The Pico Mulleres trail is considered difficult or hard mountaineering. It's a demanding high-mountain hike with significant elevation gain (around 1,400-1,600 meters depending on the starting point) and requires good physical fitness, sure-footedness, and prior experience in high-mountain terrain. While it's often called an 'accessible' three-thousander, it should not be underestimated.
The terrain is varied and characteristic of high-mountain environments. You'll traverse well-marked paths initially, which then give way to irregular, rocky, and block-filled areas. Expect extensive scree slopes, large granite slabs, and sections requiring scrambling. Depending on the season, you might encounter snowfields, even into late summer.
The recommended season for hiking Pico Mulleres is from July to September. During this period, snow conditions are generally more favorable, and the weather is typically more stable for high-mountain ascents. Outside of these months, specialized equipment like crampons and an ice axe may be necessary due to snow and ice.
Yes, the trail offers spectacular scenery. You'll pass by beautiful glacial lakes, known as ibones or estanhets, such as the Ibones de la Escaleta and Estanhets de Mulleres. You can also visit the Vielha Refuge (Vielha Hospice) and the scenic Molières Waterfall. The summit, Tuc de Molières, provides breathtaking panoramic views of the surrounding Pyrenees, including the northern face of Aneto and the Maladeta massif.
The Pico Mulleres trail is located within the Parque Natural Posets-Maladeta. Generally, there are no specific permits or entrance fees required for hiking the trails themselves. However, it's always advisable to check local regulations for any potential restrictions, especially concerning camping, fires, or specific access points, as these can change seasonally or due to environmental concerns.
While dogs are generally allowed in the Parque Natural Posets-Maladeta, it's crucial to keep them on a leash, especially in high-mountain areas to protect wildlife and livestock. Given the trail's difficult terrain, including scree and rocky sections, and potential snowfields, ensure your dog is fit and accustomed to such conditions. Always carry enough water for your pet.
The area is home to diverse wildlife. Keep an eye out for chamois (sarrios/rebecos), marmots, and various bird species, including golden eagles and even bearded vultures soaring overhead. Respect their natural habitat by maintaining a safe distance and not disturbing them.
Common starting points for the Pico Mulleres trail include Artiga de Lin or areas near Llanos del Hospital/La Besurta. Parking availability can vary, especially during peak season. It's recommended to arrive early, particularly on weekends, to secure a spot. Some areas might have seasonal restrictions or shuttle services, so check local information before your visit.
Yes, sections of this route overlap with several other official trails. You'll find it intersects with parts of the Étape 22, Aran Pirineos. Camino de Santiago, Ramat de Camins. Etapa 13 : Vielha => Refugi de Conangles, Setau Sagèth, and Tour de l'Aneto, among others.
Pico Mulleres is renowned as one of the most accessible 3,000-meter peaks in the Pyrenees, making it a popular goal for mountaineers seeking to conquer a 'three-thousander' without extreme technical difficulties. It's often a preparatory ascent for those aiming for Aneto. The trail offers a rich and diverse natural environment, moving through fir forests, alpine pastures, numerous glacial lakes, and providing exceptional panoramic views from the summit.
Given the trail's difficulty and high-mountain environment, sturdy hiking boots with good ankle support are essential. You should also bring appropriate layers of clothing for varying weather conditions, plenty of water, high-energy snacks, a map and compass or GPS device, sun protection (hat, sunglasses, sunscreen), and a first-aid kit. Depending on the season, trekking poles can be very helpful, and if snow is present, crampons and an ice axe may be necessary.
