Gazost walks

Near Lourdes, and dominated by the Pic du Montaigu (2,339 m), the Castelloubon offers a variety of landscapes that can be explored via nine hiking routes of varying lengths. This circular route, starting from Juncalas, follows sections of these trails to explore the eastern part of this High Pyrenees region, featuring forests, pastures and ridges. You can thus admire the high mountain range, the foothills and the plain. It takes you up the Soum de Trées and the Tuquet de Lhési, and also allows you to visit the villages of Gazost, Ourdon, Lias and Ousté.

This ridge hike offers views over a large part of the central Pyrenees. It should only be attempted when there is no thick, unstable snow. The return via the village of Ourdon requires a good sense of direction.

A family walk at the bottom of the green Gazost valley. Discover the history of the sulphurous springs that flow in a damp valley and now feed the thermal baths in the neighbouring valley.

This summit offers a beautiful view of Pic du Montaigu, a prominent peak in the Pyrenees range overlooking the Bigorre Valley.

This is a physically demanding hike, reserved for experienced hikers or trail runners. The elevation gain is very significant over a relatively short distance. It is advisable to bring plenty of water and protection from the sun, as a significant part of the route is exposed. Protection from wind and rain is also strongly recommended.

A beautiful, easy circular path near the small village of Gez-ez-Angles, located a few kilometres from Lourdes.

A magnificent, challenging hike along the ridges at 2,000 m facing the Pic du Midi de Bigorre. Although off the marked trails, it is quite busy in summer. In winter, it is completely off the beaten track for hikers, particularly in the final section (see note in Practical Information below). In winter, as in summer, save this route for a perfectly clear, sunny day, as the views are remarkable and you won’t regret the effort.

This circular walk takes you to four magnificent high-altitude lakes nestled in the heart of the Hautes-Pyrénées: the lakes of Isaby, Plagnous, Ourrec and Bassias (or Couey Seque). The route alternates between mountain paths, mountain pastures and panoramic views of the surrounding peaks. Suitable for walkers accustomed to hiking in mountainous terrain, this route offers an immersion in an unspoilt environment featuring a succession of lakeside scenery, pastoral areas and remarkable viewpoints. A lovely outing to enjoy the diversity of the Pyrenean landscapes and discover several lakes in a single day, or with the option of camping at Lac de Bassias.

Lac dets Plagnous is a tiny lake above Lac d'Isaby. A little more difficult to access than the latter, it is neglected by hikers. However, it is very pleasant and makes you want to stay on its banks for a while.

This is an easy, short hike, ideal for young children. The lake, nestled in lush greenery and surrounded by mountains, is truly magnificent. Calm and peaceful, it makes you want to stay there for a long time.

Montaigu is a beautiful peak in the Hautes-Pyrénées, facing the Pic du Midi de Bigorre and set back far enough from the main border range to offer a beautiful 360° view.

Do not attempt this hike in wet weather. ⚠️ User comment dated 8 March 2026 => There appears to be a serious access issue at the start due to the poor condition of the track.

A classic family walk. A stunning view from the summit, from where, in good weather, you can see the Vignemale, the Pic du Midi de Bigorre, the Ardiden, etc. There are also lovely views towards Lourdes, Tarbes and Pau all along the ascent. The first section is through a well-shaded forest, whilst the second is more exposed. Bring a cap and water in summer. It is a shame, however, that the summit has been left to fall into disrepair, as the promontory is no longer accessible, nor is its orientation table.

A very pretty route with a long ridge walk. This hike allows you to discover some very large summer pastures, some of which are still in use. In the background: the Pic de Midi de Bigorre, the Montaigu and the Mongie valley. Do not attempt this ridge hike in foggy or heavy rain.

This hike is not technically difficult but goes beyond the scope of a "Sunday stroll". Its appeal lies in reaching the pastoral summer pastures above the magnificent Batsurguère valley, at the gateway to Lourdes, and taking a break in a perfectly maintained refuge hut. To the west, you can see the Aguée valley, towards the Col d'Espadres. The place is quiet and superb. With a bit of luck, you will be in the company of horses roaming free on the grassy slopes of the pass.

A beautiful hike that leads to Lake Isaby via the ruins of Saint-Orens Abbey and the Isaby Valley. A pleasant trail, sometimes steep, mostly in the forest before coming out onto the lake and the surrounding peaks (Soum and Pic de Léviste, Soum Arrouy, Soum de Lascours).

Here is another way to reach Lac d’Isaby from Ortiac. Along the way, you will visit the ruins of Saint-Orens Abbey and the Paspich and Pradets waterfalls before reaching Lac d’Isaby and climbing up to the Cabane Picourlet.

In the footsteps of Georges Buisan, born in 1924 in Montréjeau (Haute-Garonne) and resident in Tarbes, he spent his childhood in Bigorre. His interest in the mountains led him to spend several years researching shepherds' huts. Georges Buisan has since passed away, but he leaves behind him, with this Courtaou de la Lit, which he restored over a period of thirty years, an original legacy and a powerful message.
