Feel free to get in touch
have a look at
Crags:
http://en.belclimb.be/home_rock_climbing.asp
Freyr is the biggest & best but a bit polished in some areas - you'll have the most fun from f6a up
Beez, Commando Camp, Mozet, Landelies are all about 30-45 min drive
Yvoir approx 50 min & Freyr 1 hour
Walls:

Current best wall in Brussels is New Rock, then Stone Age but most are worth visiting
Yep - leading at walls is rare. As said above Klimax at Puurs (was there Sunday chatting to Anak Verhoeven - she is seriously good) and Blocry at Louvain-la-Neuve (routes you can lead are normally min 5c)
Berdorf is excellent - no permit system anymore but you need to be a member of a UIAA affilated club (same goes for Belgium - at Yvoir & Durnal someone will probably check)
Next nearest crags are Nideggen, Bleau, Les Andelys, SudPfalz, N & S Vosges, stuff round Dijon,...
Driving to Cham takes approx 8:00 (no stops, no traffic) and is cheaper via Switzerland
Nearest skiing is S.Vosges
