Departure from Siguer (Ariège)
A magnificent but very demanding circular route with highly varied landscapes and terrain:Numerous waterfalls during the ascent, which is at times steep and very stony, up to the Peyre bridge.A short, slightly vertiginous ledge section to reach the vast Gnioure pond.A long path running alongside the lake, then the stream, and winding its way into the valley.A hillside climb that starts off fairly gentle but ends up quite steep, leading to the Étang du Rouch.Cross the pass and enjoy a gentle descent towards the very pretty Llassiès lakes.A challenging descent via a chimney (which can be bypassed via a hairpin bend) into the valley.A long and gentle descent (very long) via the Peyregrand and Brouquenat lakes from above.A gruelling descent along stony paths back to the car park.
The route follows the streams of Escalès, Auruzan and Gnioure on the ascent, then those of Llassiès, Peyregrand and Brouquenat on the descent.

Departure from Siguer (Ariège)
A very long descent crossing the delightful Llassiès Ponds and the valley of the Peyregrand Pond. The first section is fairly gentle and idyllic across a plateau, allowing you to explore all the Llassiès Ponds. This is followed by a very beautiful but challenging descent into the valley (Jasse de Bélesta) via a steep section with an exposed grassy chimney, followed by a long, flat stretch to the peaceful Étang de Peyregrand and a more demanding descent to the Jasse des Planes. The final section consists of a flat path to the Pont de la Peyre, followed by a descent lined with waterfalls, which is quite strenuous due to the rocky and stony terrain.
