Picos de Vallibierna (3,067 m)
Itinerary 1. Forest Refuge - Collado de Vallibierna - Picos de Vallibierna - Barranco de Culebras - Forest Refuge. (MBEA, S3-S4. 1067 m).
The active tourism allows you to enjoy unique landscapes surrounded by nature. The itinerary that we offer you ascends parallel to the Vallibierna river, leaving the Llosás and Tempestades route on the left, until reaching the Vallibierna lakes. Skiing descending along the same route is possible, although it is highly advisable to continue along the ridge to the next summit and complete the circular route with the impressive channel of the Culebras ravine.

Observations: it is a good viewpoint and the descent is very interesting. Impressive summit ridge, which requires you to take off your skis, and which includes the famous "Horse Pass" between the two summits (rope advisable). Direct ascent and descent of the Culebras ravine, a channel with a very sustained slope, is frequent.
Itinerary 2. Llauset Reservoir - Llauset Hill - Vallibierna Peak. (BEA, S3. 932 m).
You cross the Llauset reservoir or skirt it, depending on whether it is frozen or not, and in a westward direction you ascend to the obvious Llauset pass, south of the Vallibierna peak. Taking off your skis, you climb the ridge to the summit. The descent is carried out along the same route.
Observations: solitary and wild place. Access is quick, although it is advisable to make sure that the tunnel that leads to the reservoir remains open. The final ridge presents some IIº steps that, depending on level and experience, may require the use of the rope. The descent gradient with skis is somewhat reduced. Taking a certain detour, it is also possible to access the Vallibierna pass from the Llauset reservoir, to connect with the previous itinerary in its final part and thus completing a crossing route.
Pico de Castanesa (2,861 m)
Itinerary 3. Vallibierna forest refuge – Torrente de Estiba Freda – Collado de Castanesa – Pico de Castanesa. (MBEA, S4. 1067 m)

From the refuge you must cross the Vallibierna river using the best possible route and head without hesitation towards the Estiba Freda stream, which you must ascend. At first the passage is somewhat obligatory, but soon the valley widens and by clear and wide shovels the ridge of the chain is reached. The The summit is located further south, so a flank must be made until we end up traveling along a beautiful, flat and wide ridge, which takes us to the summit.
Observations: This is a privileged balcony on the southern slope of the Maladetas massif. It is an optimal journey for getting started in skiing or to spend days with more unstable weather, with a good descent through wide slopes. From the summit you can descend directly to Cerler, following a somewhat complex itinerary through the forest.
Russell Peak (3,205 m)
Itinerary 4. Vallibierna forest refuge - Pleta de Llosás - Pico de Rusell (BEA, S3, II. 1,255 m).
The itinerary ascends parallel to the Vallibierna river, along remains of a track, to turn left and along steeper slopes to reach the pleta and the lakes of Llosás. We continue skirting the rock barrier to the east and climbing in the direction of the Tempestades peak, looking for the obvious diagonal channel that, to the right and along an aerial and delicate route, leads to the summit of Rusell. The descent is carried out along the same route.

Observations: extraordinary summit, very isolated in winter and not very suitable for cross-country skiing yes It is compared to the neighboring Tempests. The final attack, long and delicate, requires the use of rope. The base of the ski tour largely coincides with the ascent to Tempestades peak.
Storm Peak (3,290 m)
Itinerary 5. Vallibierna forest refuge - Lagos de Llosás - Pico de Tempestades. (BEA, S3. 1,340 m).
The route ascends parallel to the Vallibierna river, along remains of a track, to turn left and along steeper slopes to reach the pleta and the Llosás lakes. It continues towards the east, skirting the step of rocks and snow at its weakest point, and then goes back in the direction of the Tempests peak. You cross an immense shovel, open and wide, to the vertical of the peak, which you gain by ascending on foot the last 100 meters, slopes for the boards but easy to overcome. The descent is carried out along the same route.

Observations: classic and highly recommended ascent, one of the best in the massif. Impressive panoramic view of the mythical Salenques-Tempestats and a descent to remember. The summit is reached without skis but with a good level and enough snow. possible to descend practically from the summit (S4, S5).
Margalida Peak (3,241 m)
Itinerary 5a. Vallibierna forest refuge - Llosás Lakes - Margalida Peak. (BEA, S3. 1,291 m).
The itinerary ascends parallel to the Vallibierna river, along remains of a track, to turn left and along steeper slopes to reach the Llosás pleta and then the lakes. It continues towards the east, skirting the step of rocks and snow at its weakest point, and then goes back in the direction of the Tempests peak. You cross an immense, open and wide shovel, to the point closest to the Tempestats-Margalida ridge. The ridge is gained by steep slopes and is followed with a delicate climb (IIº-IIIº) and very aerial to the summit (rope advisable). The descent is carried out along the same route.
Observations: rugged granite watchtower that can only be reached by crossing the sharp ridge that connects it with the Tempestades. The difficulty is enough of a deterrent for the majority of skier-mountain climbers to settle for the ascent of the neighboring Tempestades. The ski route coincides practically in its entirety with the ascent to the Tempestades peak.
Aneto Peak (3,404 m)
Itinerary 6. Vallibierna forest refuge - Collado de Coronas - Pico de Aneto. (MBEA, S3. 1,404 m)
Ascend, from the Vallibierna refuge, through the Coronas valley, very suitable for traveling with skis. The main difficulty lies in accessing the Coronas pass, which will require taking off your skis and climbing over blocks and a steep snowy slope. Once there, follow the normal route to the summit. Descent along the same route.

Observations: Interesting ascent through wild terrain with a great atmosphere. It is a demanding route and less common than the normal Renclusa route. Both access to the Coronas pass and the Mahoma pass require taking off your skis and depending on the conditions, some considerable difficulties may arise. An interesting variant consists of reaching the summit through the Estasen corridor (45º). In good conditions it can also be descended (S4, S5).
Itinerary 7. La Renclusa Refuge - Upper Portillón - Aneto Glacier - Aneto Peak (MBEA, S3. 1,264 m)
You leave the refuge in the direction of the Los Portillones Ridge, climbing a steep slope of more than 600 meters of altitude. You then turn south until you find the pass, at the possible to descend practically from the summit (S4, S5).
