Description of the walk

The departure point is after Névache. Continue along the road (D301T) that branches off to the right at the entrance to the upper town. Go through the two hairpin bends and arrive at the flat section in a right-hand bend where there is a chapel. Pass the other chapel a little further on, then take the dirt track that branches off to the left on the descent. Park at the bottom of the car park.

(S). Set off along the small path (GR®57) heading west, cross the Rately bridge over the Clarée river, then continue to a Y-junction.

(1) Leave the path that branches off to the right and continue along the small path that turns left a few metres further on and begins to climb. Follow this path to the Chalets de Buffère, ignoring the start of the return path on the left just before them.

(2) Continue up the valley, heading south, along a well-marked path that joins a track at the Col de Buffère.

(3) Take the less well-marked path that branches off to the left towards the south-southeast. This path climbs up the mountainside and becomes clearly visible. It continues to climb up the north face of the Grand Aréa, winding its way up a series of climbs and flat sections, to reach almost the summit on a ridge on the left.

(4) Continue climbing to the right for a few metres, ignoring the path that descends to the right, and reach the summit (2869m).

(5) From the summit, descend to the start of the ridge that heads north-west.

(4) Leave the path taken on the way up and continue a few metres along the ridge, heading north-west. Turn right, heading north-east, down the path that starts with a few small hairpin bends and then descends below the north-west face of the Grand Aréa until you reach a small pass with grass.

(6) Continue to the right towards the east, along a clearly visible path that winds its way around the foot of the Cristol ridge to the bottom of the descent.

(7) Ignore the path on the right that continues to the bottom of the valley and take the path that climbs slightly up the hillside towards the south-southeast for about 200 metres until you reach another fork.

(8) Take the path uphill to the left, heading north, to the Col de la Porte de Cristol, ignoring the paths on the right, where you will join theGR®5C.

(9) Descend north-east to the next fork at the bottom of the slope.

(10) Leave theGR®5C, which continues to the right, and take the smaller path on the left, which joins Lac Rond on the right-hand side.

(11) Continue downhill to Lac de Cristol, which you can walk around on either side, and rejoin theGR®5C.

(12) Head north-northeast along the path that follows the small Cristol stream on the right bank. After entering the wooded area, continue to the next crossroads (Cristol footbridge) at point 2092.

(13) Leave theGR®5Cand turn left. Cross the Cristol stream via the footbridge and continue north-west, ignoring the path on the right immediately after the footbridge.
The trail begins with a short climb, then descends behind you, before continuing westwards along the side of the Côte Rouge mountain.
After crossing the Buffère stream, rejoin the trail you started on, below the Chalets de Buffère.

Turn right at the descent to return to the car park via the same route as on the way up (S/E).

the descent via the eastern route is not for everyone, but otherwise the summit is well worth the detour. We then had a picnic by Lake Cristol before climbing up to La Gardiole. A beautiful day!

The most popular section is between the Porte de Cristol and the lakes. The path is perfect all along the route.
A beautiful hike to do in August when there is no more snow.

Indeed, there was snow: I did this route again on 3 October (in a circular loop, also passing by Lake Oule – magnificent!) and I took out my ice axe on the descent of the north face of Grand Aréa. The thin layer of snow made the going a little tricky. Photos available on request (but I haven't sorted them yet, so you'll have to wait ;-).

Compared to my previous comment: there was significantly less snow on 3 October 2022 than in 2020 at the same time, and the trail is very comfortable in places without snow.

This hike was superb. We had the opportunity to do it in early autumn, and the landscapes were diverse and magnificent. The colours of the larch trees at the beginning and end of the hike were breathtaking.
The only downside was that once we reached the summit of Grand Aréa, when we had to descend to reach the north face of the slope, the path was not really visible. We walked a few dozen metres on ground covered with small, unstable pebbles, and the snow still present in places hid the path we had to take. For safety reasons, we decided to take a long detour to the south, descending via the Petit Aréa and then rejoining the hike at point 8. This took us an extra hour and a half and added a good 150 metres of elevation, but we had no regrets.
It was a great discovery, despite the slight disappointment of not being able to go via the north side.
Thank you.

Beautiful climb to the summit of Aréa: very pretty valley.
But to descend on the other side, after the ridge, there was a small, very steep path in the scree (then no more trace), with large snowfields to cross (no footprints); I didn't dare go any further, despite the snow crampons I had brought with me! Very steep descent in the scree. No one in sight.
I'm a little disappointed not to have completed the circular route described, but as I'm only an occasional mountain hiker, I felt the risk was too great.

Emagnificent hike that I did in reverse from the point (2), straying slightly from the route to reach the unnamed lake below Crête de Cristol and also to reach the summit by climbing the couloirs on the western flank of the north-eastern rocky shoulder of Grand Aréa.

⚠️ Having done this variation in snow, I don't know if it's possible in summer; in any case, the level rises to Extremely Difficult. In snow, an ice axe and crampons are essential. In all seasons, a helmet is also essential. ⚠️

🗺 This variant first climbs the Vallon de Cristol, leaving the paths between (12) and (11) to follow the stream valley passing west of Lac Rond (see IGN topographic map). Then climb up to the unnamed lake at around 2525m and reach the Cristol ridge below the unnamed summit at 2640m. Reach point (6) by following the southern flank of the ridge, descending westwards. After passing over the northern flank and going around a small rock formation, leave the trail to climb up steep couloirs below the summit (5). Two easy climbing steps (3c max) allow you to climb to the summit. Then follow the documented route for the descent.🗺

⚠️ The IGN map is incorrect at the point (2) because it places the starting point of the level trail linking the Buffère valley with the Cristol valley at the Buffère refuge. The trailhead is actually about 100m to the north-east and 30m below. Setting off at night with my head torch, this error caused me to stray a little off-trail above the Buffère stream. Denis's route is completely accurate (and the OpenStreetMap Rando map is correct). ⚠️

The rocks of the Grand Aréa are spectacular from every angle. I will return to explore other possibilities once the snow has melted.

Many thanks to Denis for this itinerary.

A superb hike, a bit long perhaps, but very varied. Stunning scenery, with a 360° view from the summit of Grand Aréa. The climb up the valley is magnificent, after the Buffère refuge.

A very beautiful and varied hike, very few hikers up to the summit of the Grand Area, very different landscapes throughout the hike.
