In reply to timmr002:
As a few others have said - if there was anything any good, we'd have found it by now! The only worthwhile options are:
Brookes
Iffley (needs OUMC membership)
Horspath (though I'm stretching the definition of 'worthwhile' there)
The Oxford Boulder up in Blackbird Leys (ditto)
Then a bit further afield you could try Compton Verney, but I have no idea of what the access arrangements are these days. Cleeve Hill is a bit more than an hour away and can provide half a day's distraction.
Look on the bright side - if you were looking for somewhere to live that had relatively easy access to as many different climbing areas as possible, you'd end up somewhere about here. There aren't many places that are < 3 hours to the Peak, Avon, Cheddar, Swanage & Portland, Wye, Gower, and Dartmoor...
