I've just gotten back from a few days sport climbing and bouldering in Lower Silesia, Poland (Sokoliki and Rudawy Janowickie). I'd rate this location 5/5 for a few reasons.
First, there are 100's of excellent routes densely packed (from 4 up to 8b; mostly granite).
Second, it is extremely cheap (beer is approx £1 a pint).
Third, the scenery is breathtaking.
While some of the crags are a little busy on the weekends, during the week we had many all to ourselves.
One of the highlights was climbing the 26m route 'Power of Love' (6c) on 'Skalny Most,' a stunning rock bridge. I didn't get it clean, but I'm not much of a crusher and I've been climbing less than a year.
Anyway, I made a very short film about our recent trip so you'll get some idea of how beautiful it is. Definitely, a place to consider visiting!
