Lake Estaëns Trail

The circular hike to Ibon de Estanés typically starts from the Sansanet car park. This car park is located on the French side, just after crossing the Somport Pass. It's the primary access point for this route.

This route is generally considered of moderate difficulty. While it covers about 11.6 km with an elevation gain of around 738 meters, some sections can be strenuous, especially uphill climbs after the forest and potentially exposed areas like the 'Pas de l'Echelle'. It's suitable for hikers with some experience.

Hikers typically complete this circular route in about 4 to 4.5 hours of moving time, not including stops for breaks, photos, or enjoying the views. The total duration can vary based on your pace and how long you spend at the lake or other points of interest.

The trail offers incredibly diverse landscapes. You'll start by ascending through the lush Hayedo de Sansanet, a dense beech forest. After exiting the forest, the path opens up into the scenic Espélunguère valley with meadows and grazing livestock. The final ascent leads to the stunning glacial Estanés Lake, surrounded by alpine scenery. The return journey often provides panoramic views of the Pyrenean peaks.

Key highlights include the beautiful Hayedo de Sansanet beech forest, the open Espélunguère valley with its shepherd's cabins, and of course, the breathtaking Estanés Lake itself. You'll also encounter stunning View of the Pyrenean Peaks throughout the hike and pass by the Anglus Cabin.

The best time to hike this trail is typically from late spring to early autumn (June to October). During these months, the weather is generally more stable, and the trails are clear of snow. Early summer offers vibrant greenery and wildflowers, while autumn brings spectacular colors to the beech forest.

Yes, this trail is generally dog-friendly. However, since it is located within the Pyrenees National Park, dogs must be kept on a leash to protect wildlife and livestock. Always ensure your dog is well-behaved and that you carry out any waste.

As this trail is within the Pyrenees National Park, there are specific regulations to follow to protect the natural environment. While there are no entrance fees for the park itself, rules include staying on marked paths, not disturbing wildlife or plants, and keeping dogs on a leash.

It also intersects with the Sentier des Forges d'Abel au Sansanet PNP and the GR11 - Sendero al Ibón de Estanés, among others.

The 'Pas de l'Echelle' section is noted as being a bit more exposed, though still manageable.
