This route offers magnificent mountain scenery.
The route is well marked and the trail is clearly visible.
It is easy to get stuck in mud just before the Brouquenat hut and a little further up as well.
In my opinion, the only tricky point is the change of direction after the Peyregrand hut towards the pass; look for the large rocks on the stream, the trail is just after, crossing the stream on stones provided for this purpose.
From there, keep an eye out for the cairns and yellow markers, otherwise you may end up zigzagging.
It's quite a long hike, so keep an eye on the time to avoid getting back after dark (which happened to me last autumn when the days were getting shorter).

A very beautiful hike, but the path becomes difficult to follow after the second hut on the trail. I recommend carrying a compass in case you lose your way (and I only lost it once) so you can make sharp turns. The trail is really hard to see, and it's very easy to get lost.
Once at Port de Siger, I crossed the ridge east of the port to reach Pic de Bagnels. Be careful on the way up and even more so on the way down! The return trip is hard on the knees, but the climb itself is not particularly difficult. Time to make the round trip via Pic de Bagnels: 11 hours and 15 minutes if you push hard to finish before nightfall!

Hello, everyone.
I did this route on Saturday, 17 September 2022. The weather was fine and the hike is beautiful, but you have to enjoy walking because it is very long (more than 10 hours of walking).
HOWEVER, DO NOT RELY ON THE DESCRIPTION FOR THE KILOMETRES AND TIMES MENTIONED.
I hike a lot and am used to walking for long days.
On this hike, there are yellow markings everywhere and in all directions because there is the old and the new route to the port of Siguer, which has also changed location, so there is the new and the old port.
From the Bouychet car park to the Blaou lake, it is 8 km and not 6.56 km. It takes 3 hours to climb for good walkers.
The Brouquenat d'en Haut refuge, before Peyregrand Lake, is clearly visible along the route, but not the Peyregrang hut. As a result, we climbed up the wrong side of the stream's meander, following the yellow markings but on the old route. This meant that our hike ended up off-trail as we arrived at Port de Siguer.
There are no signposts on this route.
Enjoy your hike, everyone, but be careful because the return trip is the most difficult part.

A hike to do once in a lifetime for the beauty of the scenery, but no more than that because the path is long and exhausting: so many rocks! Be sure to stop for a bite to eat at the Peyregrand pond, because you'll need the energy to tackle the climb up to the Col de Siguère. There's only one pitfall on this hike: getting mesmerised by the cairns and forgetting to turn left after the Peyregrand hut. And in the end, a pass that's well worth the effort.

The GR markings on the way up are not very visible, so it is easy to get lost unless you can spot the cairns. However, they are clearly visible on the way down.

This hike takes you through varied and beautiful landscapes. Walking on large rocks can be a bit tedious and requires constant attention. (Walking sticks are not very useful in these sections). The climb after the Peyregrand hut is a bit tough and the path is not very easy to find, but a few cairns and markings help you find your way. It is best not to start the section leading to the Peyregrand lake too quickly and to save your strength for the last part of the route... Once at Port de Siguer, you can easily reach Port Viell de Siguer (the old port) and the ridge overlooking the Blaou lake, which offers a majestic view of the valley.

This walk is rightly described as difficult, as the trail is a cattle track that is often rocky and uneven up to Lake Peyregrande. It is actually more challenging going down than up. But the scenery is well worth the effort. It's worth noting that, when they're not occupied, you can sleep in one of the two huts, one located a little upstream from the lake and the second (more rustic) before the climb to Siguer. We had tents, but the rain forced us to take advantage of this solution. Thank you to the Siguer town hall and the volunteers who maintain these modest but comfortable and often welcome accommodations! Lake Blaou was frozen and the surrounding area was covered with snowfields in mid-June. Bring crampons to cross the rivers without getting your hiking boots wet!

First impression: very long route, especially with 13kg on my back (bivouac required). The description wasn't very clear; I should have checked the altimeter. I thought I was at Peyregrand Pond, but in fact it was a stream that had dried up and looked like a pond. I'm at 2:10. I continue and come across the Peyregrand pond at 3:40, excluding breaks since the start. I'm exhausted and it's not over yet. A word of advice: it's better to bivouac here while the sun is still out. There are plenty of flat spots before the pond. It's ideal. I continue on and my troubles are not over yet. In terms of signposting, it's fine, the path is well marked, even if the yellow markings are sometimes missing. I arrive at what I think is the Blaou pond after 2 hours from the Peyrégrand pond and there I discover a small surprise pond. The sun has disappeared behind the mountain several minutes ago. I descend 20 minutes further down to set up camp. The spot is magnificent, even in the shade. However, I wasn't at Blaou Pond, which was a shame! It's a very long route, so my advice is to camp well before it and continue the next day to the famous Blaou Pond and camp again. The descent in the rain the next day was a nightmare. It was an exhausting descent on slippery rocks, slaloming between cow pats. And the path is stony all the way! + setback with the encounter with the herd of cows. 4 hours 45 minutes of descent in the rain, excluding breaks. Total journey time: 10 hours 45 minutes, excluding breaks. The journey time was slightly underestimated. That said, I had 13kg on my back and rain for the descent. Good luck!
