In reply to dsauerbrun:
Enough poeple in Rodellar in summer?! Summer is the prime time to go to Rodellar. You will have problems finding an available route! So I am sure you will find a partner there.
No need for car you just walk between 5 to 20 minutes, depending on the sector.
You only climb 6a/6a+?!!! Go somewhere else. Rodellar is probably one of the worst places in Spain to go if you only climb that hard. You have very little choice of routes and the ones you have are completely worn out... and there will be a big queue to try the route! In my opinion it is only worth it to go to Rodellar if you climb 7b or harder. But I have friends that disagree with me.
If considering other nearby places for summer, then try Cavallers. So much better, but you need a car to get to the dam.
