Why go to the Trièves?

The Trièves is a high mid-mountain plateau, between 500 and 1,500 metres, hemmed in on three sides by the cliffs of the Vercors to the west and the Obiou range, in the Dévoluy, to the south and east. An hour south of Grenoble, it is a countryside of meadows, hedgerows and villages, dominated by the silhouette of Mont Aiguille, where mountaineering was born in 1492. Giono found inspiration here, and you understand why when you cross it on a June morning.

People come mainly from spring to autumn: hikes around Mont Aiguille, the Himalayan-style footbridges of Lac de Monteynard, visits to Mens and its museum, farmers' markets. The area suits families and lovers of slow travel, with few crowds and reasonable prices. High-summer days can be hot in the valley, but the evenings stay cool.

In winter, the Trièves does not go to sleep: Gresse-en-Vercors, a four-season resort at the foot of the Grand Veymont, offers a small alpine ski area and cross-country trails, and the paths can be explored on snowshoes. The rest of the Vercors massif, further north, has its own page.

Is the Trièves safe?

Mont Aiguille is not a hike: even the normal route is a mountaineering climb, to be done with a guide or an experienced leader. Around it, the trails along the Vercors cliffs run close to sheer drops; stick to the waymarking. Swimming is strictly forbidden on the whole of Lac de Monteynard-Avignonet, because of the watersports and changing water levels. The Himalayan footbridges are open all year round, but the path becomes muddy and slippery after rain, and the thermal wind picks up over the lake in the afternoon. Dogs are not allowed in the Hauts-Plateaux du Vercors nature reserve. In summer, storms often break late in the day. Emergencies: 112.

Mont Aiguille

Mont Aiguille is an outlying tooth of the eastern Vercors cliffs, in the commune of Chichilianne, cut off by erosion to the point of looking like a natural fortress. Its walls drop sheer on every side, yet its summit, at 2,087 metres, forms an almost flat meadow much like the alpine pastures of the high plateaus. Long known as Mons inaccessibilis, the inaccessible mountain, it already appears in the 13th century in the writings of Gervase of Tilbury among the seven wonders of the Dauphiné. On 26 June 1492, Antoine de Ville, a captain in the king's service, climbed it on the orders of Charles VIII using ladders and hooks, accompanied, depending on the source, by seven men or around twenty, and a notary: the feat, which Rabelais mentions in his Fourth Book, is regarded as the birth of mountaineering. It was not until 1834 that a shepherd from Trésanne repeated the ascent. On 27 August 1957, the aviator Henri Giraud landed his Piper on the summit meadow. The mountain lies entirely within the Hauts-Plateaux du Vercors national nature reserve, where bivouacking on the summit has been banned since 2022. Several climbing routes lead up it, including the normal route, feasible from May to October and best done with a guide.

Monteynard Himalayan footbridges

The Himalayan-style footbridges of Lac de Monteynard-Avignonet have made the name of this lake between the Trièves and the Matheysine, 25 km south of Grenoble. The Drac footbridge, 220 metres long, and the Ebron footbridge, 180 metres long, span the gorges of the two rivers that form the lake. The full circuit, about 13 km with 400 metres of ascent, takes 4h30 combining walking with a boat crossing of the lake, around thirty minutes for €8. The tourist office advises parking on the Trièves side, at Treffort, in the Salette or Combettes car parks, taking La Mira boat to Mayres-Savel on the far shore, then heading to the Drac footbridge, climbing towards the Serre de Lavana, the most strenuous section, and dropping down to the Ebron footbridge before returning to the start by the forest path or the panoramic track. Out of season or without the boat, the out-and-back to the Ebron from the Vignes car park takes 45 minutes, and the figure-of-eight loop around this footbridge alternates between lakeshore and a hillside track. Crossing the footbridges is free; the car parks charge from May to October, and the boat only sails when the lake level allows, usually from May to October. Since 2011, the Trail des Passerelles du Monteynard has brought thousands of runners here every July.

Lac de Monteynard cruise

Lac de Monteynard-Avignonet was created in 1962 by an EDF dam built at the foot of the Sénépy: 135 metres high, 230 metres long, 5 metres thick at the crest and 20 at the base, which you can view from a lookout point. The reservoir stretches for 20 kilometres at an altitude of 500 metres, in the shape of an upside-down Y whose two arms are the Drac and the Ebron, and in fine weather it takes on a turquoise colour that turns steel grey in the rain. A thermal wind picks up almost every afternoon over its central section, which makes it, according to the tourist office, the second windiest body of water in Europe after Lake Garda, and a hotspot for windsurfing, kitesurfing and wing foiling. At Treffort, the watersports centre also offers paddleboarding, canoeing and water play for children, and the EDF exhibition space at Le Môle presents the four great dams of the Drac valley. La Mira boat runs 1h30 guided cruises, at €18 per adult, and handles the crossings for the footbridge hike. Note: swimming is strictly forbidden on the whole lake, because of the watersports and the changing water levels.

Mens

Mens emerged in Roman times as a place of trade and markets, a role that shaped its character. In the 12th and 13th centuries, hemp, wool and iron working and large livestock markets drove an economy that looked towards the southern regions. In the mid-16th century, under the influence of its merchants, the population converted almost entirely to Calvinism; Lesdiguières, leader of the Protestant armies, took refuge here in 1573 and made it one of his strongholds. Nearly two centuries of religious strife followed, along with the exile of many families to Switzerland, Germany and the Netherlands. The 19th century saw industry decline, despite a silk mill opening at the end of the century. Today, the historic town lines up its cobbled lanes at the foot of the Châtel, known as Calvin's Bonnet, and lives off revitalised farming, green tourism and a lively cultural scene: craftspeople gathered in the old Bombyx factory, La Fabrique producers' shop, La Palpitante bookshop, Radio Dragon broadcasts and street-arts festivals. Here you can taste the Bouffette, a pastry made only in Mens.

Col de Menée

The Col de Menée, at 1,457 metres, straddles the communes of Percy, in Isère, and Treschenu-Creyers, in the Drôme, between the Vercors and Diois massifs. It marks the boundary between two worlds: to the north, the Trièves, its meadows and mid-altitude villages facing Mont Aiguille; to the south, the Diois, its Clairette vineyards and landscapes that already feel Provençal. You approach it from Chichilianne on the D7, a ten-kilometre climb from Mont Aiguille country; on the other side, the D120 descends for 22 kilometres to Châtillon-en-Diois. Hikers here cross the GR 965, named Sur les Pas des Huguenots, which follows the exile route of the Dauphiné's Protestants towards Switzerland and Germany. The Tour de France took it on stage 16 of the 1994 edition, between Valréas and L'Alpe-d'Huez, as a category 2 climb, with Frenchman Ronan Pensec first over the top. It makes a fine loop by car or bike from the Trièves, to combine with a tour round Mont Aiguille or a stop in Châtillon-en-Diois.

Lalley and the Giono trail

Jean Giono, the writer from Manosque, fell under the spell of the Trièves, where he regularly came on holiday, with family or with friends such as André Gide. He drew many texts from it, and his novel A King Alone is set in Lalley, where he used to stay. The tourist office quotes a passage from L'Eau Vive in which he describes this high plain of the Trièves bordered by four enormous mountains, all foaming with barley, oats and fir woods. In Lalley he met the painter Edith Berger, who became his friend and whose work now accompanies walkers: the 4.5-kilometre Edith Berger and Jean Giono trail sets up eight panels in the village and its surroundings, each presenting one of the painter's works amid the Trièves landscapes. The Espace Giono, a museum devoted to the writer, stands on the very spot where he lived, and the Musée du Trièves, in Mens, rounds off the visit with a room on the artists linked to the area. Lalley is also a good starting point for the Col de Menée and Mont Aiguille, a few kilometres away, and for the southern Trièves, facing the Obiou, the highest point of the Dévoluy at 2,789 metres.

How many days, and which itinerary?

A weekend for Mont Aiguille and the footbridges. Four to five days to add Mens, its museum, Lalley and the Col de Menée. A week to hike to your heart's content around Mont Aiguille and towards the Obiou.

weekend (2 days)

Day 1: arrive by train at Clelles-Mens, hike towards Mont Aiguille from Clelles or drive part of the way round the mountain via Chichilianne, night at the foot of the mountain. Day 2: Lac de Monteynard, La Mira boat crossing from Treffort and the loop over the two Himalayan footbridges, returning via Mens and its Bouffette.

4-5 days

Day 1: Mens, a guided tour of the town and the Musée du Trièves. Day 2: Mont Aiguille, a loop at the foot of the mountain or the climb to the Pas de l'Aiguille.

one week

Days 1 to 5 as above. Day 6: climb Mont Aiguille by the normal route with a guide, or walk the full tour of the mountain in two stages. Day 7: Gresse-en-Vercors and the climb towards the Grand Veymont, the highest point of the Vercors at 2,341 metres, before heading home. In winter, swap these for skiing at Gresse-en-Vercors and snowshoeing around Mont Aiguille.

Getting there and getting around

The TGV links Paris-Gare de Lyon with Grenoble in about 3 hours; from there, the Grenoble to Veynes line serves Clelles-Mens station, about 1 hour away. Note that Mens is 14 km from this station. By car, the A51 motorway runs from Grenoble to Monestier-de-Clermont, then the RD1075 crosses the Trièves towards the Col de Lus-la-Croix-Haute.

Once there, a car is still needed to link the villages, the lake and the trailheads. Hikes towards Mont Aiguille do, however, start from Clelles, and an e-bike is well suited to the plateau roads.

In winter, the roads to Gresse-en-Vercors and the Col de Menée call for suitable equipment: winter tyres or snow chains are compulsory in the Isère mountain zone from 1 November to 31 March.

Where to stay in the Trièves?

Budget: gîtes, B&Bs and campsites make up most of what is on offer, often in renovated old farmhouses around Mens, Clelles and Chichilianne. Village inns offer simple rooms with a shared table d'hôtes dinner.

Comfort: a few characterful hotels, such as the Château de Passières at the foot of Mont Aiguille, and the hotel-restaurants of Mens and Gresse-en-Vercors. The Trièves has few hotels: book early for July and August and spring weekends.

Our pick: a room with a view of Mont Aiguille in Chichilianne, to watch it turn pink at sunrise, or a night in a farm gîte facing the Obiou and the Grand Ferrand.

What to eat in the Trièves?

The Bouffette, a pastry made only in Mens, is sold in the town. Trièves producers sell cheeses, charcuterie, honey and jams, gathered together in producers' shops such as La Fabrique in Mens.

Dauphiné cooking dominates the tables: gratin dauphinois, ravioles, Bleu du Vercors-Sassenage from the neighbouring massif, walnuts and fruit tarts. In summer, Terre Vivante serves organic food in its gardens.

Allow €15-26 for a main course in the village inns. For a picnic at the foot of Mont Aiguille or by the lake, stop at the producers' shops in Mens.

Yes, by several climbing routes, including the normal route, feasible from May to October, which remains a mountaineering climb to be done with a guide or experienced leaders. Bivouacking on the summit meadow has been banned since 2022. Without climbing, walking round Mont Aiguille shows you all its faces.

Do you have to pay for the Himalayan footbridges?

No, crossing the Drac and Ebron footbridges is free. The lakeside car parks charge from May to October, and the crossing on La Mira boat, which lets you do the full loop, costs €8 for anyone over 4 and can only be booked online.

Can you swim in Lac de Monteynard?

No, swimming is strictly forbidden on the whole lake, because of the watersports and changing water levels. The lake is best explored by boat, kitesurf, windsurf or paddleboard, or on foot via the footbridges.

How do you get to the Trièves without a car?

By TGV to Grenoble, then by train to Clelles-Mens station, the starting point for hikes towards Mont Aiguille. For the rest of the area, Mens is 14 km from the station and the other sites require a car or a bike.
