Set the elevation gain you know you can hold day after day: the tool places your nights on the real accommodation along the GPX track of the loop, then evens out the days. Starting point, direction of travel and bivouac all sit in the advanced settings. Pace and advice are covered in the full article.

Your plan is ready. How would you like to travel?
Good call!
Organizing it yourself is still the best way to make the loop your own, and the split above is a solid base. Book the refuges early, from spring onward for July and August. The GPX downloads under the profile, and staffing dates are on the GR54 refuges page. Enjoy the loop!

A July evening at the gîte (guesthouse) in Le Désert-en-Valjouffrey, two tables comparing notes across the dining room. One group is finishing the GR54 in 8 days and will be gone before dawn to link two passes in one go. At the next table, a hiker is on day nine with four left, and she is going up to the lakes in the morning before rejoining the trail. Same 188 km loop, same 11,000 m of elevation gain, two completely different treks.
How many days does the GR54 take? The guidebook answer is a round number: 12 days.
The real answer is a good deal more personal. It comes down to your daily elevation budget, the number of metres of climbing you can absorb day after day:
14 or 15 days with the alpine variants or a rest day
2 to 5 days if you are after one section rather than the whole loop (or running it!)
One small advantage you bring with you: you already think in kilometres and metres, so nothing on this page needs converting, and neither will the trail signs, the hut boards or the guidebook. The only conversion to run is the currency. Everything is priced in euros, and at the usual CAD rate you can budget roughly 1.45 to 1.55 Canadian dollars to the euro when you are sizing up refuge nights (55 to 65 EUR half board is standard).
The French hiking federation puts the loop at "about a dozen days". The national park publishes four reference itineraries of its own, from 12 to 15 days:
The four reference starting points, 12 to 15 days
Start
Stated length
Stated distance
Stated elev. gain
Bourg-d'Oisans
13 days
194 km
+11,950 m
La Chapelle-en-Valgaudemar
12 days
184 km
+11,650 m
La Grave

186 km
+12,500 m
L'Argentière-la-Bessée (starting from the train station)
15 days
223 km
+13,500 m
The starting point changes, the loop does not: from Bourg-d'Oisans, La Grave or La Chapelle-en-Valgaudemar it is the same GPX track of 188 km and 11,000 m of climbing. The stated figures differ from line to line because each guidebook folds in its own variants and its own way of measuring. Only L'Argentière-la-Bessée genuinely lengthens the route: the town is not on the loop, so the itinerary adds the connection from the station. The 12 to 15 day spread is therefore about how the days get carved up, not about loops of different lengths. The rest of this article is about narrowing it to your own fitness and the time you can actually take.
The math that holds up: a GR54 at your own pace
Dividing 188 km by a walking speed gives you a number. It does not give you a plan that survives this terrain.
On the GR54 the elevation runs the show: 11,000 m of cumulative climbing over 13 passes, the Aup Martin at 2,761 m among them, and every metre of it back down again.
To size your trek, divide 11,000 by the elevation gain you know you can absorb day after day with a pack on. Not the figure from your best single day out, the one you can repeat for a week straight.
1,500 m of climbing per day: 7 to 8 days
1,200 m per day: 9 to 10 days
1,000 m per day: 11 days
850 m per day: 13 days
Running that math before you leave is what stops you discovering on day four that the schedule was optimistic, right as the most committing half of the loop comes up.
The division stays an approximation, since it assumes you can stop anywhere. On the ground you sleep where there is a refuge (a mountain hut) or some other accommodation: a village, a lodge, a campground. That is exactly what the planner at the top of the page handles: you enter your elevation budget, it places your nights on the real accommodation along the track, then evens out the days between them.
Finding your daily elevation budget
This figure is your cruising rate: the elevation gain you can take in a day and do again tomorrow, and again the day after. That distinction changes everything, because on a multi-day trek fatigue accumulates. Soreness peaks 24 to 48 hours after the effort, and a night in a refuge does not repair you the way your own bed does. The day a schedule cracks is rarely the first, it is the third or fourth.
Three ways to find yours, from quickest to most reliable:
Work back from a recent outing. Take your biggest day of the past few months, the one you finished with something in reserve. Take 20 to 30 % off to account for a full week in a row with a multi-day pack, and you have an honest starting figure.
Place yourself by profile. Our article on hiking difficulty levels sets out ranges based on how active you are at the moment. Caught between two lines, take the lower one: you can always add on the way round, the other direction is far less forgiving.
Test it over three days. If this is your first time on a long multi-day trek, a short itinerary is the best test bench there is, and day three is the one that talks. A weekend based in a refuge in the Écrins, or a three-day loop in the Valgaudemar, is enough to take your own measure before committing two weeks.
The terrain then corrects that math. The schist descents off the Col de la Vaurze and the Col de Côte Belle get taken step by step, and cable-protected sections do not get rushed. One thing worth flagging if your reference is the Rockies or the Chic-Chocs: the descents here are longer and looser than the ascents are steep, and they are what tends to slow people down.
A 14 kg bivouac pack does not come down a slope the way an 8 kg refuge pack does, either.
The planner at the top of the page reasons over the whole loop. For a single stage, the alpine club method works just as well on paper: take the longer of your horizontal time and your vertical time, then add half the other. Try it against a day you already know well and you will quickly see which formula matches your legs.
The GR54 in 7 or 8 days: the fast version
A week for the loop means 24 to 27 km and 1,400 to 1,600 m of elevation gain per day, with no recovery day anywhere in it. Not a format to improvise into: it is for hikers who already string big days together and know how their body handles three long ones back to back.
In practice, a 7-day version means merging several of the guidebook's stages into single days and, in a couple of spots, leaving the waymarked GR for more direct valley-to-valley lines. The 8-day version keeps the same logic with a little more slack, and it is often the better compromise for fast walkers who would rather reach a refuge every evening than finish stages by headlamp.
The GR54 in 10 or 11 days: the format we recommend
At 17 to 19 km and 1,000 to 1,100 m of elevation gain per day, the days run 6 to 8 hours of walking. You reach the refuge mid-afternoon, which leaves margin on the mornings when the forecast forces a dawn start. This is the rhythm we suggest most often to a regular hiker.
Below 12 days, simply merging guidebook stages stops working: the days come out uneven, with 10-hour links appearing. The better move is to re-cut the loop around different overnight points. Two examples that balance a 10-day tour nicely: sleep at Besse-en-Oisans rather than Clavans-le-Bas on the first night (1.5 km and 150 m of climbing more, but a shorter second day), and break the Valgaudemar crossing at the Refuge du Clot Xavier Blanc, beside the Séveraisse, between Vallonpierre and Les Souffles. All four of those overnight points are in the planner at the top of the page: set the budget around 1,100 m and it distributes the stages between them itself.
One merge to avoid unless you are unusually durable: linking Le Désert-en-Valjouffrey and the Lac de la Muzelle without a night at Valsenestre. That day goes past 2,000 m of elevation gain and puts you on the Col de la Muzelle late in the afternoon, exactly when the cumulus start building.
A last piece of advice that costs one line on a vacation request: book twelve days off for an eleven-day loop. Not to walk an extra day, but so you are not travelling home the morning after you finish. The last stage often ends in the early afternoon, and going straight onto a road or a train closes the trek a little abruptly.
That twelfth day fills itself. A morning with your feet in the Séveraisse at La Chapelle-en-Valgaudemar if you finish on the south side: the water comes straight off the glacier, so nobody stays in long, but it is exactly what legs that have swallowed 11,000 m are asking for. On the north side, the thermal baths at Le Monêtier-les-Bains sit directly on the GR54. And there is the terrace version, a coffee and your photos, with one habit worth picking up: get the map out and put a name back on every pass you crossed and every summit you spotted from the ridges. That works well with two of you, and much less well two weeks later, once the valleys have run together. It is also the day the phone numbers swapped in refuges turn into plans for next summer.
Worth mentioning too, since it is common practice on the GR20: split your Écrins loop in two. One year from La Chapelle-en-Valgaudemar to Bourg-d'Oisans, say, and the far half the following year.
The GR54 in 12 or 13 days: the guidebook split
The classic split from Bourg-d'Oisans runs to 13 stages of 3 h 30 to 9 h of walking, with a night in almost every valley. We break them down one by one, with distances, elevation gains and GPX tracks, in our main GR54 article.
That rhythm, around 15 km and 850 m of elevation gain per day, frees up the time short formats give away: the detour to the lakes below the Glacier d'Arsine, the Lac Noir and Lac Lérié on the plateau d'Emparis, a late afternoon beside the Lac de la Muzelle, an early morning watching chamois, and margin against thunderstorms.
To save a day on this split without forcing anything, one merge really works: the descent from the Lac de Vallonpierre to La Chapelle-en-Valgaudemar (3 h 30) followed by the climb back up to the Refuge des Souffles (4 h 30). Eight hours of walking in total, with a resupply (or a restaurant) at La Chapelle in the middle of the day. Bonus, the climb runs in forest shade all the way to the Refuge des Souffles.
The GR54 in 14 or 15 days: alpine variants and rest days
Two good reasons to go past 13 days:
The alpine variants, on the itinerary from La Grave (14 days): the glacial Lac de l'Eychauda by the Pas de l'Âne and the Col des Grangettes, then the Refuge de l'Olan and the Col de Colombes above the Valgaudemar. More elevation gain and more technical ground, but a way off the busiest trail. Even so, you are nowhere near the traffic of a Tour du Mont Blanc.
Arriving by train: L'Argentière-la-Bessée is the only rail station sitting beside the loop. Joining the route over the Col de la Pousterle adds a walking day in and another out, so 15 days and 223 km in total. The Fournel valley, with its botanical reserve of alpine eryngium, earns that detour.
On top of those itineraries there is one option we took years to schedule ourselves: the rest day. A pause at La Chapelle-en-Valgaudemar or Vallouise, halfway round, changes the character of the second half. Resupply, a night down in the valley, and you set off again on fresh legs.
Under 7 days: take a section, not the loop
In 4 or 5 days the full loop turns into a mountain race. You are better off picking one section and taking the time to walk it properly. The Vallouise to La Chapelle-en-Valgaudemar leg concentrates the wildest side of the tour, with the Aup Martin and the Lac de Vallonpierre: it is the one we chose for our Écrins traverse in 5 days. On the north side, La Grave to Bourg-d'Oisans over the plateau d'Emparis walks in 3 days, with bus links at both ends.
Over a long weekend, a three-day loop in the Valgaudemar or a weekend based in a refuge in the Écrins gives you a real read on the range without booking two weeks off.
Getting to the start: flights, trains and the last bus
One factor weighs almost as much as your elevation budget when you count your days: how you actually reach the foot of the loop.
The useful airports are Grenoble, Lyon, Geneva, Turin and Marseille. From Toronto, Montréal or Vancouver, the realistic pairing is Geneva or Lyon, usually via one European hub. Almost all of it is overnight eastbound, which means landing in the morning after a short night in a seat. Budget a recovery day on arrival rather than trying to reach a valley and start walking the same day. Turin and Marseille work too if the fare or the routing is better.
From the airport it is a TGV or a regional train to Grenoble or Gap, then the local bus into the valley:
Grenoble to Bourg-d'Oisans or La Grave
Briançon to Vallouise or Le Monêtier-les-Bains
Gap to La Chapelle-en-Valgaudemar
Once you are in France there is also the Paris to Briançon night train, which leaves the Gare d'Austerlitz around 21:00 and reaches Gap around 06:50, L'Argentière-les-Écrins around 08:00 and Briançon around 08:30. Two nights in a couchette and no vacation days burnt on travel: an 11-day walk fits into 11 days off rather than 13. L'Argentière-la-Bessée is the only rail station on the loop itself, but the trail does not run through the town, and joining the GR54 over the Col de la Pousterle adds a walking day at each end, which is where the 15-day format comes from.
The GR54 being a loop simplifies everything else: you come back to where you started, with no return transfer to arrange and no rental car stranded on the far side of the range. Pick your starting point to suit your inbound travel rather than the other way around.
Count one travel day on each side when you request time off, plus that recovery day for the time difference. Timetables also move, with engineering work and replacement coaches on some dates, and July and August couchettes sell out early, so check current schedules on SNCF Connect before you lock in your split.
What tends to derail a schedule
Early-season snow patches: some years the Col de l'Aup Martin stays awkward until mid-July. When it is impassable, the variant by the Fournel valley and the Pas de la Cavale reaches the Refuge du Pré de la Chaumette from the other side, at the cost of a very long day out of Vallouise. Refuge wardens know the state of the passes in real time: call them.
Summer thunderstorms: the rule of being over the pass by 13:00 can cut short a stage you had planned as a double. In July and August, a spare day in the schedule is not a luxury.
Full refuges: at the height of summer, bunk availability sometimes dictates the split rather than your fitness. Book early, and earlier still if your dates are locked to a transatlantic flight. The list of accommodation on the GR54 is in our main article on the tour.
Pack weight: fully self-sufficient with tent, stove and food, you slow down noticeably, especially on the technical descents. Compare the two approaches with our bivouac gear list and our article on mountain huts versus gîtes before you fix a number of days.
Walking the Écrins loop with a guide
The number of days also depends on who handles the logistics. On a guided trip the stages are calibrated and the refuges booked before departure. That leaves walking at your own pace:

Frequently asked questions
How many kilometres a day on the GR54?
On a 10-day loop the average settles around 19 km and 1,100 m of elevation gain per day. Over 13 days it drops to 14 to 16 km. Distance stays misleading on this terrain: an 11 km stage crossing the Col de la Vaurze asks more of you than a 20 km valley stage.
How many days for the GR54 with the alpine variants?
The itinerary from La Grave with the alpine variants (Lac de l'Eychauda by the Pas de l'Âne, Pas de l'Olan and Col de Colombes) is published as 14 days, for around 12,500 m of elevation gain. From the station at L'Argentière-la-Bessée, count on 15 days and 223 km, with an extra walking day in each direction over the Col de la Pousterle.
Should you plan a rest day on the Écrins loop?
On formats of 10 days and up, a full or half day off at La Chapelle-en-Valgaudemar or Vallouise often decides how the end of the loop goes. Both villages let you resupply and sleep down in the valley. Flying in from Canada, count that rest day on top of your arrival recovery day rather than instead of it.
Does the GR54 take more days than the Tour du Mont Blanc?
Yes, at comparable distance. The classic TMB is walked in 7 to 10 days where the GR54 runs to 10 to 13: the daily elevation gain is greater and the terrain more technical, with fewer resupply points. The TMB even compresses down to 5 days in its short version, a format with no sustainable equivalent on the GR54. See our full Tour du Mont Blanc article to compare the two loops.
Can the GR54 be done in several trips?
Yes, and it is a good answer when vacation days are short. The loop divides naturally into 3 to 5 day legs between the valleys served by bus: Bourg-d'Oisans, La Grave, Vallouise and La Chapelle-en-Valgaudemar. One summer for the north side, the next for the south. Given the flight, many Canadian hikers instead pair one leg with another range in the same trip.
