1. The Ayous lakes and the pic du Midi d'Ossau: the jewel of the Ossau valley
Nestled in the Pyrénées-Atlantiques, the Ayous lakes loop constitutes undoubtedly one of the most emblematic hikes of the Pyrenean range. This 14-kilometer route takes you to discover no fewer than five high-altitude lakes, each offering a different reflection of the majestic pic du Midi d'Ossau which peaks at 2,884 meters. The departure is from the Bious-Artigues lake parking, accessible from the village of Laruns.
The route gradually climbs through a pine forest, then opens onto high-altitude pastures where free-roaming horses often graze. You will successively discover lake Roumassot (1,845 m), lake du Miey (1,914 m), lake Gentau (1,947 m) where the Ayous refuge stands, then lakes Bersau (2,083 m) and Castérau (1,943 m). Each body of water offers a unique perspective on the pic du Midi d'Ossau, nicknamed "Jean-Pierre" by locals due to its characteristic two-peak shape.
Practical info: Allow 5 to 6 hours for the complete loop with 650 meters of positive elevation. Level: intermediate. The best period extends from June to October, outside snowy periods.
2. The Beille plateau and Mérens horses in Ariège
A true well-kept secret of Ariège, the Beille plateau is discovered through an accessible hike that immerses you in the heart of an exceptional pastoral landscape. Perched at 1,800 meters altitude, this summer pasture plateau welcomes transhumance herds each summer and especially herds of Mérens horses, these magnificent black equines emblematic of the Ariège Pyrenees.
The Mérens, nicknamed the "black prince of the Pyrenees", lives here in semi-freedom in a setting of rolling meadows bordered by spruce forests. Observing these hardy horses evolving in their natural environment constitutes a magical experience, particularly at sunrise or sunset when the grazing light sublimes the plateau's reliefs. Foals frolic alongside their mothers, while stallions watch over their herds with natural majesty.
Beyond equine encounters, the Beille plateau also offers exceptional panoramas of the surrounding peaks and constitutes an ideal starting point for more athletic hikes to the border ridges. In winter, the site transforms into a Nordic ski resort, but it is indeed in summer that the magic operates fully.
Practical info: Road access to the plateau from Les Cabannes. Several marked trails allow exploring the summer pastures. Level: easy to medium depending on the chosen route.
3. The Gavarnie cirque: a grandiose natural amphitheater
Listed as UNESCO World Heritage, the Gavarnie cirque remains an unmissable destination for any hiker traveling through the Hautes-Pyrénées. While the site attracts numerous visitors, it nevertheless maintains a majestic and wild character that commands admiration. The limestone cliffs rise 1,500 meters high, forming a spectacular natural amphitheater at whose foot tumbles the Grande Cascade, 427 meters high.
The classic trail from the village of Gavarnie represents a family-friendly 8-kilometer round trip with only 200 meters of elevation gain. However, for a more secret and immersive experience, favor the route via the Espugues ledge which offers vertiginous perspectives of the cirque. This more athletic variant allows admiring the waterfall from a unique angle and encountering far fewer people.
For the more adventurous, the ascent to the Roland breach, this legendary notch separating France from Spain at 2,807 meters altitude, constitutes an ambitious but unforgettable objective. The view from this mythical pass over both sides of the Pyrenees amply rewards the efforts made.
Practical info: Village of Gavarnie accessible from Luz-Saint-Sauveur. Classic route: 3h round trip, easy level. Roland breach: 8h round trip, difficult level, 1,400 m elevation gain.
4. Lake Estaing: secret pearl of the Hautes-Pyrénées
Less known than its neighbors but equally magnificent, lake Estaing nestles at 1,163 meters altitude in a setting of wooded mountains. This natural dam lake offers a peaceful and wild setting, ideal for a family hike or a first discovery of mountain hiking. Accessible by car from the village of Estaing, the lake constitutes an excellent starting point for more advanced excursions.
The lake loop is completed in one hour on an easy trail that winds between forest and shore. But seasoned hikers can push to lake Plaa de Prat (1h30 additional, 495 m elevation gain) or even to the Ilhéou refuge, nestled at 1,985 meters in a sumptuous glacial cirque. These extensions allow immersion in preserved high mountain landscapes where wildlife (marmots, chamois, raptors) reigns supreme.
In summer, shepherds lead their flocks to these summer pastures and it is not uncommon to encounter sheep, cows and horses grazing peacefully along streams. The pastoral atmosphere emanating from these encounters reinforces the feeling of being outside time, in a world where man and nature still coexist harmoniously.
Practical info: Road access to the lake from the village of Estaing. Lake loop: 1h, very easy level. Extension to lake Plaa de Prat: medium level.
5. The Aure valley and Néouvielle lakes: biodiversity sanctuary
The Néouvielle nature reserve, accessible from Saint-Lary-Soulan in the Aure valley, shelters no fewer than 70 lakes and tarns scattered in a breathtaking mineral setting. This biodiversity sanctuary protected since 1936 constitutes one of France's oldest nature reserves. Century-old mountain pines neighbor rhododendrons and blueberries here, creating a unique ecosystem.
Among the secret hikes in the Pyrenees, the Aumar and Aubert lakes circuit represents an accessible classic that reveals all the beauty of this granite massif. The trail winds between rocky chaos and alpine meadows, offering new panoramas of the turquoise-watered lakes at each turn. The most courageous will push to Cap de Long lake, a majestic body of water dominated by the Néouvielle peak (3,091 m).
The site's ornithological richness also makes it a paradise for bird watchers: bearded vulture, golden eagle, rock ptarmigan and yellow-billed chough frequent these heights. With luck and patience, you will also spot marmots, chamois or even a capercaillie in the undergrowth.
Practical info: Lakes road open from late May to early November (check before). Aumar-Aubert circuit: 2h30, easy level. Extension to Cap de Long: 4 to 5h, medium level.
6. Kakuetta gorges and pottoks of the Basque Country
Radical change of atmosphere with the Kakuetta gorges, a spectacular canyon carved 80 million years ago in the limestone of Haute-Soule. This easy but striking hike takes you into a mineral and aquatic universe where the torrent thunders between vertiginous walls 200 to 350 meters high. The lush vegetation, almost tropical, clinging to the cliffs creates a mysterious atmosphere.
Important note: The Kakuetta gorges are currently closed for safety and modernization works. Reopening is planned for 2026-2027. Meanwhile, hikes on the heights of the Basque Country allow admiring other wonders.
The inland Basque Country indeed offers magnificent hikes where you will encounter the famous pottoks, these small wild horses emblematic of the region. On the massifs of la Rhune, Baïgura, Artzamendi or Ursuya, these hardy ponies live in semi-freedom, perpetuating a millennial tradition. About 1.30 meters high, generally black or bay-colored, these stocky equines graze peacefully on mountain slopes, indifferent to hikers passing at respectful distance.
The ascent of mount Baïgura (897 m) from the eponymous leisure base constitutes a beautiful 3 to 4-hour loop offering 360° panoramas of the Basque Pyrenees and Atlantic Ocean. The meadows covered with golden ferns in autumn and herds of pottoks galloping in the distance compose unforgettable tableaux.
Practical info: Mount Baïgura accessible from Macaye. Several possible routes, from 2h to 4h depending on the chosen loop. Level: medium. Observe pottoks from distance without disturbing them.
7. The Aspe valley and the Mâture path: historical hike
Among the secret hikes in the Pyrenees, the Mâture path in the Aspe valley deserves special mention for its exceptional historical character. This spectacular trail, carved into the cliff face in the 18th century, served to transport masts for the Royal Navy from valley forests to Béarn. Only 1.50 meters wide in places, it overlooks the Aspe torrent by several hundred meters.
The hike, accessible from Etsaut, first follows the torrent before beginning a gradual climb through beech forest. Then comes the gripping moment when the trail engages on the vertiginous ledge. Sensations are guaranteed, even if cables secure the most exposed passages. Once the Mâture path is traveled, you can push to Arras pass (1,614 m) which offers a plunging view over the valley.
The Aspe valley, the wildest of the three Béarn valleys, conceals other treasures like the Lescun cirque, the Ansabère huts or even lake Montagnon, a renowned bivouac spot. This authentic valley, preserved from mass tourism, allows total immersion in the Pyrenean mountains.
Practical info: Departure from Etsaut. Mâture path round trip: 3h30, 400 m elevation gain. Level: medium but vertiginous passages (not recommended for people prone to vertigo). Extension to Arras pass: 6h, athletic level.
