Such a cool free thing to do while in Calvi. The place is pretty impressive as you walk up to it…read more Entrance is free and there are shops up at the top. The views are amazing during the day and at night. There's an audio guide for purchase if you like but we just walked around and took in the ambiance and the views. A must visit if you're staying close by. After you're done enjoy one of the shops down below and take in all the glory Corsica had to offer.
