Cabins at Combe du Fer and Serre du Play, circular trail

A hike through the forest and across the sharp limestone pavement, in the realm of the Vercors cave explorers, off the beaten track, with few markings and no signs.
The view opens up between the two huts, offering a spectacular view of the wild Vercors.
The climb to the Combe du Fer hut from the car park requires a GPS and a map (offline!) as there are many paths and the various junctions are not described here.

Description of the walk

Parking in the circular bend of the D215. A large grassy area provides easy parking for many cars.

(S/E) From the car park, cross the road and go up the gravel path opposite. Always stay on the widest path, going uphill in the same general direction. You will pass a large horizontal path on your right, which will be your return route.

(1) Continue along the main path in the same direction. Further on, this wide path becomes a trail shortly before reaching the Cabane de la Combe du Fer.

(2) Look for the entrance to the chasm.
With your back to the hut and the chasm on your left, follow the path uphill. In the sharp limestone pavement, follow the cairns carefully. The path winds uphill a few times, then, after a short flat section, descends to the right. It is then marked by cairns and blue markings. The view then opens up. Reach the Cabane du Serre du Play.

(3) Turn right and descend via a well-marked path, which becomes a track at an altitude of 1365 metres.

(4) Follow this track, which becomes a good path through the forest. Continue downhill.

(5) Cross a grassy strip, then stay on the same path and continue to a fork.

(6) Take the grassy path on the right towards a clearing, cross it and exit via a path that climbs briefly into the forest, then immediately levels out on the left. Follow it (blue and red markings), a slightly undulating path. Join the large gravel path uphill at the initial fork.

(1) Turn left to descend, following the same route as on the way up, on the gravel path, and return to the car park (S/E).

Notes

No water to my knowledge.
Take care when walking on the sharp limestone pavement.
The well-marked trail between the two huts does not appear on the IGN map, but only on OpenStreetMap. The GPS track will compensate for this omission.

This route passes through a protected area, which may be subject to special regulations:

A beautiful route mainly through forest. The GPX track is helpful when you are unsure which direction to take.
The passages through the rabbit warrens are difficult to spot. There are many crossroads, which is why the GPX track is important.

We love walking in the forest when there are very few people around. That way, we can see and hear the forest come to life.
A very beautiful and pleasant route.

Thank you for this route, which I found easy to follow, but I would have liked to know the origin of the name "combe du fer" (iron valley).
Was there an iron mine there, as I've heard? I couldn't find anything about it online.

Hello, this route is nice, even if the start is quite steep, this hike is really enjoyable. Suitable even for older children.

A superb hike through the woods, except for the section between the two huts, where you can enjoy a superb view of the Villard de Lans plateau to the north and the high plateaus to the south. The route was followed using a GPX track, which was fortunate as there were no markings. Care was needed when crossing the sharp limestone pavement.
I only met four other hikers along the way.

Hello,
Nothing to report, very beautiful hike, effective and visible signage. Mostly walking in the forest. Pleasantly surprised to find the first refuge in superb condition, clean and well-equipped.
Nothing to say, very beautiful site, not many people on the hike. There is a superb chasm at the first hut that sends cool air your way, which is pleasant in this heat (32°C).
Thanks to the team.

We did this hike in gloomy weather with strong winds. The wind only bothered us when we arrived at the Serre du Play hut. The route is quite varied, only the beginning and therefore also the end (since we return by the same route) seemed a little long to us. To cross the sharp limestone pavement, you need to follow the cairns as indicated in the description. There are no dangers on this hike (I mention this because, for example, I am afraid of heights). The Combe du Fer hut is very well maintained and apparently often visited, as there is a guest book.

The passage over the sharp limestone pavement is a bit technical,
Be sure to descend into the cave at the iron hut... bring a headlamp
Did not see any ibex on the Tête des Chaudieres or the Balme rocks

Pleasant day

Overall, it should also be possible to walk with snowshoes without any risk of avalanches.
