Rucu Pichincha is one of the three major peaks comprising the Pichinchas (the others being Guagua Pichincha and Padre Encantado). The mountain is NOT safe to climb directly from Quito because the route passes close by a poor area where robberies (and rapes) - even of groups - are known. Probably it is safe to go along the ridge the other side from Guagua Pichincha and then descend away from Quito.
