About San Juan

San Juan is Puerto Rico's capital and the gateway to the island — Old San Juan's colorful colonial streets, El Yunque rainforest, bioluminescent bays, and beaches. It's a US territory (no passport needed, use USD), so it's easy for Americans. The food is incredible (mofongo, lechón, piña coladas). Hurricane Maria (2017) recovery ongoing.

Highlights

  • Old San Juan (colorful colonial streets, El Morro fort)
  • Piña coladas at Barrachina (birthplace)
  • Day trips to El Yunque rainforest (45 min) or bioluminescent bay (Vieques, 2 hours)
  • Mofongo and lechón (roast pork) at local spots
