The peak Sobarcal or Petragème (2.259m) is located between Petrechema (2.371m) and Acherito (2.378m) and it’s a nice rocky spun with beautiful panorama. The peak has its own route across Foyas del Ingeniero but it’s normally climbed in the same day of Petrechema thanks to the easy connection across Puerto de Ansó or Col of Petrechema (2.084m).
The best face is the French (east) a very nice aiguille nearby of Aiguilles d’Ansabère but the route reaches the summit across its West face. The last meters have a little rocky-climb that’s very easy to mountaineers but it’s not for hikers.
For the spanish approach, start from the mountain hut of Linza (see SP page of Mesa de los Tres Reyes, route Linza). You will have to get there from Pamplona or Huesca, the biggest closer cities. Follow the road linking both of them (N-240) until the crossing of Venta Carrica. This is a crossing about (will check) sixty kilometers from Pamplona, where you can find a petrol station and the beginning of the road to Sigüés / Salvatierra de Esca / Roncal. Follow this road (NA-137) for thirty kilometers, until you get to Isaba. After Isaba keep going north (NA-1370) for three more kilometers and turn right on the crossing marked as (Zuriza /Ansó). This small road (NA-2000) will take you across the valley of Belabarce and to the camping area at Zuriza, under the Sierra de los Alanos. When you finish coming down from Belabarce (that will be some thirteen kilometers after Isaba), turn left for the camping area and drive around it until the end of the road. It is not in a very good state, so don't drive fast. You will see the dirt roads to Barranco de las Eras and Barranco de Gamueta to the right, but pay them no attention. Keep going on the main road until a final turn right, around a rocky hill, sets you on the small flat valley known as Plano de la Casa and the mountain hut of Linza.
The french access is made by the Vallée d'Aspe. You will have to turn right on the crossing marked "Lescun", as you drive up the valley from Oloron Ste-Marie. From the village of Lescun ( stunning views of all the peaks of the area ), follow the road to the bridge called "Pont Lamareich " ( ask local people, or better: buy french map scaled 1/25000 " Vallée d'Aspe ). That's where you leave the car. Afterwards, follow the obvious track westwards until a nice plateau where streams melt ( 1400m ). Views of Petrechema can be enjoyed at this spot. Get going leftwards, into the forest. At about 1560m you will find some huts, offering views of the Col de Petrechema. Steep but easy walk on screes and cobbles. At the Col de Petrechema (2080 m) turn left towards the summit of Sobarcal following the cairns.
No permits required.
The parking of mountain hut of Linza is small for the many mountaineers that come here on a sunny day for what it is advisable to get up early (or to sleep in the mountain hut the previous day). Linza is the point of beggining of many routes for others mountains of the zone.
Note for winter time: a lot of times the access to the summit has ice and it's no possible to cross it.
