There is a nice 2km loop around the citadel. If you walk this path you can see the old fort walls and a nice canal. While I was there for the first time I also saw some shaggy cows with long horns walking on the other side of the water. On a nice day this is PACKED. The path is so crowded it`s no longer a nice walk. There are also (as pretty much everywhere in France) people smoking everywhere. This was a huge turnoff for me as you really can`t go here for "fresh air."
