La Pra - Croix de Belledonne - La Pra

The legendary summit of Belledonne is easily accessible in summer. The entire route is superb, whether it's the view of Lac du Crozet from Col de la Pra, the Lacs des Doménon or the view from the summit.

This walk is part of a multi-day hike: Traversée Belledonne Sud-Nord

Description of the walk

(S/E) Leave the refuge via the path behind it and climb up towards the Col de La Pra

(1) Enjoy the view of Lac du Crozet (emptied in summer 2018 for work on the dam). Start the climb northwards, following the well-marked path.
300 m further on, after crossing the stream, note the Pra water distribution block on the right.
Continue on the left flank, a steep climb over boulders. Well marked with cairns and some old red and whiteGR® markings, this section requires a little caution.

(2) When you reach Lac du Petit Doménon, continue along the shore to quickly reach Lac du Grand Doménon.
Then continue along the well-marked trail towards the rock that towers over the valley floor.

(3) Just under 10 metres high and topped with a pole, it is marked on the map at elevation 2474. It is often used as a landmark by a herd of ibex.
Turn right, heading south-east, onto the path that winds through the scree below the Grande Pente snowfield.
When you reach an altitude of 2,580 metres, where the slope becomes gentler, head east-northeast to pass at the foot of the red rocks. In high season, the path is clearly visible.

(4) Pass between the two lakes; the one on your left may still be half frozen at the end of August.

(5) Continue towards the Col de Belledonne, then the cross that you can see in the distance.

(6) At the Croix de Belledonne, with its beautiful 360° view, you may see climbers arriving from below or rope teams on the Pic Central.

For the return trip, descend in the opposite direction. You can wander a little towards point 4, and there are possible variations to reach point 3. Then head to the Refuge de La Pra (S/E).

Worth a visit

The Pra water distribution system was created so that:
- 2/3 of the water to flow towards Domène,
-1/3 flows down to Lac du Crozet and Lancey, following a 1898 court ruling that ended a water dispute in this area. At the time, hydraulic energy was booming.

Take the opportunity to locate the Col de Freydane pass, which you can take the next day (crossing Belledonne).

Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

Hello, I did the round trip hike with three teenagers aged 13-14 and 16
Parking des 4 Chemins (just before the Pré Raymond car park as there was no space) > Refuge de la Pra > Croix de Belledonne
We left the car park at 11 a.m. and arrived at the refuge at 3.30 p.m., taking our time. A magnificent hike with a break at Lake Crozet. Please note that swimming is prohibited.
The next day, we left at 8 a.m. and arrived at the cross at 10:30 a.m. A magnificent finish, with great views over the different valleys. A very rocky route. We met the Grande Traversée ski patrollers on the way back.
I recommend this hike, which is fairly accessible for experienced hikers.

Hike starting from the Pré Raymond car park (instead of starting from the La Pra refuge), round trip
According to my GPS: 22 km and +D 1538 m

Allow around 5 hours for the ascent (enjoying the magnificent scenery!) and around 3 hours for the descent. With an hour's break for lunch at the summit, it is best to set off by 8am at the latest.
This route is very popular (up to the summit), particularly with trail runners.
No technical difficulty (if there is no snow), but a hike for experienced and well-equipped athletes.

/!\ At point 3 on the map, be sure to turn right (cross the stream) and do not follow the "obvious" path that climbs towards the Col de Freydane.

Hike started from Pré Raymond instead of La Pra, round trip.
1,632 metres of elevation gain and loss, 23 kilometres and 7½ hours
The lakes are superb.
There were quite a few tents in the morning and tourists around the lakes on the way back
Some snowfields at the top but easily passable.
Thank you

Hike completed on Monday, 16 October. Hike from Col de la Pra to the Deménon lakes. I didn't climb up to the cross because it was already late in the day (I'll do that next year). At Col de la Pra, there is a sign that says: "Deménon lakes: 30 minutes"! However, it takes longer than that to reach the lake plateau. Crossing the scree slope, even though it is well marked with cairns, requires a fairly slow pace, especially in the last section. At the summit, there are a few small risky passages without equipment that require caution. The lakes are well worth seeing, much prettier than Lac du Crozet.

As pleasant and magnificent as ever. High temperature of 18 degrees at 9am. I prefer the climb done in June with crampons from the Domenons lock.

A classic route in the Belledonne massif (so we weren't alone...). We set off from the Refuge de la Pra at around 8.30am and arrived at the summit at midday sharp. There was still some snow on the middle section of the route. At the summit, there was a magnificent 360° view! I did this hike with my two nephews, aged 9 and 10. The descent to Freydières was the most challenging part (1,600m elevation loss)!

A very beautiful outing in the middle of the Doménon lakes (saw two chamois and a marmot on the way up); the snowfields are almost non-existent... Lots of people at the summit
On the descent, it is possible to reach the Col de Freydane: the start is marked by a large cairn and a narrow path across. Coming down the pass (on the Lac Blanc side), you can admire the north face and the Belledonne glacier.

:Very beautiful climb, partly on snowfields. 360° panoramic view at the summit.
Energy-intensive but well worth the effort.

A magnificent hike, definitely worth doing at least once!

Hike done on 14 August 2021, a Saturday and... lots of people! Do it on a weekday and outside of school holidays to avoid the crowds (if you like peace and quiet)

The hike started from Pré Raymond instead of La Pra. The Visorando app indicates an elevation gain of 1,630 metres and an elevation loss of 1,592 metres. The hike was done at a moderate pace (each person walked at their own pace) with a lunch break, photo breaks, etc. The round trip took a little over 10 hours for approximately 16 kilometres.
There was still a lot of snow even at this time of year, but it was easy to walk on (though walking sticks are a good idea)
A very physical hike, but well worth it once you reach the famous cross! The 360° view is breathtaking!

A superb hike that is not to be missed!
We left the refuge quite early (7:30 a.m.) and didn't see anyone on the way up, but we met quite a few people on the way down.
A few gentle snowfields to cross, ibex near the summit, climbers on the Grand Pic de Belledonne, magnificent views of the massif and the Oisans: what beautiful images!

Solo hike on 06/07/21 starting from Pré Raymond. 3 hours of climbing.
A few hikers up to the Domènon lakes, then I met two people who were cutting their walk short and coming down the Grande Pente snowfield, frightened by the alarming weather forecast. After that, no one else.
From the Domènon lakes, I made my way through the snow to reach the cross. At this time of year, there are no problems with crampons on these moderate slopes, so I left my crampons in my bag but took my ice axe to descend the slopes below the summit to the bottom of the Grande Pente.
A beautiful hike without much difficulty except for the 1,600m elevation gain.

The hike started directly from Col de Pré Raymond (1,370 m) instead of the Pra refuge. Over the course of a day, this amounts to 1,570 m of elevation gain: allow for a 5-hour climb at a good pace.

Despite it being August, there were lots of snowfields from around 2400m upwards, several of which we had to cross: it was very tempting to slide down some of them on our backsides (like kids ^^). These are easy to cross at this time of year. No major difficulties or challenging areas for those prone to vertigo (except perhaps the 10 metres to reach the cross).

Ibexes can be seen on the heights. For a weekday, it wasn't too crowded, but at the weekend it's certainly different.

i will cherish fond memories of this hike on my way to turning 18. I followed your description. I'm not an expert at reading maps, but thanks to meeting two experienced hikers, I managed to get through the slightly confusing section. They actually took a wrong turn themselves but reacted quickly. We headed towards the Col de Freydane and turned back along the balcony path. The rest of the hike and the return journey were straightforward, with good weather and visibility.
