Description of the walk

From Vallouise, take the D994E towards Ailefroide and then Pré de Madame Carle. Park in the car park near the refuge chalet. The entrance fee to the car park is £2.

(S/E) From the Refuge de Madame Carle, take the path to the north-west towards the glaciers.
This crosses the Momie and Glacier Noir torrents and then winds its way upwards.

(1) At the third bend and the sign (altitude 2,040 m), leave the Glacier Blanc trail on your right and take the Glacier Noir trail on your left.
The trail climbs steadily in a straight line along the ridge of the moraine with the Glacier Noir on your left and the Ravin de l'Encoula on your right.

(2) The latter turns into a flat area at an altitude of 2,445 m, where you can see shelters sheltered by overhanging rocks where it is possible to bivouac. You are now at the Balmes de François Blanc, an ideal place for a picnic.

(3) Continue along the ridge to its end, the highest point of the route at an altitude of 2,550 m.

Return along the same route to reach the car park (S/E).

Practical information

I have made a video that gives a good impression of the atmosphere along this route.

This hike is not recommended for people who are prone to vertigo.

The path running along the ridge is exposed in places.

This route can become dangerous in wet or snowy weather.

I rate the difficulty as medium to high.

You will be hiking in the heart of the Ecrins National Park.

The Écrins massif is an exceptional area, open to all, with a rare natural, cultural and landscape heritage. To protect these treasures, the heart of the park is marked by blue, white and red flags, where regulations must be observed. Please read them when preparing your hike to help preserve this shared heritage at https://www.ecrins-parcnational.fr.

Beautiful hike – in fact, my husband, who is prone to vertigo, took the path on the right going up – the arrival point offers a magnificent view of Pelvoux, Coolidge, etc. – stony path – apart from the ridge, no particular difficulty

A magnificent hiking trail that is less frequented than the one leading to the white glacier. The ridge path in the second part should be tackled with caution, but there is another route below that allows you to avoid it. On the day of our hike, we were glad to have brought our fleece jackets with us.

Hike completed in mid-August in fairly hot weather. With two children aged 6 and 9.
The hike itself is not difficult. It is a technical hike rather than a physical one. You start with the crowd climbing up to the Glacier Blanc refuge before turning left, leaving 90% of the hikers behind. The climb is very steady and you can easily cover the 600m of elevation gain.
The view is magnificent on the last part, immersing you in a high mountain landscape.
It widens at the top, where you can stop for a picnic. There is also a small stream (at least when we were there) where you can fill your water bottle.
The only difficulty (often mentioned here) is the last third of the climb, as you are on a fairly narrow ridge that is relatively steep on the left. This is easy for adults who are used to mountain hiking. Our children managed it, but they are used to the mountains. Despite this, you need to take basic safety precautions.
However, there is an alternative route that we took on the way back: a path on the left (when descending) that avoids the exposed ridge.
In my opinion, this hike is just as remarkable as the one to the Refuge du Glacier Blanc, with the added advantage of being quiet.

A quick aside:
When I say that the hike is "easy", this is subjective. The hike may seem a little more demanding for some.
I say this because you see a lot of "tourists" at the start, in other words people who start the hike in the middle of the afternoon, with a bottle of water in their hand and wearing light shoes. This isn't a criticism, everyone has every right to enjoy the mountains, but many turn back at the first switchbacks when they see how steep the climb is.

The car park at Madame Carle's field was free and five chamois appeared there early in the morning.
There were few people on the trail early in the morning, but on the way back, we encountered everyone who was heading up to the refuges!
There were few people on the ridge trail, which was indeed deteriorating. You had to stay focused. It was impossible to pass each other: you had to move over a little into the grass where a parallel trail sometimes formed.
But the view at the end is superb. Definitely worth doing!

Caution, caution... Initially, the footbridge over the Black Glacier torrent was torn away during storms last June. As a result, you have to cross two branches of the torrent on a narrow plank, which may cause some people to give up. You need to have good balance, otherwise...
Higher up, the moraine is crumbling, leaving only a narrow path with a drop on the left as you climb... Again, those prone to vertigo may find it difficult to continue.
Otherwise, once you reach the top... It's beautiful!!!

Following the storms at the end of June 2024, the footbridge over the torrent has been replaced by a temporary footbridge and the start of the trail has been changed.
On the upper third of the ridge on the morraine, the trail is frequently narrowed with an impressive black glacier face. However, it is always possible to bypass these rockfalls by taking the slope on the mountain side.
At the top, the marmots are not at all shy, allowing you to observe them closely.

Yes, of course, as with many mountain hikes, there are sections where you need to be careful and, above all, take it slowly.
However, the path along the ridge is almost horizontal, and to see what it's like, there's nothing better than watching the video, which you can find herehttps://youtu.be/ZkCX_SzoEXI?si=0tUe2vWc...
as I film all my routes before creating the guides.

Hello
In my opinion, this hike is not suitable for everyone, it has to be said. We were a group of 25, and some sections of the ridges are really very narrow, with not even enough room to put both feet down, and with the drop below, this impressed many people. Three people turned back. I think there is a real risk of falling. The high number of visitors and erosion of this ridge are undoubtedly the cause of this risk.
Otherwise, you are sure to see a glacier, which is simply sublime and magnificent. Several chamois were frolicking happily on the glacier, but they were quite far away and you need binoculars to see them.
Thanks to the author for this hike

After the Glacier Blanc, here comes the Glacier Noir!

  1. toutelafrance is going to be there 🥰

A gradual climb of 15 to 20% on the moraine :-o It's quite a climb!
Indeed, if you're afraid of heights, there's a lower path, but you'd have to be really scared to take it!
A surprising hike, even if the view stays pretty much the same (I went all the way to the end). There's a beautiful waterfall at the end.

⛰ 8.5 km 661 m elevation gain/loss
⚡️ Highlights of the hike:
- Chamois and marmots!
- Ecrins National Park
- Glacier Blanc and Glacier Noir
- Pré de Madame Carle
- Mont Pelvoux and Barre des Ecrins

A fairly easy circuit, the supposedly vertiginous passages are not difficult but may impress those prone to vertigo.
Breathtaking views of some of the most beautiful peaks in the Écrins National Park in an impressive cirque

This hike complements the White Glacier hike and is a little less crowded. It offers beautiful views that you don't get when hiking the White Glacier. The trail is easier than the White Glacier trail (much less difficult on the legs) but more dangerous because of the drop.
(The drop is comparable to that on the crevasse trail that starts at the Col du Lautaret). You can avoid many of the tricky sections by taking small detours close to the ridge. In some places, there is even a path below on the right as you climb, which avoids the ridge (not shown on the IGN map). I didn't see if this path is present throughout the entire climb. Along this parallel path, there is a very basic monument dedicated to the memory of a mountaineer. There are also some very basic shelters made of stones piled up on the edge of a rocky overhang.

Trail on moraine that is more than degraded and of limited visual interest
The trail is so limited that there is a sign advising against using it in bad weather after about 20 minutes of walking

A beautiful walk along the ridge of the Black Glacier moraine, bringing you close to the high mountains without having to walk on a glacier. However, the path is narrow and eroded in places, so you may need to cut down to lower ground.
This walk is not recommended for those who suffer from vertigo
