Girona and Costa brava have become popular biking destinations. You can explore the region on a bike following well-defined routes.
Girona is not just the gateway to Costa Brava but a popular tourist destination in its own right. Allocate at least a day in Girona.
Best time to visit
Again, the best time to visit Costa Brava depends on your interest. If you are looking for sun, sand, and water, then winter is certainly not a good time to visit. But the winter has its own charm if you are mainly interested in seeing the small towns and experiencing their culture.
There is no one tourist card that works for Girona & Costa Brava region, as it is made up of so many individual towns. For your Girona city visit you should consider picking up an M5 card that gives you highly discounted entry to 5 museums of Girona.
