The Peñas de Itsusi loop via the Sentier des Moines

Magnificent hike with a picturesque climb to the Peñas, then a trail that runs along the cliffs where griffon vultures nest before descending.

⚠️ This hike should only be done in dry weather!The trail that passes through the cave (7) of the Saint who sweats is considered dangerous, even though it is part of the GR®10. See reviews.

Description of the walk

In Bidarray, cross the Nive and a few metres further on, cross the Bastan and follow this small road to the right for just over 4 km. Park at the Harruixea farm

according to a message posted by a hiker on 30/12/2019, the owner of the Bernatenea farm prohibits passage in front of his house. This hiker indicates that there is a path on the left, 150 m before the farm, which rejoins the described hike. I asked for clarification. I received two replies confirming this. The owner apparently marked out this new detour himself, without any difficulty. I have modified the GPS route approximately as it was not done on site.
Since summer 2021, according to some hikers, parking is prohibited along the road. Park at the end of the road near the Harruixea farm (few spaces available)

(S/E) Go back down the road on two hairpin bends to the Berntenea farm. 150 m further down, take a new path on the left to go around the farm. This path quickly joins the track shown on the original route. After passing a sheepfold, you will come to a stream.

(1) Cross it and pass over a second sheepfold. A few metres further on, the track veers to the left and you take a path opposite. This path follows a contour line. You reach a bridge and follow the track along a low wall. At the end, with a large tree in the middle and a cairn, you are at the start of the Chemin des Moines.

(2) The path is unmarked but clearly indicated, first by a dirt track and then by slabs and steps. The path is sometimes vertiginous but safe when climbing. You will arrive at the end of the Chemin des Moines.

(3) Turn slightly to the right. You will come to an enclosure and, at the end of it, a cross path which you take to the right, heading east and then north-east until you reach the Erreka stream.

(4) From here, there are several possible paths. Take the path furthest to the right, closest to the cliffs where vultures nest. The path first heads south-east, then east towards a small pass. Continue to another small pass. Here, on the right, a red dirt path branches off to the right, leading to a viewpoint with a ruin.

(5) Turn completely left, heading north, and follow a path on the hillside, descending slightly to join theGR®®10.

(6) Take it on the right; it is marked in red and white. ¹
Be careful on this section: theGR®® is vertiginous but safe if you watch where you put your feet. You will arrive at the cave of the Saint who sweats.

(7) Continue along theGR®® 10 until you reach the road.

(8) Go down the road and after three bends you will reach the car park next to the Bernatenea farm (S/E).

Notes

(4) Great place for a snack by the stream with several pools where you can dip your feet or more.

¹ Between (6) and the finish (S/E), theGR®®10trail is consistent with the IGN France map. This is not the case on the IGN Spain map. The OSM base map is more appropriate for both countries.

A welcome warning for the uninitiated!
However, this is an excellent, typically Basque route for fit hikers.
The GR10 section has been made significantly safer / risk of serious falls...
THANK YOU

A very beautiful hike that gives access to the cliffs where many vultures nest and offers stunning views. I wouldn't describe it as very difficult (like the 3 Couronnes, for example), but it is challenging because the climb up the Chemin des Moines and the descent via the GR10 require good physical condition and a good sense of balance. Avoid hot weather and humidity, but it's a real pleasure in mid-season when it's probably easier to park

The hike was superb, with many points of interest considering its difficulty and distance.
The very difficult rating is overestimated. You do need to watch where you put your feet, but having completed it in less time than expected and being four and a half months pregnant, I can say that it is not a very difficult hike. It is a hike where you have to use your hands once or twice.
As for parking, there is currently someone guarding the entrance to the access road to enforce the no parking rule along the river. The road is very narrow, so this is justified, but we did see people getting fined for not complying. A beautiful and very interesting hike with great views. You need to be in fairly good physical condition, but it's well worth the effort.*

A challenging hike, especially before reaching the summit, but magnificent with the vultures!
The cave is not worth seeing

It had been five years since I had done this loop, which is always superb. First of all, the author can rest assured that the GPS route is perfect from start to finish. Next, I was a little bothered by the tall ferns on both sides of the Moines trail, especially since they were soaked with water after the previous day's rain. The bottoms of my trousers were soaked. Otherwise, the climb was a bit harder (the weight of the years) and it was very, very hot on the descent from the GR 10, with not a shred of shade until I finally stopped at the Saint qui Sue cave. There were few people at this time of year, just a few GR hikers at the finish. A very beautiful walk among the vultures.

I have been doing this route regularly for many years. Before it was added to Visorando, the monks' trail was very little used and poorly marked. I can now find it easily with little risk of getting lost.
The descent route indicated is very exposed in places. Although it is now equipped with cables, you need to be sure-footed and have a head for heights, and it is not recommended in wet weather.
I therefore prefer to do this hike in the opposite direction, climbing via the Grotte du Sein qui Sue (between points 7 and 6) and descending via the Sentier des Moins (between points 3 and 2) or via a path a little further than point 3, which descends directly to the Itxusiko Borda farm.
This is still a very beautiful hike where you can see vultures in all seasons, but especially in May and June.

A very beautiful outing lasting 3½ hours. The slightly vertiginous nature of some sections is easily overcome, particularly thanks to the handrails installed on the descent to the cave!

Great hike, with a beautiful climb and breathtaking views. The trails are along ravines or steep slopes, so caution is advised. We saw vultures and waterfalls—it was magnificent!

the trail is now accessible directly from the Bernatenea farm, as a new access route has recently been created that bypasses the farm as closely as possible

We did a variation by climbing up to the plateau where you can join the GR: +1 km, +114 m elevation gain, +49 m altitude (694 m instead of 645 m). However, the difficulties are before and after the detour, as the path climbs after 3.8 km. This allows you to pass a hut and a beautiful picnic spot before seeing the vultures.
The route is rated "difficult" and this should be taken into account (equipment, experience of steep, rocky paths, which can be vertiginous and slippery)
Based on the route, the estimated time is insufficient; allow an extra hour.
I have photos but no link!

A beautiful hike surrounded by birds of prey.
No major difficulties, but avoid wet days on the monks' trail.
Please note that the starting point has been changed to comply with the parking restrictions along the Bastan.
Plan to park after the Bernatenea farm on the climb up to the Harruixea farm.

Hike done yesterday.
We couldn't find the trail right away at the start (we passed the house marked on the map as the starting point on the left).
Otherwise, it was a superb route with quite varied landscapes, including waterfalls, birds of prey, forest and more.
The entire first part is not marked, but the trail seemed well-trodden and we had no problems with the app.
Very nice hike 🌿 😊

And here we go again! I never tire of this route! The sky was clear and blue on this Friday in February. The climb up the monks' path had just been cleared, which seemed new to me. The ferns had died back, leaving the path clearly visible as it wound its way up the hillside. The young vultures were there to greet us with their acrobatics. The descent via the GR10 was completely dry and safe.
A perfect day...

See you next time, and thank you again for this route.

A very beautiful hike on a sunny winter day.

However, I can confirm that without the GPX route, it would have been difficult to do as there are no signposts.

We did the walk in 4½ hours with a picnic break and a 7-year-old child, but this route is indeed a little difficult
for people or children who are not used to it, as there are some steep climbs and descents.

The scenery is magnificent!
