Things to Do in Ax-les-Thermes: Summer & Winter Activities

Ax-les-Thermes isn’t just a spa town — it’s also an ideal base for exploring the Ariège Pyrenees, in every season. Just minutes on foot or by a short drive from Studio Natik, this small valley packs in a genuinely wide range of outdoor activities: waymarked trails for hikers of every level, mountain bike routes from easy greenways to one of cycling’s legendary climbs, gorges to descend by canyoning, natural rock faces to climb (roped or secured via ferrata), rivers and mountain lakes to fish, and — come winter — three ski areas plus Andorra within easy reach. Below is an overview of each, with a link through to full details, distances and practical information for every activity.

Six waymarked routes fan out from the valley, ranging from an easy 3.9km family loop around the Lac de Campauleil to a full-day, 17km trek up to the historic Forges d’Orlu with roughly 1,000m of elevation gain. Whichever fitness level you’re planning for, there’s a route that matches it rather than a one-size-fits-all trail. See all hiking routes →

A flat, family-friendly greenway follows the river for an easy ride, while serious cyclists come specifically for the Col de Pailhères — an 18.6km, 1,281m-vertical climb often mentioned in the same breath as the Tourmalet. A 35km village loop and downhill bike park tracks sit between these two extremes. See mountain biking and cycling routes →

Three gorges, three very different experiences: a 2h30 discovery route suitable from age 8, a 3h30 intermediate descent with jumps up to 8m, and a 5-hour sporty route reserved for those in good physical condition. Always guided, always with proper safety equipment. See canyoning routes →

Just 7km from Ax-les-Thermes, Parc Akrobranch d’Orlu combines via ferrata, climbing and treetop adventure above the Orlu canyon, with courses graded by age and level — a summer shuttle even connects the park to Ax-les-Thermes. See via ferrata details →

An official no-kill stretch is designated on the Oriège river, in the commune of Orgeix, alongside the mountain lakes of Gnioure and Naguilles and a classic river-fishing section on the Ariège itself — enough variety that a week here doesn’t mean fishing the same stretch twice.

Entreserres, the official site listed by the tourist office, covers grades 4a to 6c and suits beginners well; Bonascre and En Castel suit more experienced climbers after a bigger challenge, while the Piscine site offers very easy access, ideal for a family. See climbing sites →

The small black horse native to the upper Ariège valley, saved from extinction in the 1970s, can be ridden today just outside Ax-les-Thermes. At Haras des Cimes, in Orgeix, options range from a one-hour discovery ride to a full day, valley to valley. Discover the Mérens horse →

A few kilometres away, in the Orlu national reserve, an 8-hectare park is home to around twenty European, Canadian and Arctic wolves — with a viewing tunnel that lets you watch them from just centimetres away. Discover the Maison des Loups →

Ten kilometres from Ax-les-Thermes, the ruins of Château de Lordat tell the story of the last Cathars fleeing after the fall of Montségur — a ten-minute walk up from the ticket office, with the Ariège valley opening out beneath you. Discover Château de Lordat →

Beyond the activities above, the valley’s original draw is still here: Le Bassin des Ladres, Les Bains du Couloubret, and both the traditional 18-day medical cure and shorter 3-6 day wellness breaks. Discover the thermal baths →

A single base makes trying several of these activities in one trip genuinely practical, rather than relocating each day. See Natik Studio →
