Piquet de Nantes and Tabor circuit

The Piquet de Nantes (2,215 m) and the Tabor (2,389 m) near La Mure in Isère are the two highest peaks in the Tabor massif and can be reached separately, but the route proposed here connects the two peaks via a trail that gives an almost high-mountain feel while being easy and very pleasant. It takes only an hour and offers a circuit with beautiful views of the Matheysine lakes and the surrounding mountains.

Description of the walk

The start is at the end of the car park at the Saint Honoré 1500 resort, about 45 km south of Grenoble via the Route Napoléon.

(S/E) Follow the path down into the meadow below. A group of yellow signs, visible from the start, indicate, among other things, the direction of Tabor and Piquet de Nantes, which we follow.
After a fairly steep climb of about 200 metres, you will arrive at a path opposite a water tank. Follow this path to the right. After a hairpin bend and about 500 metres from the start, you will arrive at a place called "Les Alisiers".

(1) There are two directions: Piquet de Nantes to the right and Tabor straight ahead. We will turn right and return to this same point via the other path on the descent from Tabor.
The path is very wide and gently sloping in the first part, winding its way up to the ridge. As on the rest of the route, there are regular signs, yellow markings and cairns: it is virtually impossible to go wrong. The last part of the climb is steeper and a little slippery, but after about two hours we arrive at a place called "Chaurousse" at an altitude of about 2,160 metres (not 2,200 metres as indicated on the sign).

(2) On the right, towards the south, is the path that takes us to the Piquet de Nantes in about 15 minutes (a cross is visible at the summit).

(3) After admiring the view, we head back towards Chaurousse and take the path north, which will take us to the Tabor, more or less following the ridge. The path is fairly well marked and has numerous yellow markings. We rejoin the path we will take on the descent about 50 metres before the summit of the Tabor.

(4) After stopping at the summit, we descend the trail northwards, following the ridge to a small pass.

(5) The path on the left is less visible but continues downhill for about 20 metres before a hairpin bend. The rest is fairly straightforward, with a clearly visible path marked with yellow markings and cairns. After passing through a hollow ending in a few metres between two rocks where you will need to use your hands, follow a stream northwards.

(6) The stream is first on your right, then on your left, without staying in its bed. It then heads left just before a small hillock and quickly joins the sign near the small Charlet lake, which you can visit but is not particularly interesting.

(7) A few metres after the sign, the car park is visible and the path leads us in that direction.

(8) Crossing the Jonche.

(1) You will arrive at a place called "Les Alisiers", where you can descend via the same path you took on the way up or take a shortcut on the right that will quickly take you to the reservoir and then to the car park (S/E).

Notes

- Walking sticks may be useful, especially on the descent where some sections can be a little slippery.
- The circuit can of course be done in the opposite direction, which is also very pleasant, but I would not recommend this for a first visit as the start of the connecting path between the two peaks is not very visible from the Tabor and the correct route is not as easy to follow.

Remarks:
- If you look at the altitudes on the curve, you will probably see that the altitudes are incorrect (2,389 metres for the Tabor, 2,214 metres for the Piquet de Nantes), but the 1,000-metre elevation gain indicated is correct.
- The circuit is classified as part of the Taillefer massif, but this is only because the nearby Tabor massif is not included in the list.

Worth a visit

Landscapes (see photos):
On the way up, there are beautiful views to the west over the Matheysine lakes in the foreground and the Vercors in the background.
From the Piquet de Nantes, the view to the south and the Dévoluy is completely unobstructed, as is the view to the east and the Taillefer massif.
From the Tabor, we also have beautiful views to the north (Chartreuse, Belledone).
Animals:
At any time, you are likely to see groups of griffon vultures, which come from the Vercors, located about 20 km away as the crow flies.
With a bit of luck, but more often in the early morning or late afternoon, you may encounter chamois or mouflons.
Extension of the circuit:
The hike passes by a landmark called "Lac Charlet", which is shared with the "Le Pérollier via the Devil's Trail" route. The more adventurous (about 7 hours of walking and 1,300 metres of elevation gain) can combine the two routes and thus pass by the three main peaks of the massif.

The suggested route allows you to warm up gradually on a moderate slope, making the climb easy and starting with the Piquet (round and grassy) before discovering the Tabor (steep and rocky), which suited me very well
The view is incredible all the way between the two peaks (if you look closely, you can even see the Rif Bruyant lake on the opposite side of the valley, a little north of Coiro) and the sight of vultures circling above the ridge is magnificent!

Completed on 31 July 2025 in reverse (starting with the ascent of Tabor) to tackle the steepest section first.
The view of the Écrins from the summit of Tabor is magnificent.
You can enjoy the panorama during the descent, which is a slippery rocky section but with good shoes it's no problem (without poles, in my case).

Magnificent hike, done in the direction indicated. Thank you for the advice!
Incredible views all along the way.
We did it on a very hot day and were a little worried about being in the sun the whole time, but with the altitude it wasn't too bad, even though there isn't much shade.
Two possible bonuses:
'Urbex' in the abandoned buildings in St Honoré for street art enthusiasts
Swimming on the way back at Lake Pierre Chatel (or Petichet)

Made in reverse, as many recommend. Tabor first. Lots of skiers, including alpine hunters in training. Then crest and Piquet de Nantes. I think this route is better because you get a better view on the way down, whereas from the Piquet de Nantes, Tabor seems inaccessible. Crampons then snowshoes about halfway up.
The descent from the col is not easy at first because of the snow: steep slopes and no visible signs. I didn't find the trail again until further down. I cut the laces several times: it's sometimes acrobatic because the snow alternates with the vegetation. 4:15 plus 30 minutes for refreshments at the Piquet de Nantes.

I'm quite happy with visorando, I haven't stopped because I don't want you any more, but "my" hiking season is over for this year, and it bothers me a bit to contribute for a year when I'm using it for 6 months, do you have any ideas?

Route taken in the opposite direction to that indicated by the author: access to Lake CHARLET, apart from being of little interest, is "watched over" by patous dogs. Some people with children turned back, so the hike was of little interest to them. On our guard, because I've already been bitten badly, we crossed, making a fairly large diversions via the sheepfold to catch up with the path. The rest of the way, from point 7 to point 3, is very beautiful with its views, particularly of LAVALDENS. On the other hand, the descent from point 2 to SAINT HONORÉ is extremely difficult: the upper part is very stony, and you can't see the end of it, with huge switchbacks where the difference in altitude is practically zero.

Walk as described. The path is clearly visible and marked in yellow. A wide variety of scenery on the way up to the Piquet de Nantes, the ridge to reach the Tabor and the descent. A great day out !
The path on the descent after Lac Charlet is very busy and there are many variations that make it difficult to read the true trail.

There is no problem accessing the Piquet de Nantes.
We continued on to Tabor (2389 m). The path is very well signposted. The climb is fairly easy.
The descent is towards Lac Charlet. And back to the starting point.
All in all, 950 m of ascent and 13.5 km to complete this loop.

A very nice hike in the opposite direction to the one suggested. The climb indicated becomes the descent, which is an advantage as this part is long and monotonous. What's more, the descent of the Barres ridge from the Tabor is magnificent - you're in the sky facing the Vercors and the Dévoluy. Magnificent panorama from the summit, thank you!

On foot, on snowshoes, in late spring (for the rhododendrons in flower), or in August, this hike is always so beautiful and wild, both during the climb and for the panorama at the summit. I've done it both ways, preferring to start at Tabor, as it makes for a relaxing descent. On the other hand, the climb is not to be underestimated!
