San Juan, Puerto Rico

Beyond its timeworn 15ft-thick walls, San Juan is far more than a collection of well-polished colonial-era artefacts – it’s also a mosaic of ever-evolving neighbourhoods such as Santurce, which has a raw vitality fueled by street art, superb restaurants and a bar scene that takes over the streets at night.

And then there are the beaches. Silky ribbons of sand line San Juan’s northern edge from swanky Condado to resort-filled Isla Verde. You can land at the airport and be splashing in the azure waters an hour later.
