Cholonge is a small commune on the high Matheysin plateau, where the village, its outlying hamlets and a stretch of lakeshore share one broad mountain setting. INSEE’s 2023 reference population is 339 municipal residents, with 9 people counted separately, or 348 in total for the whole commune. These figures became legally effective on 1 January 2026; they do not describe just the village centre or the sailing base. The municipal planning notice places the plateau at about 950 metres and Cholonge along its eastern edge, with part of the Grand Lac de Laffrey inside the commune and the 2,141-metre Grand Serre rising to the east. The view changes quickly between open pasture, wooded slopes, farm hamlets and water.
A landscape shaped by water and pasture
Cholonge makes most sense as part of a chain rather than as a stand-alone lakeside resort. The local planning document describes four lakes arranged from north to south: Lac Mort, the Grand Lac de Laffrey, Lac de Pétichet and Lac de Pierre-Châtel. Around them, the same document identifies wetlands and ecological inventories at Laffrey, Les Vorges and the Tourbière de la Fayolle. Those listings help explain why the plateau feels more varied than its open fields suggest: wet ground, forest edges and ridges lie close together. A ZNIEFF is a scientific inventory, not by itself a visitor access permit or a statutory protection, so follow signs and respect private land and habitat boundaries.
The documented local story is modest but tangible. The Isère cultural-heritage service records that parish priest Didier Barruel had three hamlet chapels built at La Coirelle, La Bergogne and Les Josserands between 1680 and 1682. Their dates place them within a wider seventeenth-century wave of rural chapel building in Matheysine. They are markers of community and religious life in dispersed settlements, not evidence for a castle or an invented medieval foundation. Another living layer is pastoral work: in June 2026 the commune reported the renovation of the Chalet de Chopin, adding facilities and a covered equipment shelter to improve shepherds’ conditions on the alpages. That notice documents a contemporary investment; it does not supply an older construction date for the chalet.
Work, services and seasonal activity
INSEE counted 14 employer establishments in the commune at the end of 2024. The largest listed groups were commerce, transport and varied services, followed by agriculture, forestry and fishing; construction and public services also appear. This is a small local economy rather than a full visitor-service centre. In the 2025 equipment inventory, published with a 1 January 2026 reference, Cholonge has one hairdresser but no listed grocery, bakery, fuel station, general practitioner, pharmacy, school or library. The same statistical tourism tables show no classified hotel, campground or collective lodging; private rentals may not be covered by that count. Arrange groceries, fuel and overnight plans in advance, check current listings, and use the commune website for notices. Matheysine Tourism has information desks in the wider area, including La Mure.
The most direct way to read the countryside on foot is the signed loop to Le Crey des Vorges. Its official sheet starts at Route de l’Eglise in Cholonge and describes a forest circuit with views between hill and lake, crossing characteristic plateau hamlets. The published figures are 8 kilometres, 150 metres of ascent and about 2 hours 45 minutes at a moderate level. Parking is listed and dogs are accepted, but check trail markings and ground conditions before setting off. For a longer outing on wheels, the blue “Entre deux lacs” mountain-bike/e-bike loop begins at Camping des Cordeliers in Pierre-Châtel. It is listed at 16 kilometres and 406 metres of ascent, passing through Cholonge, Les Vorges, Pré Dessous, Troussiers, the Crey ridge and Pétichet. Its one-hour-fifteen estimate is an itinerary listing, not a promise of travel time.
Water and the high ridge
The Club Nautique de Cholonge brings sailing, dinghies, catamarans, windsurfing and paddleboarding to the southern part of Laffrey lake. Although named for Cholonge, the club’s visitor information says the lakeside base is reached from Saint-Théoffrey; use its current access instructions rather than navigating to the mairie. Its 2026 season dates have passed, so check the new calendar, reservations, equipment availability and wind restrictions before visiting. Above the lake, the Verticale du Grand Serre is a very different encounter with the same vertical landscape: the organizers describe its race at Cholonge as 1,811 metres long for 1,000 metres of ascent, usually scheduled in late September or early October. It is an event course, not a casual path to attempt without route and safety information. Nearby Laffrey, Saint-Théoffrey, Pierre-Châtel and La Mure make useful points for extending a plateau visit. Check weather, lake conditions, trail notices, transport, opening dates and event schedules before travel.
