Description of the walk

Park your vehicle in the Pont d'Espagne car park.

(S/E) Continue to the Pont d'Espagne.

(1) Cross the bridge and follow the right bank of the Gave de Cauterets. Shortly after the Gaube chairlift departure station, cross the bridge and turn right. Stay on the right bank for 1 km. The path is still fairly flat and allows you to warm up a little. The rest of the route is much more difficult.

(2) Cross the bridge and pass the Refuge du Clot chalet.

(3) Turn left and follow the Plateau du Clot to the Pont du Cayan bridge.

(4) At the Pont du Cayan bridge, turn right and follow a path towards the Lacs de l'Embarrat, where the slope quickly becomes steeper. This is the most difficult part of the hike, especially if the sun is beating down. After a little over 200 m of elevation gain, you will emerge from the forest and begin to enjoy the view.

(5) You will then reach the Lacs de l'Embarrat (two lakes at 2,078 m and 2,139 m above sea level), leaving a path on your right.
Continue climbing, following the trail to Lac du Pourtet, 300 m higher up at an altitude of 2,420 m. The landscape then becomes very rocky.

(6) From Lac du Pourtet, the trail leads to Lac de Nère.

(7) At 2,309 m, in a maze of rocks of various sizes, after a small pass just above Lac du Pourtet. From here, enjoy the view, especially towards Vignemale.

Then begin the descent. Between the lake and the left bank of various mountain streams, you will pass three trails on your right and the Wallon-Marcadau refuge.

(8) The descent is almost entirely outside the forest.

Reach the Pont d'Espagne by following the Gave du Marcadau, first on its left bank, then on its right bank via the Pont d'Estalounqué.

(9). Continue to the Pont du Cayan.

(4). After the Pont du Cayan bridge, which you will leave on your left, the path becomes passable by car. Continue along this path.

(2) Continue straight ahead and, taking the same route as on the way there, reach the car park (S/E).

Notes

Remember to bring plenty of water and provisions. The climb, when the sun is strong, makes you sweat a lot.

Make sure you wear suitable walking shoes and bring something to cover up with in case of rain. Storms can develop quickly even when the sky is blue.

You will have to pay a fee if you park your car at Pont d'Espagne.

The length of the climb from the Cayan bridge to Lake Nère does indeed require a good deal of energy and perseverance. The beauty of the surroundings keeps us going.
In order to savour this walk by allowing myself breaks, as I loved the diversity of the landscapes on this hike so much, I preferred to sleep at the Wallon refuge rather than "gallop" to complete the circular in a single day.

Beautiful hike with high-altitude lakes, climb up to the lakes and pass by the Wallon refuge, which is steeper but you can rest on the way back

departure at 7:30 a.m., few people at that time, the times indicated are correct and the route is well marked. Magnificent scenery, arrived at the Wallon refuge with lots of people but very well managed by the entire refuge team.

Superb hike with lots of variety (river, meadows, forest, rocks, lakes, viewpoints 🤩). Completed in 8.5 hours with photo breaks at a leisurely pace. Saw few people until the Walloon refuge (departure at 7 a.m., at sunrise).

A superb hike that allows you to discover three magnificent lakes! We did the hike in the opposite direction. However, this hike is very busy in early August, so it's best to set off early in the morning!

A magnificent hike that takes you to three lakes and a mountain refuge.
We were unsure of the route once or twice, but the GPS was very helpful. We found that the directions before the Lac de l'Embarras were a little vague (a couple more signs would have been welcome).
Otherwise, absolutely brilliant!

Superb hike completed on 20 October 2024 with snow on the higher ground but no difficulties. Magnificent landscapes, especially around the series of lakes. Thank you for this route.

A beautiful hike, quite long; the lakes that follow one after another are all different, and the valley you cross after the refuge is relaxing. Best done early in the morning.

Significant difference between the length given by Visorando (19.45 km) and that given by the SUNTOO app (24.49 km)
The same applies to the elevation profile: Visorando 970 m and SUNTOO 1,154 m

A challenging hike with nearly 800 metres of elevation gain over a distance of 4 kilometres, often on scree. A stunning, rocky landscape around the lakes. A tricky, fast descent to the Walloon refuge, which is a welcome relief before returning to the Pont d'Espagne via the magnificent Marcadau Valley.
Recommended for sporty types!

Thank you for this summer version of the tour.

We did the winter version yesterday, complete with a climb up a peak, the Soum de Bassia (2,758 m). I've already sent you a report on that!

This was my second time there, both times in winter, and the lack of snow was very noticeable, but all the lakes were frozen!

Thanks
Have a good week

Hike completed on 23/10/2023

The most beautiful hike I have ever done, encounter with a chamois and a mouflon at dawn (around 9 a.m.)

the description is accurate but sometimes a little vague, particularly after Lac d'Embarrat

With a bit of luck, there was snow between Lac du Pourtet and Lac Nere, which made it a magical moment

it is possible to extend the hike as there are 2-3 lakes nearby

Quite a long hike (8 hours of walking) completed at the end of the season in beautiful weather and in the opposite direction (schedule)
Easy climb up the glacial valley to the Wallon-Marcadau refuge (for a coffee!)
Beautiful climb to the lakes (Lac Nère, Lac du Pourtet).
A rocky atmosphere at Lac du Pourtet and a beautiful moment. The descent to the Embarrat lakes is superb.
On the way down just after the upper Embarrat lake, keep to the right, leaving the path that follows the contour lines towards Ilhéou on your left.
From the lower Embarrat lake, there is a beautiful descent through the forest to the valley for an easy return to Pont d'Espagne.
