The Fort of Montavie

On the outskirts of the capital of the Alps, a circular route starting from Eybens provides access to the Fort de Montavie overlooking Grenoble. This is more of a walk than a hike, offering remarkable views of the three mountain ranges surrounding the Drac and Isère valleys: Belledonne, Chartreuse and Vercors.

Description of the walk

Park in the large car park at the swimming pool and stadium in Eybens.

(S/E) Begin a short climb from the car park, following the yellow markings that will be present throughout, but are very faint, to reach Rue Paul Mistral higher up and then walk along the castle's surrounding wall. Reach the end of this wall at a crossroads.

(1) Take the right-hand track (signposted Tavernolles) and follow it, keeping to the right at the crossroads serving the scattered houses. This will take you to another large crossroads in Tavernolles on the right bank of the Laprat stream.

(2) Cross the stream and turn left onto the street with the Auberge Napoléon opposite. Cross the D5 at the traffic lights with caution, as there is heavy traffic. Take the Route de Montavie opposite. Walk past the school and begin a steep climb. Leave the track on your right to reach a crossroads between the two power lines.

(3) Turn left onto the wide track, which is closed to motor vehicles, and continue up another steep climb, keeping to the right to reach a flat area. Continue to Fort de Montavie.

(4) Turn almost 180° to descend the forest track. After two large hairpin bends, rejoin the Route de Montavie at the power lines.

(5) Turn left (signposted Eybens Bourg) onto the wide path through the woods. Keep following the yellow markings, ignoring the paths on the right at each junction. You will reach the bottom of the descent on Avenue de Bresson.

(6) Turn right, cross Place de l'Église and then the D5 at the traffic lights (take care, heavy traffic) to reach the car park opposite (S/E).

Notes

There are fountains in Tavernolles, but as a precautionary measure, the water is labelled as non-potable.
At the junction of the D5 in Tavernolles, the Auberge Napoléon welcomed the emperor on his return from Elba, and hikers should also be able to find something to eat there.

In the middle of the week, there weren't many people on this route.
I enjoyed the mix of climbs and descents, the lack of tarmac, and even when there was some, it was on quiet sections.
Almost the entire ride is in the shade, which is very, very, even VERY pleasant at this time of year! 😊
I deliberately took the GR on the climb after Tavernolles. I think the path is nicer, but the tall grass and a few nettles and brambles on the climb reminded me that I was wearing shorts.
The fort is not open to visitors, but you can get close to it without any risk. And it's very interesting to see how nature is reclaiming its rights when you visit this site recounting the history of the fort: https://fortsteynard.com/fortmontavie.ht...
The descent to Eybens is peaceful. There are lots of mountain bike tracks and a few tricky sections when wet, but nothing dangerous.
You can take your time, unless, like me, you take lots of photos!
Bring water!!!

A pleasant hike on the outskirts of Grenoble, suitable for families and shaded (I did it on a hot day and didn't suffer from the heat), there are also three fountains along the route. I took water from the second one (the first one indicated that the water was not drinkable in Tavernolles).

Just something to bear in mind around this time (end of August 2023): construction work is underway above the swimming pool, which prevents you from starting the walk as indicated in the description. For the time being, you will need to walk around the construction site to reach the trail.

A very pleasant, gentle and easy hike that takes you through some beautiful spots. A real pleasure. The GPS track isn't perfect, but it's very easy to figure out which way to go and then get back on track without any difficulty.

A very pleasant route if you want to go for a short walk not far from Grenoble. The only slight downside is that on the first part, you can hear the road a little in the distance.

Thank you

A good route for a Sunday afternoon stroll. A short detour (150 m) to see the fort, but it's worth it.

Very good course at Fort Montavie in particular.
Part of it was still occupied by Airsoft players, who were very respectful of the site. We left them alone, as the site is huge!
For your information, on the way down, we wanted to see Montavie Castle further south,
Bad idea, it's private and very well protected by high walls. We came back through the woods, struggling a bit in the windfall. Give up on that idea!

A pleasant early season walk offering views of the three mountain ranges and the Grenoble basin.
It's a shame that such a building has been left to fall into disrepair

A very pleasant walk with a group of 20 hikers from GV Vizille.
Beautiful view of the three mountain ranges, we had superb weather.
The fort was taken over by guerrilla players, but they were very respectful of the site and the hikers.
Thank you for this guide. Michel.

A gentle walk, with no particular difficulties.
Starting point easily accessible (by bus) from the centre of Grenoble.
Lovely view of the city and surrounding mountains at point 5.
It's a shame that the site itself (Fort de Montavie) has been completely abandoned.

It's a 10-minute bike ride from my house (Échirolles), so it's really convenient.
Otherwise, the ride is nice, with beautiful views from the fort and even at certain points along the way.
However, I find the duration indicated on the website to be very generous; we completed it in much less time.

This walk's main advantage is that it starts very close to Grenoble and still offers beautiful views.

It mainly runs through woodland and partly along a tarmac road, but there is very little traffic (we didn't see a single vehicle on a Saturday).

Highly recommended for a family outing!

I didn't do the whole hike, but the part I did was good.
It would be good if, for certain places such as the fort, it was specified whether access by car is possible. I sometimes take a disabled friend to places of interest and I usually need to check the location beforehand. Road access was not very clear on the map. The fort is not accessible, but you can get to within about 300 metres by car and enjoy a beautiful view
