Start in San Juan
January is an excellent time for a Puerto Rico city break, especially if you want winter sunshine with plenty to see and do. San Juan combines a relaxed Caribbean feel with the energy of a historic capital, so you can spend the morning exploring old streets and the afternoon beside the sea.
Old San Juan is the natural starting point. Its brightly painted buildings, balconies and pretty squares make wandering a pleasure, while the area’s restaurants and bars keep it lively into the evening. Allow time to explore the impressive city walls and Castillo San Felipe del Morro, where the views across the Atlantic are as memorable as the history.
