The ¿Reserva de la Biosfera? route is a sport climbing route made of exceptional itinerary and rock quality. It may lose some of its charm because of the fact that the difficulty is very concentrated, especially in the first pitch, but it's still a good project for strong climbers. The third pitch is a little gem. The route is almost completely equipped, although the anchors get farther apart in the easy sections. It's possible to abseil down with a 60 m rope, but it's preferable to use a 70 m rope.
