In reply to samparsons:
All of the popular crags in Catalunya are, well, popular, with climbers from Europe and the States. Wouldn't be hard to find someone to climb with even during the week at Siurana, Margalef, etc. Might be a bit tougher on some of the small crags around Lleida tho. Maybe worth putting out an ad on Mountain Project in case any travelling Septics want to hook up.
