You can go through and there is an exit, although you have to go over a fence; you can also return by the same path.

Most pilgrims go to the Cathedral of San Salvador and very few go up to the 35-meter-high sculpture of Jesus. There is a beautiful path from here to Ules, from where you can return to the Camino Primitivo. The view over Oviedo from up here is definitely worth it.
