Magnificent routes to explore in the region

It's not hardcore, and I think three technical points are too many. There's a lot of elevation gain and a fair amount of distance, but no scrambling and no exposed sections. It's a fairly easy and beautiful tour for this altitude.

Magnificent pond in the hollow of the mountains, fed by the Mourguillou stream. Superb hike through the pastures in the jasse de Mourguillou.

Mérens-les-Vals is a rural commune of nearly 200 inhabitants located on the banks of the Ariège River, in the eponymous valley that connects Ax-les-Thermes to the Andorran border. The commune has long been known for giving its name to a breed of horse (the Mérens, small black-coated riding horses). Today, it enjoys a fine reputation as a stopping point on major hiking trails. Whether you're hiking the GR 10, 107, the GRP® Tour of the Ax Mountains, or planning a day hike, this small village tucked away in the valley is a must-see. There, you'll find a train station with regular service from Toulouse. Adjacent to the station, you'll find a pleasant bistro and mini-market. Stop by for a simple coffee break or a stock-up on food. There's no shortage of accommodation options. You can book a room or a gîte year-round. In summer, you can choose a campsite located on the left bank of the Ariège River, one kilometer north of Mérens, on the Chemin des Bonshommes, which is part of the GR 107 hiking trail.

The Estagnol pond culminates at 1,650 meters in the Mourgouillou valley. Headed by the Mourgouillou hut, the pond is an ideal resting place, both for the animals in the summer pastures and for walkers on a walk. If the summer is hot, dip your hands in it to cool off. Be careful to filter the water if you want to drink it: despite its sometimes crystalline colors, the presence of cattle brings bacteria that are not very appreciable for your stomach.

On the road to Mérens-les-Vals, the Mourgouillou hut is your last stop. It stands in an idyllic environment, ideal for taking a last break before Mérens-les-Vals. The small stone construction pierced with a door and a window is basic but has the essentials for a successful break. There is a fireplace and a side wall on which up to four people can sleep head to tail. For water and wood, the surrounding streams and woods provide the necessary. Your break is over, you only have one hour of downhill walking to reach Mérens-les-Vals.
