I just had my bicycle stolen during daylight hours on the campus of the University of Toulon. They cut through the lock. Unfortunately it was very good bicycle that I rented from a local bike shop and they gave me a so-so lock. After speaking with faculty and students from the campus, I learned that this happens frequently and they have also had computers stolen from their offices.
In places like the destal you get easily lost so make sure you go with someone who knows the area! Don't think about climbing if you don't have the good equipement, the place can be dangerous
