The first section of the Senda Pirenaica (Pyrenean Trail) – see this Collection: komoot.com/collection/1991393 – takes you through the rolling mountains, green meadows and endless beech forests of the Basque Country and Navarre. This second section enters the spectacular Aragonese Pyrenees, where you find the highest peaks of the entire mountain range. This demanding route contains some of the most beautiful stages and some of the most memorable mountain scenery of the entire GR 11.
The rewards for hikers who dare to brave the steep gradient of this route are many: glacial lakes that hide below spectacular cirques, deep, verdant valleys, windswept and panoramic high passes, lush alpine forests and majestic peaks of over 3,000 metres (9,800 ft). As if that weren’t enough, the route crosses a large part of the Ordesa y Monte Perdido National Park, as well as the Posets-Maladeta Natural Park. The former is home to what is possibly the most spectacular waterfall in the whole Pyrenees, the Cola de Caballo. Meanwhile, the second hosts the highest peak in the entire range, the Aneto.
In total, the Aragonese section of the GR 11 covers some 250 kilometres (155 mi) and almost 14,500 metres (47,500 ft) of elevation gain. It’s admittedly quite a challenge to overcome in 14 difficult yet magical stages. Most of the days, the challenge is solely down to the distance to cover and the elevation gain to overcome. However, pay attention to the highest points of the route, where there can be snow until well into the summer and where there are sections of loose rock. Depending on the snow conditions, some sections may require the use of ice axes. In any case, having decent fitness and some experience in high mountain routes is necessary to successfully complete this itinerary.
Although some stages end in small villages, you’ll mostly stay in mountain huts. These are sheltered refuges, which generally offer breakfast, lunch and dinner, as well as other amenities for a comfortable stay. Be sure to book in advance and check opening hours and available services to avoid disappointment. Along the way, you'll also find small free shelters and huts where you can seek refuge in case of a storm or other emergency.
There are several points along the route where you can collect water, generally from streams, lakes and some springs. As for food, many huts offer half-board service and picnics to take away. The route also passes through some villages with supermarkets, but they are few and far between.
The best time to do this route is in summer, when weather conditions are more stable and there is less chance of snow. Even so, I advise you to check the weather before setting off. Don't forget to bring warm clothes, even in summer. In addition to good boots and a comfortable backpack, you should also bring a sleeping bag.
To get to the starting point, the Zuriza hut, the only options are on foot if you are coming from the Navarre section or by taxi from Ansó. From the Conangles refuge, where this adventure ends, you can take a bus to Vielha or to Barcelona.
I hope you enjoy what’ll undoubtedly be one of your most unforgettable high mountain experiences!
