The Combeloup National Forest above Murianette

This circular will take you to the heights of Murianette, with beautiful views of Grenoble and the Grésivaudan valley.
The climb is quite steep, but the reward of superb views is well worth it!
You will pass through Les Molinières and La Pérérée without crossing them, then cross Les Combes and the Combeloup National Forest before reaching Pressembois.
All these places are charming and the trails are bucolic!

Description of the walk

Departure from the large car park below the Murianette town hall.
The entire route is marked in yellow.

(S/E) Head south, going up the street to the nearby roundabout.

(1) Turn left onto Chemin de l'Église, towards "La Tour" (500 m). Walk 120 m past the church.

(2) At the fork, turn right onto the "montée de la Tour" and climb up to the first bend.

(3) Continue climbing, with courage, straight ahead on the Piste des Molinières.
The yellow markings are clearly visible (the other path on the right is private, so do not venture onto it). Continue until you approach the Molinières houses.

(4) At the crossroads, continue straight ahead, taking the south-east-facing climb towards La Pérérée and Venon. After about 600 metres, choose between two paths that lead to the same place. Stay on the yellow trail (path ascending to the right) or ascend the steeply cut path opposite, which also turns right after barely 30 metres.

(5) Turn right and continue towards "Venon (5.08 km)", "Forêt de Combeloup (2.88 km)", "Les Combes (0.36 km)" and you will come out on the Pérérée road (D291).

(6) Turn left for 30 metres, then right up the tarmac road to Combeloup, towards "Venon (4.72 km)" and "Forêt de Combeloup (2.52 km)".
Cross the hamlet of Les Combes and continue to the Combeloup farm.
The markings are still yellow.
The tarmac road passes behind and above the large farm and gives way to a stony path leading uphill, heading south-east, which is the entrance to the Combeloup State Forest. Continue for 250 m after the farm.

(7) Keep to the left (yellow signpost: "Forêt de Combeloup 1.63 km") and climb to the highest point of this hike, where you will come to the end of a large track.

(8) Turn right onto a new downhill path, then head west towards Fontaine Bénite (0.66 km) and Pressembois (1.16 km).
The path leads to a tarmac road, 100 m from Pressembois.
Head west on the uphill tarmac road until you reach a chalet below, the first house in Pressembois.

(9) Just after the chalet, turn right onto the double L-shaped cattle grid and head north on the descending path towards Champ Duret. (direction "Gières 4.49 km", "La Faurie 2.9 km", "Champ Duret 2.2 km").
Follow the path between the two meadows to the woods. At the edge of the woods, cross a second double L-shaped cattle grid.
Go down the path and watch out for the next fork, which is not obvious.

(10) Turn right, towards the east, at the crossroads (small 1 m high post), towards "Champ Duret 1.730 km". Continue on the descending path which winds once to the left, then once to the right.

(11) At the end of this descent, turn left, heading north, onto the descending path, without
crossing the Pisse-Vieille stream.
Set foot on Chemin de Panama, a somewhat long but bucolic path that heads southwest for over a kilometre. At the end of this path, you will come to a descending path.

(12) Turn right and take the path downhill towards the northeast. Head towards "Murianette 2.58 km" and "Pisse-Vieille 1.4 km". Continue for another kilometre until you reach a fork in the woods.

(13) Turn left (marked in yellow) to descend steeply for the last 400 metres until you reach the Pisse-Vieille stream at a place called La Perrière.

(14) Cross the existing bridge or, if the stream is too big, go lower down the street and then take the path going up, heading east, which leads to the tarmac road (Route de la Pérérée, D291).

(15) Cross carefully, go to the other side and follow the path uphill until you reach the hairpin bend on the same road.

(16) Turn left, heading north-east, and descend to the Murianette roundabout, which you passed on the way there.

(1) Turn left, following the same route as on the way there, and return to the Town Hall car park (S/E).

Notes

You will cross numerous streams. Do not do this route in rainy weather or the day after, as the descents are slippery.
On the practical side, we appreciated our high-top walking shoes, as the trails were wet!

There are many paths that cross each other: make sure you set off with the Visorando app activated, as we had a few (rare) problems choosing which direction to take.

At the point (15), if you are tired, you can take the road to avoid the last climb and, above all, the last descent!

Please note: in April 2024, there was some windfall due to recent storms. You have to go under or over it. The ONF is gradually clearing it away.

A very beautiful route, close to Grenoble. I agree with the previous comments about the mud, except that I did the route in dry weather. So I confirm that I would not recommend it after storms. Regarding junction 5, I followed the route and not the comments, so no problem. A short detour to our iconic oak tree in Venon is a must.

A very beautiful walk. Indeed, very muddy in some places.
We missed the fork described at marker 5 (distraction!). No matter, the trail led us to the beginning of the hamlet of Pererée. So we walked down the road to reach marker 6 (I didn't notice any errors at this point).
It's a shame I didn't read the reviews before setting off, as I would have understood why there was logging work (ONF) going on, even on a Sunday! We walked through mud for about 400 metres at marker 8.
As mentioned above, don't hesitate to take a detour to the Pressembois oak tree (described as "remarkable" at marker 9).
At marker 15: the path does not reach the hairpin bend in the road. A signpost (Tarrin) points to a path on the left to Murianette.

Superb hike, perfect description and round trip itinerary. Sunshine, shaded areas... a must-see stop at the Venon oak tree, a short 10-minute detour for a picnic.
A magnificent day.

There is indeed an error in the description in point 6. Not having read the comment beforehand (unfortunately), I took a nice detour through the forest; a little difficult but enjoyable.
Do not go past the Combeloup Farm, otherwise you will have to turn back, and the path is very muddy at the moment and difficult to walk on.
More details than on the Métrorando map, thank you.

Please note error in description: when you reach the Pérérée road, turn right, not left, and follow the road until you reach the next Conseil Général signpost.
PLEASE NOTE!!!!! The route between Combeloup farm and Préssembois is closed due to forestry work currently taking place at Rau des Pierres. This is very poorly signposted: there is a flat sign on the side of the path, forcing us to make a long detour and then take the road back up to Pressembois via Le Jappin.
Once in Préssembois, make a round trip to the remarkable oak tree.

Too bad, there were lots of tree trunks that we had to climb over.

Great spot to find wild garlic
Be careful between 8 and 9 large ONF forestry sites with numerous fallen and hanging trees. A sign indicates that the work should have been completed by the end of December, but it is still ongoing
Danger of hanging trees
Otherwise, a very beautiful route. Thank you to the writer.
