Start in San Juan
Puerto Rico is a superb choice for a solo holiday in September, especially if you like having plenty of freedom without feeling isolated. Begin in San Juan, where historic streets, lively cafés and welcoming local restaurants make it easy to settle into the island’s rhythm. You can spend the morning exploring at your own pace, then join a guided walk or food tour when you fancy some company.
Old San Juan is the perfect introduction. Wander past brightly painted buildings to the impressive forts of Castillo San Felipe del Morro and Castillo San Cristóbal, stopping for coffee or a chilled drink along the way. In the evening, the atmospheric streets fill with music and conversation, giving solo visitors plenty of relaxed opportunities to meet people.
