At the West exit of Jaca (towards Pamplona), at the petrol station traffic circle, head for Bernues via the Puerto de Oroel route A-1205. After 6.5 km, turn left onto the tarmac track leading to the Mirador de Oroel. Park in the Mirador car park; if you don't have enough space, continue a little further along the track, where there are parking spaces in the shade. This is no problem, as the return journey is via this track.
(S/E) With your back to the viewpoint, take the wide trail that begins on the other side of the track. This path twists and turns to reach the ridge.
(1) At a hairpin bend, arriving from the left, a narrower path joins the upward path. Follow the signs for "Cruz de Oroel", staying on the main path.
(2) At the Peña de Oroel crest, you'll find a signpost. To the West, there are two paths to the Cross. Take the one nearest the crest on the right to climb to the summit. The one below the ridge will be used on the way back. Climb towards the clearly visible cross.
(3) Pass the junction for the return path and continue to the cross.
(4) At the Cruz de Oroel (1770 m), the highest point of this hike, you can continue towards the western end of the ridge for 200 m to enjoy the view. Beware of the emptiness all around you.
(5) Retrace your steps and return to the cross.
(4) Continue along the same path for about 400 m.
(3) Bend right to take the path below. After approx. 700 m, ignore a start on the right towards the Ermita de la Virgen de la Cueva, and return to the signpost.
(2) Head in the direction of Punta Bacials, which is the Eastern end of the ridge. The path first rises over a rock to join the ridge, then passes through Punta de Sora and follows the ridge to a fork. On your left, at the very beginning, on the North-facing slope, you'll see some snow pits. Continue along this well-marked path towards Punta Barcials.
(6) At a collet marked 1645 m (cairn), there are two barely-marked paths. Take the one on the left and, after about 300 m, the path flattens out. Leave it and head right, due South, off-path, towards the summit, which can be seen a few dozen metres away (cairn).
(7) From the summit, you can see the whole of the 3.8 km ridge we've covered. Take the path below the summit due West and return to the collet.
(6) Turn right onto the Senda de los Lobos (Wolf Trail), on the North side, which begins with a steep descent for a few dozen metres, then turns North-West for 1.2 km to reach a junction of four trails.
(8) At first, you'll see a trail coming up below you, then about fifty metres further on, a Y. On the uphill left is the continuation of the Senda de los Lobos (Wolf Trail), which joins up almost level with the original itinerary at the initial junction, and on the downhill right is the path we'll follow to rejoin the trail. The descent becomes steeper, then the wood becomes lighter and the slope less steep. Stay on the better-marked path and join the tarmac track.
(9) Take this track slightly uphill to the left and after 1 km, join the Mirador car park (S/E).
