Base yourself in San Juan, making minimal long-distance moves westward. Focus on historic sites, rainforest exploration, and one night of bioluminescent bay viewing—keeping the pace unhurried. Uber is affordable and convenient in the San Juan metropolitan area; rent a car only for the rainforest day or opt for a private car throughout.
After arrival and check-in: Enter via Puerta de San Juan → Stroll blue-brick streets and colorful balcony neighborhoods → Evening at Morro Fortress lawn to watch sunset kites → Dinner in Old San Juan. The Old Town core is walkable; wear comfortable shoes for cobblestones and watch your step on wet post-rain surfaces.
Visit Castillo San Cristóbal → Scenic overlook at La Puntilla Cemetery → Old San Juan market and souvenir shops → Afternoon Bacardi rum tasting tour → Evening salsa club. Most salsa clubs offer beginner lessons; no experience needed. Casual dress is fine.
Early departure to El Yunque National Forest (advance reservation required). Explore La Mina Falls trail, Yokahu Tower viewpoint, and a brief mangrove walk. Evening dinner in Fajardo followed by a bioluminescent bay night tour at Seven Seas Bay. Overnight in Fajardo or return to San Juan. For brighter Mosquito Bay, take a day trip to Vieques Island—adding an extra day makes it more relaxed.
Morning at Condado Beach or Pinones Beach → Last-minute shopping in Old San Juan (coffee, rum, crafts) → Afternoon airport car return and departure. Allow 3 hours for international flights; weekend queues at the airport can be long.
