picnic or a quick dip in the country’s best-known beach, Luquillo.

For sightseeing, Old San Juan, the original city founded in 1521, has a wealth of well-cared-for 16th and 17th-century architecture, built by the Spanish colonists. Still partially surrounded by the wall built in 1633 and paved with the stones used as ballast on Spanish ships, the old city features tree-shaded squares, monuments, open-air cafes, and shops, as well as private homes with their wrought-iron railings on balconies filled with pots of tropical plants.

Getting around San Juan

What is good to know if travelling to San Juan?

  • One venue for Puerto Rico’s Latino chic is surprising — the Museo de Arte. Some Puerto Ricans come to the art museum at least once a week, and not just for its fine collection of Puerto Rican art. They also come for productions in the 400-seat theatre. And trendy locals can be seen strolling the museum’s lovely five-acre garden. 
  • San Juan has done a great job of adapting old buildings to new uses. La Princesa, for centuries one of the most feared prisons in the Caribbean, now houses the Puerto Rico Tourism Company. It features an exhibit of art by Puerto Ricans, which is free to the public.
  • Another example of reuse is the 19th-century insane asylum, the Antiguo Manicomio Insular, which is now the home of the Puerto Rican Academy of Fine Arts, with its lovely courtyard fountains surrounded by elegant iron fences.
