Ascent to the Bisaurín in the Aragonese Pyrenees

The ascension to the Bisaurín at Aragonese Pyrenees It is a route that we have done on multiple occasions with the bad fortune of always having bad weather. In the end this bad streak ended and we were able to raise it with visibility and great weather, except for the little snow we found for the date we were in, the end of December.

Ascent to the Bisaurín in the Aragonese Pyrenees

End of December and we are facing a beginning of winter with very little snow. Sierras such as Guadarrama, Gredos or Sierra Nevada, are almost bare of snow and the few precipitations that arrive are in the form of rain due to the unusual temperatures at this time. Pyrenees seems to have saved a little, even so the accumulated snow It is not by far the same as in other years. This is one of the reasons why we decided to move here to undertake the ascension to the Bisaurín.

Lizara Shelter

After arriving at Lizara refuge about 9:00 p.m. and overnight peacefully in it, we got up at 07:15 since breakfast started at 07:30. The time is not bad since most of the mountaineers make the ascent to the Bisaurín in more or less 6 hours (round trip), therefore you can take advantage of the daylight from the zero minute and climb without hurries or burdens.


We take the track that goes right behind the shelter and that at the beginning is divided in two, taking the one that goes to the right in the direction of Gabardito refuge for the GR-11. This quickly takes a steep slope to the diversion of the Ordelca refuge which we will ignore and continue along the GR until a long esplanade that will end up zig zag until the Foraton Neck, a port that separates the two valleys.

Going up to the Foratón Neck

The zig zag is a bit messy because we will see a multitude of variants which in some cases no matter how clear the path may seem we will have to forget and take what seems most direct to the Bisaurin.

High Strut of the Foratón

Once in the Foraton Neck we turn sharply to our right at 90 degrees, climbing the mountain ridge, leaving the summit of the High Strut of the Foratón of 2154m and right in front of our eyes we will have the Bisaurin and its 2670m high.

Ascent to the Bisaurín

This steeply inclined ramp is usually loaded with snow even well into the summer, so take precaution since it half-way tilts considerably becoming very hard physically. It is practically a non-stop climb from 2016m to the summit of the Bisaurin, without any loss provided visibility is good.


Once at the summit, at 2670m high, we have great views of the national park of the Western Pyrenees in France, the valley of Done in Spain and even a colossus like the Midi d'Ossau.

Ascent to the Bisaurín

Taking our well-deserved rest, we descend the ridge in the opposite direction (West), having to make a continuous rise and fall quite beautiful and with little difficulty.

Ascent to the Bisaurín

The crest is a real show and deserves to be taken very calmly. Look where you look at the views are fabulous and the weather we were doing was great, not a hint of wind.

Ascent to the Bisaurín

We will arrive at the base of Alto de Fetas about 2450m high where we turn sharply north and start down a narrow channel at the beginning and then widens to 2300m high.

Ascent to the Bisaurín

It is these points where we must exercise caution since there are areas where we will find ice in winter and the slope is a bit more inclined. Once at 2300m we turn to our right down the only possible side and from where you can see magnificent views of the Paul of Bernera, which gives its name to the mountains.

Ascent to the Bisaurín

To get to it you have to go through the occasional shovel completely frozen in winter and where a fall can be fatal. Beware of it. Once the bad drink is over we will arrive at the forecourt mentioned above where we can stop and enjoy the wonderful views of the Punta Alta d'a Portaza, Punta Baxa d'a Portaza and Punta d'l Aguila.

Ascent to the Bisaurín

To get to Paul from Bernera It will seem like a great place for cross-country skiing, due to its size and low inclination. A place where a lot of snow usually accumulates and that many people choose as an easy route from the Lizara refuge ...

Cubilar de Bernera

From this point and following the right side of the esplanade, we will take the path that will go to our right quite evident and that takes the path of a river to the refuge of the Cubilar de Bernera. Now it's only time to go down and down ...

Ascent to the Bisaurín

Already going down the Barranco de Bernera, the slope of descent begins to fall rapidly until we reach the Ordelca refuge and from here we cross again with the GR-11. The path that takes us directly to our starting point, the Lizara refuge.

Practical data Ascent to Bisaurín

When to go?

The ascent is viable all year round, but during the winter it is not recommended for inexperienced mountaineers since it requires the use of mountain material such as crampons and ice axes, which must be known to use correctly.

How to get?

We must reach the town of Aragües del Puerto, whose detour is a few kilometers before reaching Done. Once in the village we follow the road for another 10 kilometers to the Lizara refuge where the road ends

What to wear

Being a winter route we must take our ice axes, crampons and helmet given the inclination of many points, as well as some delicate steps. These elements are essential especially in the steep descents from the Bisaurín to the Paul of Bernera, or if you do it in the opposite direction, from the Bisaurín to the Foraton Neck.

Where to sleep?

We have the main shelter in the parking lot called Refugio de Lizara and on the way we have several shelters without a guard, especially in the direction of Paul of Bernera.

If you follow our route you have the way and in this order, the Fetás shelter 45min from the parking lot, the Cubilar de Bernera very close to the Paul de Bernera and the Ordelca refuge just 20 minutes from Lizara Shelter If you go to the Paul.
