Société Générale

The local branch of Société Générale, one of France's largest banks, sits on Avenue Christophe Colomb and handles everything from currency exchange to account services. If you just need cash, there's an ATM on-site — handy since many smaller spots around Calvi still run on euros-only. It's a no-frills, get-in-get-out kind of stop when you need to sort your finances before heading further into Corsica.
