Description of the walk

(S/E) After the cable car station (paid parking), take the road that climbs towards the Plateau du Clot.

(1) After the first hairpin bend and just before the bridge, take the path that climbs left into the forest (GR®10markings) towards Lac de Gaube. The path is quite steep, but the slope eases off afterwards.

(2) Pass Lac des Huats and continue to Lac de Gaube, then exit the forest.
Turn right (or left for refreshments at the Hôtellerie du Lac!), cross the Gave de Gaube.

(3) Walk along the left bank of the lake.
At the southern end of the lake, follow the path, still on the left bank of the river. The path climbs rapidly along the river. Further on, cross it via a footbridge and leave the Cabane du Pinet hut on your left.

(4). Reach a plateau. Cross the river again and climb a steep slope near the Esplumouse waterfall.

(5) At the waterfall, there is another landing where you cross a tributary of the Gave de Gaube. Cross another ledge on the left bank of the river.

(6) You will then reach the Refuge des Oulettes de Gaube at the foot of the Vignemale (see practical information).
The view of the Vignemale is magnificent!
Leave theGR®10, which heads left towards the Araillé lakes, and take the path on the right that crosses the bivouac area and climbs up to the Col des Mulets: a 500 m climb, very steep, over scree, but well marked.

(7) The Col des Mulets marks the border between France and Spain. Turn right onto a path that runs along the edge of the Aiguilles du Chabarrou in an arid landscape. Izards may be present.
You will then reach the Col d'Arratille (back in France!).

(8) From the pass, you can see the path that descends into the Arratille valley (northbound) and the many lakes that dot the valley.

Walk along the first lake of the Col d'Arratille, then follow the Gave d'Arratille river on a fairly steep descent through the rocks. Cross the river several times before reaching a flat area at Lac d'Arratille.

(9) Go around the lake on the left bank (you can also swim here, but the water is cold!). After crossing the Gave d'Arratille, the slope is still hard on the knees. You are now on the right bank of the river, and the vegetation is becoming increasingly abundant with the appearance of mountain pines: the setting is splendid and you may even spot a few marmots on the trail itself.
The slope eases off a little before the umpteenth crossing of the Gave d'Arratille, then the Gave des Batans. You will then reach a junction.

(10): To the left, you can head towards the Refuge Wallon (about 200 m away - see practical information). Turn right towards Pont d'Espagne, which is a 'motorway'...
Cross the Gave de Marcadau at the Pont d'Estalounqué.

(11) Follow the path that leads away from the river into the forest.
The path then becomes a wider track and rejoins the river a little further down at the Plateau de Cayan (altitude 1,630 m).
From there, there are two options:
- cross the river at Pont de Cayan and follow the left bank of the river to the Chalet-Refuge du Clot.
- stay on the track on the right bank, following these directions: stay on the track, which is paved further down, and crosses the two branches of the river at the Chalet-Refuge du Clot.

(12). Go around the Pont d'Espagne restaurant, cross the river at Pont d'Espagne and then descend to the cable car station (S/E).

Three-day hike on 7, 8 and 9 August. Day 1: 8 km in the afternoon, Pont d'Espagne GR 10 = tough from the start and very crowded at this time of year... the scenery is fantastic ==> Oulettes refuge Bivouac: magnificent Vignemale. Day 2: 8 km all day (tough, very tough at the start because from the plateau to the Col des Mulets it's a crazy climb (I'm 58, athletic, but a 14-year-old kid is killing it!!! ) From the Col des Mulets to the Col d'Arantille it's okay, but you have to stay alert as there are two fairly tricky sections. Then THE Descent... it's tough but as you descend it gets more and more beautiful!!! Don't miss the Wallon Marcadau refuge, which is exceptionally beautiful. We camped there = Splendid. And on the third day, we only walked in the morning, arriving at Pont d'Espagne in less than 3 hours, 8 km (easy descent)! Magnificent landscapes all along the route with forests, plateaus, mountains and lakes. We therefore recommend this hike, but not for beginners who are unfit and poorly equipped (we came across some and I felt sorry for them...)

A two-day hike with a bivouac near the Wallon refuge! This makes for a long first day (18.3 km rather than 16.24 km as indicated in the description). The second day was more relaxed with the descent to the Pont d'Espagne (8 km OK)! Lots of people at Lake Gaube, a little less at the Oulettes refuge and almost no one at the Col des Mulets (a very tough climb for our beginner's legs!!!). The descent to Lake Arratille was tough on our ankles and knees (especially with fatigue). Magnificent scenery throughout the route with forests, plateaus, mountains and lakes. We therefore recommend this hike (take a light bag if you want to do it in one day).

A two-day hike with a bivouac at Lake Arratille. We are fairly novice hikers.
Magnificent and varied views! Two days in the mountains, from the forest in the lower part to the Col Minéral at 2,590 metres, passing through the green valley and its waterfalls.
However, don't underestimate the difficulty of the route. The climb to the Col des Mulets and the section that follows towards Lake Artille are demanding on the legs and ankles. It took a lot of effort! The weather was mild in August (sunny and not too hot), but the route can be difficult in harsher conditions.
So, check the weather forecast carefully, pack as light as possible and make sure your legs are well prepared.

One small point to note: on the section after Col des Mulets leading to Col d'Arratille, the path to follow is actually higher than the route indicated in the app.
Another point to note is that we did not have any mobile phone reception during the entire hike.

Enjoy your hike!

Circuit completed in 9 hours... including breaks! But you can't slack off!
Climb up to Les Oulettes without overexerting yourself, because after that it gets tough!
Lunch break at Col du Mulet.
If you're in slightly above-average physical condition, you'll be fine, but if you have any doubts about your abilities, do it over two days.
Thanks to the creator of this circuit, we had a great time!

Superb hike. The valleys you cross are all different, making for a varied and magnificent route!
The climb to Col des Mulets is steep and tough on the legs! But there are no technical difficulties, it's still just a hike.
A truly superb route over two days. Magical.

hello,
The trail is very well marked from start to finish
A magnificent loop with very varied landscapes
The most difficult part is the climb up to the Col des Mulets (quite strenuous) and the descent into the valley (hard on the knees).
But what can I say about the Marcadou Valley other than that it's a truly magnificent place? I'm really in love with this place.
Having seen walkers in Stan Smith trainers and trainers, and as others have said here but apparently not enough, I'll say it too!!! You mustn't take a hike lightly and think you're stronger than others.
Wear a good pair of high-top shoes and be equipped with the minimum necessary, especially in such rocky areas.

hiking is a walk, not a race

happy hiking, everyone!

A magnificent loop completed in 9½ hours in the opposite direction. The length, elevation gain and uneven terrain would make it difficult to classify if done in a single day as suggested in this guide. No technical difficulties in the absence of snow and fog. From the Marcadau refuge to the lake, follow the cairn-marked trails.

Great hike, but bring walking sticks for the climb up the mule tracks. I struggled a bit on the rocky ground, but the place is magical and well worth the effort. The campsite at Lake Aratille was fantastic. I recommend this hike if you have good walking boots and strong calves

A superb hike that took our breath away!
It took place over two days and two nights, starting at 7 p.m. from Pont d'Espagne, with a bivouac at Lake Gaube, then another bivouac at Lake Aratille for the second night, before descending back to Pont d'Espagne via the magnificent Marcadau Valley.
Be sure to bring high-top shoes, as most of the hike is on rocky ground.

A two-day hike with camping. Stunning scenery with wildlife as an added bonus (marmots and chamois). A bit crowded from Pont d'Espagne to Lake Gaube, but after that it's more peaceful. The climb to Col des Mulets is particularly challenging, but what a spot. The path leading to the Col d'Aratille is clearly visible, but you need to be extra careful for a few metres in places. The descent to Lake Aratille is easy on the joints
. Please note that the Wallon refuge is undergoing (major) renovation work and will therefore be closed until the end of 2021 (to be confirmed)
A superb hike, nothing but good things to say

A two-day hike with a bivouac at Lake Arratille. The scenery is magnificent, and splitting the hike into two makes it more accessible. For parking, you can park at La Raillère or even at Cauterets (adds 7 km), which avoids the paid parking at Pont d'Espagne.

Otherwise, the description is very accurate, and the climb to the Col des Mulets is indeed quite steep!
