Old San Juan

The 500-year-old walled city, El Morro, and the dense seven-by-seven-block historic core most visitors land in first.

Old San Juan (Viejo San Juan) is the seven-by-seven-block walled city the Spanish founded in 1521, and it's still the densest walking-and-history zone in the Caribbean. The two National Park Service fortresses (El Morro to the west, San Cristóbal to the east) anchor the visit, the Catedral Metropolitana on Calle del Cristo holds Ponce de León's tomb, and the dining-and-bar corridor along Calle Fortaleza and Calle del Cristo carries the evening. Calle San Sebastián is the late-night bar strip year-round and the marquee of the January Fiestas. Old San Juan itself doesn't host JRCM-licensed dispensaries — historic-district preservation rules don't fit the signage — so adults 21+ on a temporary patient registration handle the supply run from Santurce or Condado (10–15 min Uber) and treat the historic district as a non-cannabis day with the consumption frame at the rental. The fortresses are federal jurisdiction; the cathedral and most of the streets are public space.
