Meeting up with the Guide in Boí Taull. Transfer from Boí Taull by taxi to Planell d’Aigüestortes. Many lakes and their human use will accompany us during today’s stage. After leaving the Llong refuge behind and ascending, first through the forest and then through large Pyrenean meadows to the Dellui pass (2,577 m), we will skirt or pass very close to the Eixerola, Cubieso, Mariolo and enormous Tort lakes. Finally, we will walk along the path of old wagons for loading the material in the works of all these dams. We will spend our second night in the Colomina refuge next to the lake of the same name at 2415m. Dinner and overnight at Colomina Mountain hut.

Breakfast. Today the stage is shorter, but it is worth sleeping in the Josep M. Blanc Refuge, one of the best-attended mountain huts in a spectacular setting. We begin by going up a slope and short canal, ending with some stairs to Pas de l’Ós; surrounding the Saburó lake, we will climb the hill of the same name, at 2667 meters. Here we deviate from the usual itinerary to go up to the Tuca de Saburó (2,906m). Now, we will walk downhill until the end of the route, enjoying the last area with postcard forests and more lakes to reach the idyllic refuge, Josep María Blanc, on a peninsula within the Tort de Peguera lake. Dinner and overnight at Josep M. Blanc Refuge.

Breakfast. We will enjoy the lush and extensive black pine forests near the Ernest Mallafré refuge during this day. On the other hand, the Sant Maurici lake and the relief of Els Encantats make up the most recognised image of the national park. To make the route between the Josep María Blanc and Ernest Mallafré refuges, we will choose the variant that passes through the Monasterio pass and runs through the rural valley of the same name. Dinner and overnight at Amitges Refuge.

Breakfast. On this route, we will admire the wild, lonely and sparsely vegetated landscape around the Amitges refuge and the spectacular and vertical needles of Amitges next to the shelter of the same name. After that, we will go through the magnificent glacial cirque that baptises the refuge of Saboredo. After reaching Saboredo mountain hut, we will cross the glacier circus of Colomers, surrounded by peaks between 2,700 and 2,900 m in altitude, which is among those with the most lakes in the Pyrenees. Dinner and overnight at Colomers Refuge.

Breakfast. The stage starts with the ascent to the mountain pass of Caldes, with almost 2600m, and the Crestada pass to reach the Restanca Refuge, where it is possible to find marmots. Then, we retrace our steps until Coll de Crestada pass and descend next to the Monges, Mangades and Travessani lakes, reaching the Ventosa i Calvell refuge (2273 m), with beautiful peaks surrounding us, such as the famous Montardo. Another magnificent sunset with amazing views. Dinner and overnight at Ventosa i Calvell Refuge.

Breakfast. The most iconic climb of the trek, to the Contraix pass, the highest point of the route at 2,748 meters, awaits us as soon as we leave the refuge. Large blocks of rocks and magnificent views await us on the other side of the pass, where after a long descent of about 900 meters and more lakes, we will arrive at Estany Llong. After a few days of enjoying sunsets and sunrises in high mountains, far from inhabited areas, the trek is done. Transfer to Boí Taull and end of services.
