Mont Coin from Cormet d'Arêches

One of the most beautiful viewpoints in Beaufortain, accessible to all and close to the Pierra Menta! The path crosses magnificent flower-filled mountain pastures, dotted with the bells of Tarentaise cows. The flowers, marmots and rocks make for a varied and enjoyable hike. This short hike offers beautiful views of Mont Blanc, the Vanoise massif, in particular Mont Pourri, the pyramid-shaped Pointe de l'Aliet and Bellecôte.

Description of the walk

The walk starts from Cormet d'Arèches. To get there by car from Arèches, follow the signs for the Saint-Guérin dam, where you take the road on the left and continue straight ahead. The road turns into a track that you can drive on to Cormet d'Arèches, where you can park.

(S/E) Take the yellow-marked trail heading north, which follows the ridge above Lac des Fées, further to the left, and Lac de la Motte, to the right. The first stop is the Berger cross, clearly visible from the start.

(1) The Berger cross is located at an altitude of 2,159 metres, offering a beautiful view of the Vanoise massif to the south-east, in particular Mont Pourri, but also the Aravis range to the west with Lac de Saint-Guérin below. Continue along the path, north-north-east, towards the rocks that form a small gorge where you can have fun finding shapes.

(2) Fork in the path to see Lac des Marmottes. When you reach a Y-shaped crossroads, take the main path on the left, which is marked in yellow. On the right, you can take a short detour to Lac des Marmottes (2,265 metres).

(3) Cross the aptly named Plan de la Marmotte. If you pay attention, you will surely find a colony in the hollow above the small pools of water.

(4) The path arrives at a small pass. At this point, turn left and follow the ridge line that climbs towards Mont Coin. The yellow-marked path is not very well signposted, but you will quickly find it on the ridge line. From there, the climb to the summit begins. This is the most physically demanding part of the hike, but it is easily manageable if you pace yourself and, above all, it offers a superb view!

You arrive at Mont Coin, which rises to 2,539 metres, where you have a breathtaking view of Mont Blanc, Pierra Menta, Aiguille du Grand Fond, as well as small lakes and the Roselend dam.

(5) The return journey is in the opposite direction and is not particularly difficult, leading back to Cormet d'Arèches (S/E).

Notes

To get to the start of the hike, take the D218D road from Arêches, following the signs for "Barrage de Saint-Guérin".
Once you reach the dam viewpoint, take the road immediately on the left and continue uphill. Once you reach the end of the tarmac road, continue on the gravel track to Cormet d'Arêches. You can extend the walk by starting from Lac des Fées.

Worth a visit

Lac de Saint-Guérin offers a discovery trail accessible to all, allowing you to enjoy beautiful landscapes between mountain pastures, a suspension bridge and the deep blue of the lake.
Cormet d'Arêches is also the starting point for other hikes.

A very beautiful hike with a stunning view of the valley.
Once you reach the top of Mont Coin, the view of Mont Blanc is superb.
However, it's a fairly average hike rather than an easy one, due to the elevation gain and some sections that are difficult to climb and descend.

The view from the summit of Mount Coin is spectacular, especially the Pierra Menta, which I had never seen so close up before.

Hello,
There are a few slightly exposed sections between the rocks above the Croix du Berger, where the path is narrow for a few metres.
The height is reasonable and there are no technical difficulties, but if you are afraid of heights, you will probably not be able to pass these points, including the summit, which could be daunting if you are afraid of heights.
You can avoid them by following the track that climbs from La Chevalière and joining either point 2 or point 3. You don't have to go to the summit, as the view will already be magnificent. I hope this helps.

Hello,

I would like to go on this hike, but I am a bit prone to vertigo.
Which sections are tricky, please?

Thank you.

The landscape is already magnificent along the road leading to the car park.
You can park at the Coire refuge, but there aren't many spaces. Otherwise, continue on to Cormet d'Arêches, where there is a large car park.
There are beautiful views of the surrounding mountains and mountain pastures throughout the hike.
Not recommended for small children as there are a few tricky sections.
Tip: at point (2), take a short detour to Lac des Marmottes to see... marmots.
For an easy descent, and also to avoid retracing your steps, from point (4) head towards the Col du Coin. Below the pass, a track takes you directly back to the Coire refuge via La Chevalière.

With a beautiful view of Mont du Coin, we continued on to Col du Coin and Lac d'Amour at the foot of Pierra Menta. The climb up Mont du Coin is steep but well worth the effort. The return trip to Lac d'Amour brings the total elevation gain to 600 metres.

Hike with a group of nine people aged between eight and 77. We set off from the Col de la Coire, coming from Granier, and went as far as the Col du Coin and the summit of Le Coin in thick, cold fog. There were lots of people around because the Ultra Trail du Tour de Beaufortin was taking place that day, and the path was very muddy and slippery in places due to the rain over the previous few days.
A beautiful hike that delighted the participants. Return via the Chevalière trail.

Great hike with marmots to see.
Suggestion: Park at the Coire refuge rather than at the pass. Climb back up to the pass via the well-marked trail that cuts across the switchbacks to the pass and follow the ascent as described.
Then, after the summit of Mont Coin, return to point 4 (Mont Coin/Col du Coin fork), take the good path on the left and make a small detour to the Col du Coin. From the pass, descend towards the visible track and return via Plan Brunet and La Chevalière to the Coire refuge, completing a circular route.

A very beautiful hike. Not suitable for young children as there are some tricky sections. Magnificent views and lots of marmots. We climbed via Granier and parked at the Coire refuge car park.
To extend the hike, we went to the Col du Coin and then on to Lac d'Amour. It was great fun.
The hike is easy to follow as there are signposts at all the important points.
Best done in good weather.
