Hiking and wildlife watching in the Pyrenees

June to September

4 days| 3 nights

Eco-score 4/5

What you will experience

Explore the wild high valleys of Cauterets, between Lake Ilhéou, the Marcadau plateau and Lake Gaube, dominated by the Vignemale, in the heart of the Pyrenees National Park.

Hike to the rhythm of the fauna: marmots near the burrows, chamois on the grassy slopes, Iberian ibex on the granite bars and dipper along the torrent.

Set off with a mountain leader who is an expert animal spotter, teaching you how to read a ledge, spot a silhouette with binoculars and understand the behaviour of species.

Sleep every night in a comfortable mountain hut, like the Ilhéou hut nestling on the edge of its high-altitude lake, in the heart of a wild setting of peaks, high-altitude meadows and granite plateaux.

We'll meet at 9am at Lourdes station to meet the group and brief the guide, before transferring to the Cauterets massif where we'll begin our hike above Cauterets.

On this first day, we'll head up the Ilhéou valley, a pastoral valley dotted with mountain pastures and clearings shaped by the summer grazing, with valleys and grassy slopes ideal for observation. We'll keep an eye out for marmots, often visible near their burrows, and for the mountain birds of prey that regularly fly over the area.

The ascent follows a well-marked path and leads to a high altitude lake, nestled in a mineral and open environment. Depending on the weather and the shape of the group, a short exploration option is possible.

Settle in and spend the night at the Ilhéou Mountain hut, on the edge of the lake: quiet time for dinner, collective feedback and preparation for the next stage of the expedition.

After breakfast at the Mountain hut d'Ilhéou, we continue on towards the Col de la Haugade, a high-level pass that opens the door to the Marcadau valley. The ascent takes us across grassy slopes and sunny ridges, an area ideal for spotting chamois.

Higher up, the environment becomes mineral and typically granite, with rocky bars frequented by Iberian ibex, which can be seen through binoculars brought along by your guide.

Switching to the Marcadau side, we walk alongside a glacial lake that bears witness to our geological history, before descending along a comfortable path lined with hooked pines.

The route leads to the Mountain hut where we'll spend our second night, set on a vast high plateau renowned for its wealth of wildlife.

We'll spend the night here, in the midst of an unspoilt natural setting where the evening light magnifies the surrounding peaks.

On this, our third day's hike, we gradually make our way up to a wild valley, untouched by the main hiking routes. We adjust our pace and take breaks to observe them without disturbing them.

As we continue to climb, we reach a more mineral environment, ideal for observing mountain wildlife. Chamois may appear on the grassy slopes or rocky ledges. And if we're lucky, we might even catch a glimpse of the more massive silhouette of the ibex, discreet but very present in this sector.

We descend to the bottom of the Marcadau valley, then the path follows the clear waters of the torrent, between forests of hooked pine, wetlands and open clearings. We arrive at our Mountain hut for this hike, where we spend our last night in a peaceful setting at the foot of the great summits.

  KM covered
After breakfast at the Mountain hut, we head for the mythical Gaube valley along a shady path through a mountain forest of fir and beech trees, punctuated by clearings and a cool atmosphere at the start of the day. The path takes us to the edge of the turquoise waters of Lac de Gaube, dominated by the high peaks: pause at the water's edge to enjoy the site and try your hand at some nature watching.

We then descend towards the Pont d'Espagne, the gateway to the high valleys where waterfalls and torrents gather. We continue along the sentier des Cascades towards Cauterets, skirting the torrent between waterfalls and forest cover: this is a good area to spot the dipper: a bird that frequents these tumultuous waters.

As the day progresses, we return to Cauterets, then take a transfer to Lourdes station for the return journey and the end of our stay.

Story time

Hadrien

Mountain leader (AMM)

French

English

I discovered the mountains at the age of thirteen, when my parents moved to the Hautes-Alpes. It was a real turning point. A dream was born: to help people discover the mountains while preserving them. I fulfilled that cherished dream by qualifying as a mountain leader. Based in the Hautes-Pyrénées since 2016, I share unique moments in the heart of nature. Through photography, I raise awareness of the fragility of our world. My work allows me to portray the mountains in their most noble forms.

Absolument ravie d’être passée par Wildhartt pour ma première expérience de trek/bivouak ! Notre guide Thomas était top, l’organisation parfaite (matériel, repas, logistique) La création du groupe Whatsapp en amont du départ est un vrai + Hâte de réserver ma prochaine aventure !

Christophe R.

Nous avons participé cet été à cette randonnée itinérante de 5 jours avec des ânes en famille, avec nos deux enfants de 8 et 11 ans, et nous en gardons un très beau souvenir. Un grand merci à notre accompagnateur, Romain, qui a parfaitement géré le séjour du début à la fin, y compris lors des moments plus compliqués. Il est très présent et prend en charge une grande partie des aspects pratiques, ce qui est particulièrement appréciable. Il faut cependant garder à l'esprit qu'il reste tout de même un certain nombre de choses à gérer en tant que participant, notamment lorsqu'on voyage avec des enfants. Le matériel fourni pour les ânes était parfaitement adapté et nous a permis de profiter pleinement de l'expérience. Quant au parcours, il était tout simplement magnifique, avec des paysages variés et superbes. Nous avons particulièrement apprécié le premier bivouac, qui se trouvait dans un cadre splendide, ainsi que la nuit en auberge dont le confort a été très apprécié après deux étapes fatigantes. Concernant les points plus mitigés, nous avons trouvé que le début du parcours était sensiblement plus difficile et technique que ce à quoi nous nous attendions au regard du niveau annoncé pour le séjour. La conduite des ânes demande un temps d'adaptation, et la combinaison de cette découverte avec des étapes de randonnée déjà exigeantes a rendu les deux premiers jours assez sportifs. Heureusement, Romain a su s'adapter à la situation en modifiant intelligemment l'itinéraire afin d'alléger la troisième journée. Cette adaptation nous a permis de récupérer et de profiter pleinement de la suite du séjour. Malgré cette réserve sur le niveau de difficulté du début du parcours, nous recommandons cette expérience pour la qualité de l'encadrement, la beauté des paysages et l'originalité de l'aventure avec les ânes.

Laetitia L.

Une randonnée magnifique, dépaysante, avec des paysages variés à couper le souffle. Grâce à Raphaël, nous avons pu voyager autant dans cet espace magnifique que dans le temps, grâce à ses explications sur la géologie de cet environnement.

Serge D.

Partis en rando-ânes en groupe réduit, nous avons pu bénéficier d’un guide exceptionnel qui par son implication, ses connaissances du milieu naturel et son expérience a rendu ce séjour de 5 jours dans les Cévennes inoubliable.

Frequently asked questions

Are the dormitories mixed or separate?

Mountain huts generally accommodate participants in mixed dormitories. There is no systematic separation by gender, but the atmosphere is respectful and adapted to the group dynamic. If someone has a particular need (privacy, difficulty sleeping in a group), they can let us know in advance.

How comfortable is the accommodation?

The comfort is simple but warm. The Mountain huts are heated, have sanitary facilities (toilets, hot showers) and offer quality hot meals. They are not hotels, but authentic places where people sleep in dormitories, share meals and enjoy a collective experience in an unspoilt mountain setting.

Are instalment payment options available?

Yes, that's right! At checkout, you can choose the Alma option to pay for your booking in 2x, 3x or 4x. All you have to do is select Alma at checkout and follow the instructions. It's simple, fast and secure.

Can I privatise this expedition for my group?

Yes, all our expeditions can be privatised for a group already formed, on the dates of your choice.

To make your request, go to the expedition that interests you and click on "Privatise the expedition". We'll take care of the rest!

What kind of people usually join Wildhartt expeditions ?

You don’t need to be a top athlete or adventure expert to feel at home. Most Wildhartt participants are between 25 and 60 years old, with a balanced mix of women and men.

Many join solo or in small groups of two or three. They often live in cities and are looking for a meaningful break — some time to reconnect with nature, slow down, and enjoy something real.

They usually have a regular movement practice (hiking, running, yoga...), but not with a competitive mindset. They’re in good shape, but don’t necessarily have technical skills. What brings them together is a shared desire to disconnect, observe, learn, and experience nature in a more grounded, accessible way.

If that speaks to you, you'll feel right at home. The group spirit is kind and open, and the pace adapts to everyone.

What happens if the weather is bad?

At Wildhartt, nature is our playground, rain or shine. Rain, snow or wind: our guides adapt the itinerary, activities and accommodation to guarantee you the best possible experience.
Unless safety is at stake (storm, avalanche, flood...).

In this exceptional case, we can cancel an expedition, at least one week before departure.
If this happens:
→ You can postpone your adventure at no cost,
→ Or receive a full refund.

What does the price of a Wildhartt adventure include?

At Wildhartt, transparency is essential. The price of your expedition reflects a clear breakdown of costs:

30% for our guides, the mainstays of every adventure.
35% for accommodation and meals, essential for your comfort.
10% for equipment and transport, to guarantee safety and fluidity.
24% for organisation and logistics, from first contact to the end of the expedition.
1% for the rewilding of Europe, a concrete commitment to give back to nature what it gives us.

Our priority: to offer you a quality experience, with complete clarity.
