The fortress is open 7 days a week, every day of the year. There are informative posts, in English, around the fortress to accompany tourists during their visit however, guided tours of the Citadel of Blaye are also available. Tourist guides will explain what life was like in a 17th century garrison and how Vauban envisaged his defence system. You can even discover the underground passages that soldiers would have used in case the fortress was besieged.
The citadel has a small population living inside, as if it were a village surrounded by think, protective walls. You will most probably enter the Citadel by Porte Dauphine and climb up the stairs to reach the Clock tower. From here you can walk along the top of the walls and enjoy a splendid panoramic view of the town of Blaye and the estuary of the Gironde river. Looking south, you can see the island Pâté and, on the other side of the river, Fort Médoc. Looking north, you can see Ile Nouvelle. At the end of your wall-top tour, you will end up on the highest part of the citadel, in front of the ruins of the Castle of Rudel which dates back to the Middle Ages.
