Arlet Refuge and Lake Arlet from the Espélunguère car park

There are several routes to Lac d’Arlet and the Arlet Refuge. This is one of the most beautiful: varied scenery with a magnificent viewpoint at an elevation of 1909 metres on the map, followed by the arrival at Col de Lapachouaou. The first half of the hike is steady but fairly strenuous. The rest of the way to the lake follows the contour lines more or less. You’ll have plenty of time to admire the stunning scenery unfolding before you from the slopes of Montagne de Banasse.

Description of the walk

In Oloron-Sainte-Marie, take the Route du Somport. Before the tunnel, and just opposite the road leading up to the pass, turn right onto the small Route des Forges d’Abel. From there, head towards the power station and then take the Route Forestière d’Espélunguère to the car park (altitude 1,350 m).

(S/E) Take the path that branches off to the left of several information boards. It climbs south-west and passes to the right of a waterfall below. The path rejoins the forest track you left at the car park.

(1) Cross the track and take a path opposite, which cuts across three hairpin bends in succession to rejoin the track at around 1,480 m.

(2) Follow it north-east through the forest, emerging at around 1,580 m. Stunning views of the Pic du Midi d’Ossau. Continue to the Col de la Mousquère (1,628 m): views of the Cabane de Grosse.

(3) Continue climbing north-west to reach the hut at 1,630 m.

(4) Go round the hut on the right. The gradient steepens to reach the 1909 m high point: view of the Lapachouaou valley.

(5) The path veers sharply left towards the west and then north-west, running almost flat to the Col de Lapachouaou, 1891 m.

(6) The path continues horizontally along the slope of Montagne de Banasse. Pass above the Cabane de Gourgue Sec and reach the junction with the path coming from Aubise (1,880 m).

(7) Continue along the well-marked path. It begins to climb gently again to reach the area above the lake, then descends to the lakeside at an elevation of 1987 m.

(8) Continue on to reach the refuge (which is due to reopen after renovation work in summer 2023). After a pleasant rest, return via the same route to the Espélunguère car park (S/E).

A pleasant hike that complements the one around Lake Estaens well for those who would like to do these hikes over two days.

I was lucky enough to receive some great advice from the park guides about the patous (mountain dogs):
1- take off your sunglasses so they can see where you are looking and don't feel threatened or stared at;
2- hold your walking sticks in front of you like a shepherd (if they bite, they'll be the ones to get hurt);
3- turn so that they are never behind you;
4- Tell them "go to the herd", which is a term they understand
5- obviously, as with all dogs, don't shout or stare at them.

I tried it out, surrounded by four Patous (I wasn't feeling very confident), and the sticks helped me feel safe, and the "go to the herd" trick worked well.

It rained on the way back (I was doing a round trip), but it was a very nice hike, and I spent some time at the refuge waiting for the rain to ease off.

Very beautiful views, worth doing, even if the lake isn't the most beautiful, because apart from the refuge, you can't see the mountains reflected in it... I liked the passages from valley to valley thanks to the passes. Thanks for the description.

From memory, you can see up to 4-5 huts.

I would advise against driving a low-clearance car to the car park. It is better to park near the upper power station, which is less than a kilometre from the designated car park. A short, steep path allows you to shorten the route.
A very beautiful hike that can be turned into a route via the ‘Espagne’ path near the refuge. Elevation gain of around 1,000 metres and 19 km. I haven’t tried this route myself.

At that time of year, I was blessed with glorious sunshine. There were a few patches of snow to cross without any risk; just make sure you bring gaiters to keep your feet from getting too wet, and something to keep you warm for a good night’s sleep in a bivouac (the winter refuge has five beds, which fill up quickly...).
If you still have some energy left after the 3.5–4-hour climb, don’t hesitate to leave your gear at the Arlet refuge and make a round trip to the Pic d’Aillary (2,215 m – 1 hour round trip) via the Col d’Arlet. A magnificent panoramic view is guaranteed!

A route for amateurs exploring the Pyrenean mountain landscape: the varying altitudes of the vegetation, thriving pastoral life, contrasting landscapes, colours and slopes, and the ever-present peaks.
A magnificent journey.

Hello Hervé ???
The elevation gain shown is 830 m and is correct.
The app often gives incorrect elevation figures when you’re out and about. To correct them, go to ‘Actions’ and click on ‘Recalculate elevations’.

It’s a shame, but the elevation gain given is completely unrealistic. For example, 1,300 m instead of 600 m
