Why Hike It

The Vanoise was France's first national park, established in 1963 expressly to protect what is now the largest glacier mass in the French Alps. The Tour de la Vanoise loops through the heart of it — crossing high cols with cold air rolling off ice fields, dropping into flower-filled valleys, and threading a network of mountain refuges that have sheltered alpinists and hikers for over a century.

What sets the Vanoise apart from its more famous neighbour, the Tour du Mont Blanc, is the quality of quiet. TMB moves through popular resort towns and shares its trail with hundreds of walkers on any given summer day. The Vanoise stays higher, longer, and quieter. You are almost always in the park interior, where motorised vehicles cannot go and the only sounds are marmots and the distant crack of ice. The route is accessible enough for confident intermediate hikers but demanding enough to feel like a proper alpine achievement.

Trail Snapshot

Highlights

Refuge du Col de la Vanoise. Perched directly at the main pass at 2,517 m, this refuge sits above the Plan du Lac lake with glacier views in all directions. Arriving here on a clear evening is one of the great simple pleasures in the French Alps.

Glacier de la Grande Motte. You do not walk on the glacier, but you walk beneath it, close enough to feel its air and watch ice seracs calving in a slow, inevitable collapse. The scale recalibrates your sense of time.

Wildlife density. The national park has one of Europe's highest densities of ibex and chamois. You will see chamois daily; ibex are reliably present on rocky ridges above 2,400 m. Bearded vultures — reintroduced in the 1990s — are regularly spotted soaring on thermals.

Refuge d'Entre Deux Eaux. A deeply remote refuge sitting between two glacial streams on the Doron valley floor. The isolation is total; the food is excellent. Worth scheduling a rest day here.

Village of Bonneval-sur-Arc. On the tour's most southerly point, this is one of the most intact medieval villages in the Alps — cars parked outside the walls, stone arches over alleys, fountain squares. It is the best lunch stop on the route.

Season Window

Mid-July to mid-September is the core window. The park's high passes hold snow into early July; Col d'Iseran and some northern cols can be dangerous before mid-July in a heavy snow year.

August is the busiest month. Refuges fill — pre-booking is essential, particularly in the first two weeks when French summer holidays drive demand up sharply.

Early September is the best balance of conditions: reliable weather, light crowds, the first colour on larch stands, and ibex bulls beginning their autumn rut.

Late September is possible for experienced alpinists comfortable with early snow and closures, but most refuges shut in mid-September.

Logistics

Getting there. Pralognan-la-Vanoise is served by bus from Moûtiers, which is on the Eurostar-connected rail line from Paris (via Lyon and Chambéry). Journey time from Paris is roughly four hours to Moûtiers plus 40 minutes bus.

Getting home. Same route out — the loop returns to Pralognan. Plan a bus at noon or mid-afternoon and you can make an evening train connection from Moûtiers.

Accommodation. The tour has staffed mountain refuges at each stage, with demi-pension (dinner and breakfast included) the standard booking option. Refuges fill in August — book every night before you fly. The park maintains a central reservation page; individual refuge websites also take bookings.

Resupply. Pralognan and Bonneval-sur-Arc both have small shops. Do not rely on in-refuge provision for snacks — carry enough for two days' trail food from each town.

Maps. IGN 1:25,000 Top 25 sheets 3532 ET and 3633 ET cover the full tour. The GR55 and GR5 markings guide most of the route; some connector sections use local park blazing.

Difficulty by Region

Pralognan to Refuge du Col de la Vanoise (days 1–2): Moderate. Well-maintained trail, straightforward GPS waymarking, classic alpine ascent with no objectively difficult terrain.

Refuge de Prariond and the northern valleys (days 3–5): Moderate. Longer valley and ridge days. Some boggy sections below Plan du Lac after rain; the trail is clear.

Bonneval circuit and Col de l'Iseran approaches (days 6–7): Hard. Higher elevation, steeper approaches, and the most exposed terrain on the tour. The descent from Col de la Rocheure can be icy in early season.

Return arc via Aussois and Polset (days 8–10): Moderate to hard. A satisfying mix of ridge traverses and valley walking to close the loop, with long descent days that test knees on loose terrain.

Permits and Rules

No permit is required for hiking the Tour de la Vanoise. Wild camping within the national park core zone is prohibited — you must arrive and stay at designated refuges. Bivouacs (one-tent, one-night, after 7 pm and before 9 am) are permitted in the buffer zone but not the core zone; check park boundary maps.

Dogs are not permitted in the park core zone. Drone flights require written authorisation from park authorities and are rarely approved.

Gear Watch

Shelter layers. Refuges are warm, but morning starts above 2,500 m require a down or synthetic insulating layer. Pack it accessibly.

Gaiters. Low-profile trail gaiters keep debris and early-morning dew out of boots on the grassy lower sections. Full gaiters are useful on early-July snow.

Trekking poles. Strongly recommended. The ascents and descents are long; poles spare your knees on the daily 800–1,000 m descents.

Sun protection. Alpine UV at 2,500–3,000 m is intense. SPF 50, lip balm, glacier glasses. Easy to underestimate for a week at altitude.

Cash. Several refuges do not accept cards reliably, particularly on cloudy days when satellite internet drops. Carry €100–150 in small notes for hut departures.

Hazards and Cautions

Afternoon storms. The Vanoise funnels weather from both the Mediterranean and Atlantic. Afternoons build fast. Start stages by 7 am and plan to be at or approaching the refuge by 2 pm.

Crevassed glaciers. You walk close to — but not on — glaciated terrain. Route markings keep you off active ice; follow them and do not improvise shortcuts toward the glaciers.

River crossings. Glacial streams are knee-deep and fast in early July. Most have footbridges but the Doron tributaries run high after multi-day rain. Ask refugistes about current conditions.

Ibex and chamois encounters. Animals in the park are habituated to hikers but should not be fed or approached. Young ibex occasionally block trails and must be waited out patiently rather than pushed.

First-Time Thru-Hiker Strategy

If you have walked the Tour du Mont Blanc and want a quieter, more wildlife-rich alpine loop, the Tour de la Vanoise is the obvious next step. It is slightly less manicured, the infrastructure is smaller scale, and the sense of being in a genuine wilderness is stronger.

Book every refuge before you fly. Unlike the TMB, there is no practical alternative accommodation if you arrive unbooked in August — no hotels in the park interior, no wild camping permitted.

Build in a weather day. The 10-stage itinerary fits neatly into 11 days with one flex day. Use it at Refuge d'Entre Deux Eaux or Pralognan at the end — both have enough interest to fill a day of rest.

Carry snacks beyond what the refuge sells. Lunch at refuges is available but expensive. A packed lunch from Pralognan's bakery, topped up at Bonneval's shop, keeps costs and dependency manageable.

Prioritise early morning starts. The light is spectacular on glaciers at 6–8 am, the air is still, and you build a comfortable buffer before afternoon weather arrives. The culture in Vanoise refuges strongly supports this — breakfast is typically 6–6:30 am.
