Col de l'Alpette

Very pretty hike in the foothills of Granier. At the summit, there is a large plateau ideal for picnics, with views of the surrounding peaks and Mont Blanc in good weather.
An easy family walk, done with a 3½-year-old girl who is used to walking, as it is quite steep.

Description of the walk

Park in the car park in the hamlet of La Plagne.

(S/E) There are two possible starting points from the hamlet of La Plagne (on the right before the Col Granier coming from Saint-Pierre-d'Entremont):
- either to the right at the fork before the hamlet (Col de l'Alpette signposted, distance 2.2 km, time 1 hour 40 minutes),
- or from the top of the village, you have to walk through the village to find the start of the path (distance 1.3 km, time 1 hour 30 minutes).
This is the option chosen here. The two paths meet fairly quickly.

(1) Turn right onto theGR®9towards Col de l'Alpette.
The first part is a stony path along the fields.
Reach the crossroads with the path coming from the forest road.

(2) At the junction, continue climbing on the left to reach the hairpin bends that lead to Col de l'Alpette.

(3) Turn slightly left and leave theGR® here to continue across the plateau.

(4) Follow the same route as on the way up to return to the Plagne car park (S/E).
Please note, however, that in wet weather some stony sections may be slippery.

Worth a visit

(3) Col de l'Alpette: Still very busy on 12 October, so it must be crowded in summer. However, the plateau is large enough to have a picnic away from the crowds.

A pleasant hike, with the opportunity to stroll through the mountain pastures when you reach the Col de l'Alpette pass.

A magnificent hike through the forest, ending on a grassy plateau visited by ibex.

However, this route clearly requires adequate physical fitness and equipment (good crampon-compatible shoes, walking poles, cardio training).

I would not classify it as "moderate" difficulty, but rather "difficult".
I hike regularly (without being an ultra-practitioner) and I relied on this classification, whereas if I had been better informed, I would probably have opted for a gentler route for my first mountain outing of the season.

The climb is clearly very steep (from 30% to over 80% in some places), rocky and slippery in wet weather.

A well-informed hiker is worth two and is happy 😄

A one-hour climb from the La Plagne car park, arriving to a welcome from ibexes!
Mont Blanc on the horizon!
A carpet of purple and white crocuses!
What more could you ask for?

Initially, it is preferable to take the right fork before the hamlet of La Plagne (Alpette signposted, distance 2.2 km, time 1 hour 40 minutes) – this path is less stony than the route starting from the top of the village (1 hour 30 minutes).

This is the second time I've done this hike. It's quite busy.
It's steep going up and down through the woods, but the arrival at the mountain pasture is worth the effort.

I did it again yesterday, perhaps the last hike of the year. Even though the weather was overcast, we could see Mont Blanc.
I was surprised that despite the humidity, it wasn't more slippery on the descent. In fact, most of the time there are earthy sections on the path where there is better grip.
It should be noted that since spring 2019, the trail has been partially rebuilt to facilitate the passage of herds. It has been widened and a few switchbacks have been added to the steepest sections (it is still quite steep except at the end).
As there are two options to point 2, you can go up one and down the other.

The climb is steep but pleasant in the cool forest during the summer heat. Beautiful views upon arrival at the mountain pasture. Numerous marmots present.

Quite a steep climb with rocky sections, but it's worth the effort. The plateau with cows and marmots is very pretty. It's a shame there are no chamois.

The access is quite steep in the woods, so I wouldn't recommend it for a family hike with young children. Make sure you wear suitable footwear.
Only the view of the plateau is very beautiful, with cows grazing and chamois in the surrounding area.

It is worth continuing for 15 minutes along the mountain pasture towards Granier once you reach the pass to admire the view of Mont Blanc.

The climb (and descent) is steep, but there is plenty of shade, especially in the morning.

Once you reach the plateau, you can continue exploring without any difficulty towards the east or south (GR9).
You can also climb up to the summit plateau of Granier, but there is a pass to cross, which is less family-friendly.

For shelter, there is a nice hut quite close to the pass, on the GR9, just opposite the sheepfold (see refuges.info).
The hut was renovated a few years ago by the municipality of Chapareillan.
There is water nearby.
