In reply to bonebag:
Access is an ongoing issue at most of the Leics crags but there's plenty that's worth a look!
Slawston Bridge was one of my favourite ways to spend a summers evening when I was at Uni in Leicester, it's way better than going down the wall.
Craig Buddon is cool, access sketchy but keep a low profile and it's ok.
The Brand is absolutely brilliant- go there! Feels so weird ringing to get permission but they're lovely people and the house and garden are worth the trip by themselves.
Hangingstone Quarry has great climbing but a terrible access situation. Once you're in the quarry you'll never get caught but crossing the farmers field is a bit nerve racking. Try not to walk down the road to the crag obviously looking like a climber!
If you boulder hard Forest Rock is great and no access issues. Very limited below V6/7 though.
Hope you enjoy it!
