From Ansabère to Acherito

A cross-border circular to discover a little-known area (Ibón de Acherito) from a very popular location (Cabanes d'Ansabère from Lescun). Magnificent landscapes, a varied route.

Hike published in Pyrénées Magazine in 1995 (without a map and with little detail on the descent).

Update: According to several hikers' reviews (see the associated forum), it would be preferable to do this route in reverse.

Description of the walk

Access: From Oloron-Sainte-Marie, take the N134 towards Saragosse. After Bedous (diversion), turn right towards Lescun and immediately after the factory, turn left towards the Lhers plateau. After the winding climb, turn right (signposted "Ansabère") and continue to the end (car park).

You can park at the Lamareich car park (960 m). Alternatively, you can drive up to the next car park (Pont Lamary), but you must drive very slowly to avoid damaging your car and to respect the walkers using this track.

(S/E) Follow the dirt track, climbing gently to Pont Lamary (altitude 1175 m).

(1) Cross the stream via the concrete bridge and climb up the rather rough track opposite, towards the Cabanes d'Ansabère. When you leave the forest, you will arrive at a large pasture called Pla d'Ansabère.

(2) The path branches off to the left, crossing the stream. Climb through the undergrowth, still following a rough track. The Cabanes d'Ansabère are above the forest, at an altitude of 1560 metres.

(3) Follow the signs and turn left onto the path to Lac d'Ansabère. The path, now marked in yellow, begins to climb more steeply to reach Lac d'Ansabère (altitude 1859), a superb viewpoint over the Aiguilles d'Ansabère.

(4) Find a fairly well-marked trail behind the lake (south side). This trail initially climbs straight up the slope, then veers westward. This will take you easily to the unnamed border pass at an altitude of 1991 metres.

(5) After admiring the vast panorama, take the path that descends on the Spanish side and soon turns sideways. This crossing leads to a flat passage on a shoulder where you can see the large Ibón de Acherito lake.

(6) Do not descend towards the lake but head along the hillside (general direction: east). Aim for a gap between the Pic du Lac de la Chourique and the Pic de Laraille, named Brecha de Hanas on the Spanish IGN map. You will need to cross some very large boulders, which is not difficult other than needing to watch your step. Once below the gap, find a path that climbs steeply, zigzagging. The last ten metres are very steep: it is a good idea to use your hands at times, as there are excellent handholds.

(7) The breach (altitude 2,035 m) opens onto a slightly less steep slope where the path zigzags downwards in the same way. You must still be careful not to roll stones onto other members of the group.

(8) At an altitude of around 1,850 m, the scree gives way to a grassier area with a few rocks, between which the well-marked path winds its way down. Stay in the valley all the time. The slope gradually becomes gentler and turns to the right (north-east).

(9) At an altitude of 1,580 metres, pass above the Fontaine Bourrégué. Continue eastwards, then cross a stream and turn north (elevation 1,552 metres); the path is well marked. Enter the beech forest after crossing an area of large erratic boulders.

(10) At the edge of the forest (around 1280 m), the path turns sharply to the left. The path then disappears more or less into a vast pasture; continue north to reach Pont Lamary.

(1) From the Pont de Lamar car park, turn right and head for the Lamareich car park (S/E).

Notes

  • Period: May to October.
  • Water and cheese at the Cabanes d'Ansabère.

Warnings:

  1. Beware of the "patous" (guard dogs) that guard the herds: do not approach them, go around them to avoid any problems and respect the work of the farmers.
  2. To find the route on the Spanish side, use a map (IGN or Openstreetmap) with a compass.
  3. Only set off in good weather. The retreat to the Spanish side is not immediate, and the road (at Selva de Oza) is very far from the starting point.
  4. The route above Lake Acherito and on the northern slope of the breach may be covered with snowfields at the beginning of the season (May-June). This can be convenient (fewer scree slopes to cross) but also dangerous. Never attempt to cross a steep snowfield with hard snow: there is a risk of fatal slipping! On the other hand, if the snow is very soft, the snowfield may collapse.
  5. The descent sometimes runs along the edge of the National Park. Please respect the rules: no dogs, no picking flowers, etc.

This route passes through a protected area, which may be subject to special regulations:

Worth a visit

There are many chamois in the border area above Ibón de Acherito.

Pleasant hike, although very busy.
Many shaded areas.
The shepherd at the hut sells cheese and drinks.

Yes, in foggy weather it can be tricky in such rocky areas. Above Lake Acherito there isn't really a path, except for the last few metres before the breach.
In such cases (as in others), using GPS in conjunction with the Visorando app (+ map) is very useful. The Spanish map is available in the app.

The route to Lake Dansabere is clearly visible, but on the Acherito side of the lake, to cross back over to the other side via the gap, the path is much less frequented and sometimes not very visible. Not recommended in foggy weather, but otherwise very pleasant with varied scenery.

The best route is to go to Lake Ansabere, then Lake Acherito, take the path on the left, pass through the Hanas gap, then descend into the Lazergue woods and return to the car park where you started.

Yes, it's a general fact: a route description is rarely valid for following the route in the opposite direction. You would have to walk backwards (and even then)!
The only solution is to rewrite the description for the reverse route.

As suggested by a comment, we did the route in reverse.

Absolutely magnificent! It's rare to find hikes with so many different landscapes in such a short distance.

However, by doing it backwards, I got lost between points 9 and 7 countless times, with lots of paths leading off to the left.

This side of the route is not marked except for a few cairns. It was a nightmare to find the path leading to the breach in the foggy weather. Especially since the slope is steep (almost 45°).

The rest of the route went smoothly. An excellent route, despite my need to improve my sense of direction.

Thank you. The Lazerque clearing is ideal for camping. Higher up, flat spots are rare...

Great hike!
The start is fairly gentle, all the way to the Ansabère huts.
We had a superb view once we reached the pass. We took the time to settle down at Lake Acherito and pitch our tent for the night. Lake Acherito on the Spanish side is really worth the effort. There are very few French people there because it's quite a difficult hike for us to access. On the other hand, it's easy to access from the Spanish side, so there are quite a few visitors on their side.
We decided to get up at 5:30 a.m. and continue on our way to see the sunrise at the top of the pass. The landscape was magnificent, with abundant wildlife and a sea of clouds at the bottom of the valley.

If you want to camp, we recommend crossing the breach and descending into the forest to set up camp. You will be much more peaceful there!

A very beautiful route that is easy to follow.

Indeed, GPS is very useful for finding your way around on the map in these somewhat chaotic terrains. But at least you saw the beautiful Acherito lake...

I didn't have a GPS and I didn't manage it despite the information and map I found on Visorando. But I'm a beginner when it comes to reading maps.
I managed to get to Lake Ibon D'Acherito, but then I couldn't find the right path to reach the pass.
I think that with a better analysis of the route and comments from other hikers, I'll do better next time on this lovely hike or another one.
PS: At the start of the walk, there was a detour because the usual path was closed due to forestry work. The detour is wilder, which I really liked (walk in early June 2024).

A magnificent hike with lots of Izards. The tour of Lake Acherito was a bonus.
Easy to follow the route.
No difficulty for regular hikers.

A superb hike with magnificent scenery. The climb up to the lake is long but gradual, with three quarters of the route on a very good path. It is essential to climb up to the pass for the splendid view. On the Spanish side, there's no point in descending halfway up the slope. Either go to the lake or head for the pass (where there are izards). The passage is a little tricky. The return on the other side of the pass is very steep at the beginning (and rocky) and the path is easy to lose. But it's also a very beautiful route.
As for arriving by car, the track makes it PARISH SPECIFIC TO BRETTAIN to climb to point one (very few bumps, but a little caution is still required, especially at the beginning). We did it on foot following the alarmist comments and saw many normal vehicles passing without difficulty (Ferraris should be avoided, but a Clio is fine).
