Renowned for its incredible crack systems, there is a predominantly **clean climbing ethic** in Valle Orco.
**Bolts** are often placed **for anchors & abseils**, but are otherwise strongly **discouraged where natural protection can be placed**.
Even so, there are a fair number of sport/bolted climbs in the valley. Talk to local climbers/guides before considering putting in bolts, **bolts are permanent**.
Some classics crack climbs, bolted in mania of sport climbing in the 80's/90's, have since had their bolts removed.
