Wye valley offers some fine limestone climbing (both sports & trad) and plenty of hill walking options.
Staying at Beeches farm campsite, one of very few campsites in UK that allow open fires & BBQ.

Uninterrupted views of the valley come as standard :)
Only two hours drive from London, the campsite is conveniently located close to Shorn cliff and Offa's Dyke path.
Ancient Forest of Dean and winding river Wye provides a great backdrop to the climbing.
Leaving on Friday evening and returning on Sunday afternoon.
