If you're travelling with a vehicle in Bonifacio, note that there's almost no parking within the citadel. There are some large car parks at the southern end of the hilltop, but they tend to fill up in summer, and slow traffic means you can lose a lot of time driving up there only to find there's no room anyway. In high season, anyone driving into Bonifacio is recommended to park down by the marina as soon as possible. Note that if you're here for a boat-trip, SPMB offer customers free all-day parking.
