Whats the scene in Catalonia like

How easy is it to find partners in siurana, margelef, rodellar or terradets. Is the scene kind of like Thailand or potrero were you can go solo and meet climbing partners fairly easy. Are the campgrounds community based were everyone hangs out together or do most people stick to themselves. I really want to do an extended trip to northern Spain but don't have a motivated partner to go with. Any info is appreciated
