Ibón de Acherito from the Lamareich bridge car park

This is a long hike with a steady climb, taking you to some beautiful huts, with a water source, a lake in France and a lake in Spain. The elevation gain is significant, exceeding 1,200 metres.
The hike starts at the Lamareich car park next to La Borde de Trésarricq.
This is a difficult hike due to its length and the sense of direction required.

Description of the walk

Access: From Oloron-Sainte-Marie, take the Aspe Valley (N134 - E7) towards Somport. Pass Bedous, leave Accous on your left and continue. Turn right onto the D239 (altitude 489 m) via the Lescun bridge over the Ansabère stream. Climb towards Lescun.
Turn left at the entrance to the village and follow the signs for "Ansabère". Continue along the Chemin de l'Iset to the car park.

(S/E) Lamareich car park (970m). Fork (signpost). Turn left, heading south on a wide track in good condition. There are few yellow markings. Pass the altitude 988m. Climb this track through the forest, which runs a good distance along the right bank of the Gave d'Ansabère. Cross a cattle grid.

(1) Arrive at the end of this wide track, altitude 1175m (another parking area). Cross the river via the Lamary concrete bridge. Continue climbing, on the left bank of the Gave d'Ansabère, along a narrow, stony track in poor condition. Leave the track that climbs to the right and continue along the narrow track. Leave the forest. Arrive at a very large flat summer pasture area.

(2) Ford the Pédain stream (altitude 1363m). Continue on flat ground. Pick up the yellow markings, re-enter the forest and climb up a well-marked path on the left bank of the Gave d'Ansabère. You will reach a fork.

(3) Continue straight ahead. Leave a grassy track on your right that climbs to the Cabane de Pédain.

(4) Cabanes d'Ansabère (1567m). Drinking water point. At this point, there are two beautiful huts and shelters.
Pass between the two huts. There is a sign on the smaller of the two huts (with solar panels). Head towards Lac d'Ansabère. The path, facing south, climbs up the mountainside. Follow the yellow markings. The path is very well marked, but the IGN map is not accurate. Pass the altitude 1754m and arrive at the lake.

(5) Lake Ansabère, altitude 1859m. Leave the lake on your left. A well-marked path climbs due south. The path is steep but safe, climbing towards the unseen pass. Pass the altitude of 1935m, where the path turns due west. At around 1980m, the path levels out and the pass comes into view.

(6) Pass (altitude 1,985 m). On the right, a small peak (2,010 m) offers views of the French (Aiguilles d'Ansabère) and Spanish mountain landscapes. Head left. Caution: no more markings.
Descend southwards for 50m, following a few cairns, through the summer pastures. When you reach a wet area, turn left and head south-east along a path on the mountainside. This path is very well marked, remains flat and then heads south. Go around a ridge and you will arrive above the Ibon de Acherito

(7). This is a beautiful spot for a well-deserved break.
Return via the same path to the car park (S/E).

Notes

Water source at the Ansabère huts.
This is a mountainous area. Your car is not far away. However, as is always the case, you will need:
rain gear, water, snacks, route map, description, map, GPS, camera, very good hiking boots and possibly a walking stick.

If in doubt or in bad weather, know when to turn back.

__Warning:
Be careful of the Pyrenean mountain dogs that guard the flocks: avoiding them is the best way to prevent problems.

A very beautiful hike and an easy route to follow. Thank you to the trailblazer.
The view is magnificent at the highest point overlooking Lake Acherito.
Quite a difficult hike, but if you take it at a hiker's pace and take a few breaks, there's no particular problem.

Hike made partially voluntarily to Lake Ansabé (or Ansabère?) (13.6 km in 6 hours and 5 minutes, with a 1-hour picnic break and departure from the first car park)
Fairly steady climb, passing through the plateau with its Pottioks/horses that day, then the huts. The climb to the lake is gentle from the huts and passes through three plateaus (you always think you've arrived, but you have to climb a little further), but it's not that bad and, above all, it's worth it . There is even a spring on the opposite side of the lake where you can refill your water bottles!
In short, highly recommended in good weather.

A superb hike in perfect weather. Thank you to whoever planned it.
My GPS, starting from the Lamareich car park, gives me 14.8 km there and back to Lake Ansabère, which is a little more than the description (13.4 km).

A magnificent hike.
No problem reaching Lake Acherito.
At the pass, follow the author's advice and turn right to enjoy a beautiful panorama. But while you're at it, continue a few hundred metres further and you'll come to a small lake on the ridge with a very beautiful view. You can also go to the small summit on the left of the pass, which offers a bird's eye view of Lake Ansabère.

In high season, this route is very busy up to Lake Ansabère. The start of the route to Lake Acherito on the Spanish side is well marked.
A beautiful day under a bright sun, even a few vultures were there. I recommend the sheep's cheese from the Ansabère sheep farm.

The route description lacks detail once you have crossed the pass to reach Lake Ancherito. A superb hike in good weather. Magnificent. You will pass around ten izards on the Spanish side.

Great hike! Just a small issue at the pass, at the border... not easy to find the path... but you can find the solution quite easily with a GPS!
