All this enlivened with a welcome drink and local gastronomic products.

DAY 2 / STAGE 1

Refugi de Conangles - Hotel Balneario Caldes de Boí

  • 14.04 Km
  • +1570m/-1640m

In the first stage of the route we will start, as early as possible, from the Conangles refuge in the Aran Valley and we will go all the way up the Besiberri Valley, entering immediately into the Alta Ribagorça region.

During the ascent, we will enjoy the different lakes and the impressive glacial cirque crowned by the well-known ridge of the Besiberris. Through a slightly decomposed chimney we will gain the col d'Abellers from which we will have the Besiberri S already very close.

From the summit, we will descend to Caldes de Boí through the valley of Llubriqueto and the beautiful lakes of Gémena. Overnight in comfort at the Hotel Balneariode Caldes de Boí complex.

DAY 3 / STAGE 2

Caldesde from Boí-Presa de Cavallers - Ventosa i Calvell Refuge

  • 11.7 Km
  • +1700m/-905m

Approach to the Cavallers dam from Caldes de Boí by the path, without the need of a cab. It will take us almost an hour.

After a night of comfort in Caldes de Boí, approach to Refugi Ventosa i Calvell passing by Punta Alta de Comalesbienes, adding the easternmost 3000 meters peak of the Boí sector.
‍
Taxi option available to Presa de Cavallers, see comfort option.

‍‍COMFORT OPTION

Approach to the Cavallers dam from Caldes de Boí by cab.

After a comfortable night in Caldes de Boí, a quieter day approaching the Refugi Ventosa i Calvell by the usual access to the refuge. It runs along the left bank of the Estany de Cavallers and from the pleta of the Riu Malo, the road goes up progressively until you reach the refuge, in a slightly higher location with respect to the Estany Negre, at the foot of the impressive Comalespada and Punta Alta further back.

DAY 4 / STAGE 3

Ventosa i Calvell Refuge- Restanca Refuge

  • 5.20 Km
  • +415m/-606m

The third stage is less demanding in terms of distance and elevation gain. We will leave the Refugi Ventosa towards the Estanys de Tumeneia, bordering them to the east and take the path that ascends to the Tumenia pass. The descent to the Refugi de Restanca is done without difficulty from the pass.
‍
Peyta-Besiberri Gap Variant N

From the Ventosa refuge skirt the Tumeneia Lakes to the south and continue towards the Collet des Isards to reach Brecha Peyta. This is a difficult navigation route. You must be very attentive to not miss the milestones.
‍
If we are prepared, experienced and have the right equipment, before Brecha Peyta we can take a temporary detour to reach the Besiberri Nord. For this stage we can hire a mountain guide (check availability and prices with the organization).

From the vicinity of Brecha Peyta, depending on the weather, conditions and skills of the group, you can complete the ascent to Besiberri N (PD+, III obligatory, recommended rappel), and return to the same Brecha Peyta to continue with the stage.

From Refugio Ventosa to Refugio Restanca
‍Distance: 5.20 km. Elevation gain: +415 -606.

‍FromRefugio Ventosa to Refugio Restanca, summiting Besiberri N
‍Distance: 11.80 km. Elevation gain: +1110 -1185.

DAY 5 / STAGE 4

Refugi Restanca - Vielha Hotel Riu Nere

  • 19.40 Km
  • +1095m/-2085m

This fourth stage is the longest but has a contained slope and runs through better terrain for walking than the previous days. We leave the Refugi Restanca to go up the Val de Rius to the Rius Lake. Here we leave the mythical GR-11 to gain the gentle Coret del Redon where we discover magnificent views over the Redon Lake and the Tuc deth Pòrt de Vielha, with the spectacular backdrop of the Molières or Mulleres, the Aneto and the Maladetas.

After crowning the aforementioned Tuc deth Pòrt de Vielha, we "only" have to descend to the Pòrt de Vielha and reach the town of Vielha. Today we can enjoy a very comfortable accommodation and the atmosphere of the beautiful town of Vielha.

DAY 6 / STAGE 5

Vielha-Refugi Artiga de Lin

  • 16.5 Km
  • +1529/-1047m

In the penultimate stage of the route we will leave Vielha to Artiga de Lin. The day begins with a vertical kilometer on a well-marked trail to reach Montcorbisson and Tuc de Letassi. We descend by a grassy and less marked trail to Eth Santet. From this wide pass we turn right to the west to continue down the ravine to the Cabana de Gèles from where we take a well-marked trail PR-C 115 to the Cabana de Gaussac (take this path to our left). 

We continue along the PR-C 115 until we enter the forest of firs and beeches, first on flat and slight ascent to finish with a steep descent to La Artiga de Lin at the height of the Hermitage. Here we can take the track and continue along it to the shelter or take the path that leaves the track and make the last climb through the forest cooler until the end of the stage.

DAY 7 / STAGE 6

Artiga de Lin Refuge - Conangles Refuge

  • 16.35 Km
  • +1585/-1510m

Last great effort that requires getting up very early in this last stage of the route that begins with a beautiful ascent in crossing the Tuc de Molières or Mulleres. Starting from the Aranese refuge of Artiga de Lin, on the Atlantic slope, we gain the Còth des Aranesi to climb the last meters of the Molières on the slope of the river Ésera in the Aragonese Ribagorza. 

Once the summit is crowned, we descend the slope of the Noguera Ribagorçana, again in Aranese territory, to the Conangles refuge located in the lush beech forest of the same name and at the entrance of the Besiberri valley. 

Be very attentive to the Molières approach.

The route was a great experience, and the excellent organization behind it—especially with the self-guided option—gives you the peace of mind you need to focus solely on enjoying the mountains. You don’t have to worry about booking mountain huts, maps, GPS tracks, hazardous areas, etc.—you can just enjoy yourself, knowing that if any problems arise along the way, they’ll be there to help. It’s been fantastic to discover these areas of the Pyrenees (Los Perdidos and Moliere-Besiberris) with them and in this way.

Patricia and her team at La Alta Ruta were wonderful to work with. They helped us plan and book a customized 9-day trek along La Alta Ruta de Los Perdidos, made the refuge reservations, assisted us with transportation to and from Bujarueles, and provided accurate information and GPX tracks for the trail. They were responsive, knowledgeable, and reliable. The background essays they shared in weekly emails before the trip deepened our appreciation of the route’s geology, history, and culture. With their GPX files, paper map, and brief orientation meeting, we completed the route on our own, never needing to contact them during our trek—though we were reassured to know we could reach out if we needed help during an emergency in a foreign country. We’ve planned many of our own backpacking routes, but it was helpful and important to have their experienced guidance regarding what was unfamiliar, foreign territory for us. There are trail junctions with alternative routes that present different challenges, levels of exposure, or views. And while we were often on clearly defined and well-maintained trails, at other times the trails were more primitive—somewhat like being on a well-established cross-country route in the U.S. wilderness but with trail markers and more cairns. The Alta Ruta de Los Perdidos is as beautiful and challenging as described in other online trip reports and reviews. We are experienced backpackers in our 60s who are in good physical condition but are not competitive athletes. On our 9-day itinerary in early September 2026, many days were pleasantly long and tiring, but we built in some easier days that gave us time to take a break from the bustling refugios at a hotel in Gavarnie, climb a peak, take a day hike on a side trail, or simply savor a fantastic view and a beer at a picnic table outside a refugio. We found the refugios to be a fun contrast to our usual, much more isolated backpacking at home. We made a lot of new friends from Spain and other countries. We still had plenty of peaceful time in the mountains to ourselves during our days on the generally uncrowded trails. There was drinking water at every mountain hut. But because these trails have been used by sheep and cattle herds for centuries, when we refilled our bottles from streams or springs during the day, we both filtered and treated the water, as La Alta Ruta advised. I highly recommend this route and working with La Alta Ruta to plan a self-guided trip. And judging by the very happy hikers we dined with one night—who were with one of La Alta Ruta’s local guides—I’d also recommend their guided tours if that’s your preference.

Everything was great; our guide, Toño, was very helpful throughout and very knowledgeable. I really enjoyed both the guide and the rest of the group. I'll be back next summer to do the entire Alta Ruta.

In my case, the Alta Ruta de Molieres y Besiberris. A demanding route with technical sections that aren’t suitable for everyone. Top-notch organization: briefing, GPS tracking in case of any serious mishap or emergency, comprehensive information in the days leading up to the trip, daily monitoring, a phone line that answers any issues, alternative routes in case of bad weather, and services included at every overnight stop (mountain hut or hotel—and by the way, it’s a great idea to spend two nights in hotels); in other words, they take care of everything, and all you have to do is focus on the hike and enjoy “paradise.” A very secluded but incredibly beautiful route, covering three 3,000-meter peaks, with options to tackle a couple more along the same route. I’d do it again in a heartbeat!!! Thank you so much for everything!!!!
