2025 Tour du Mont Blanc Trail Updates
Every year, hikers from all over the world flock to the Alps to complete one of the most famous multi-day trails, the Tour du Mont Blanc. It is a challenging journey of physical, mental, and spiritual triumph. We aim to help these adventurers confidently plan and safely navigate their journey around Mont Blanc.
Having access to the latest Tour du Mont Blanc trail updates, including early season snow conditions and route/transport changes, is necessary to be well prepared for the adventure. It helps hikers confirm their gear choice, make any necessary adjustments to their itinerary, and prevent interruptions to their journey.

In 2024, the tunnel connecting Chamonix with Courmayeur was closed from the beginning of September until the December. This was part of a multi-year reconstruction project to refurbish the infrastructure. Although TMB hikers do not need to use the tunnel to complete the trail, some plan to pass through it as part of their logistics to/from the trail and/or to complete a partial section of the trail.
The refurbishment work is expected to continue in 2025, however, no specific dates have been released yet - It should be listed here when it does. You can see this news article on the 2024 closure here too.
New rules introduced in 2023 required those planning to bivouac (wild camp) in French nature reserves around Mont Blanc to ensure they did so in a permitted location and register with the local authorities.

2025 snow Summary
As the 2025 hiking season approaches, it’s important to keep a close eye on latest snow updates!

less-snow-than-average
Unlike 2024, which saw higher-than-average snow accumulation and a cold May that prolonged the snow-melt, the 2025 winter has brought a below-average snowfall across the Mont Blanc massif and there has already been bouts of warm weather. Despite a huge dump of snow in mid April this still remains the view when looking at the long term averages around Mont Blanc. There is always some new snowfall in May which can significantly change the early season hiking conditions so whilst its looking favourable for June hikers, we’ll have to wait and see.

Comparisons to Previous Years
2024: Cold and wet spring kept high and deep snow-pack well into June. Dry trail by 2nd week July.
2023: Moderate snow year, typical melt pattern, some lingering snow into late June.
2022: Low snowpack, early melt, dry trails by mid-June.
2021: Similar to 2024 — heavy late snow and cold spring delayed melt until early July.
2020: COVID-restricted season, but snow conditions were average.
factors for favourable June Hiking Conditions
We’ve been monitoring conditions closely since 2017 and every year it’s a roller coaster. Some look incredibly promising until huge snow dumps at the end of May dramatically changes the picture. Others have resulted in above average snow fall disappearing by early June due to prolonged warm spells in May. While every year is different, these are some of the factors that can lead to favourable June hiking condition;
A smaller snow pack from the winter months that needs to melt away
Freezing level spending an increasing amount of time above the highest elevation points on the trail (~2,500m) during Spring
Limited new snow accumulation during Spring
Plenty of solar radiation hitting the snow from clear sunny days
Snow on the TMB
See the estimated snow depth along the Tour du Mont Blanc in our planning app
The estimated current snow depth and 48 hour snow forecast layers in our planning app are updated daily and inform hikers where snow is expected to be located along their route. This information is provided through our partnership with ExoLab.
CURRENT SNOW DEPTH
Check the snow conditions prior to your hike to understand if there is snow and its expected depth along your route. You can decide to alter your route to an alternative route with no/less snow or skip ahead with transport.
48 HOUR SNOW FORECAST
Understand where and how much snow is expected to fall along the trail for informed hiking decisions.
WEbcams Along TMB
See real-time video footage along the Tour du Mont Blanc
The Tour du Mont Blanc passes through various ski resorts, which have live webcams showing current conditions, including: Les Houches, Courmayeur, La Fouly, Le Tour, Flegere, and Brevent.
📷 LES HOUCHES
This panoramic webcam is installed at Prarion (1850 m), in the Les Houches ski area. It offers a clear view of part of the Tour du Mont Blanc trail that goes through the ski area, Col de Voza and the Bellevue plateau for those taking the cable car and/or alternative route via Col de Tricot. You can also see the town of Les Houches in the valley below and the Bionnassay Glacier on the Mont Blanc Massif.
Tip: If live webcams are only showing black, it’s currently night time at the location. Toggle the clock to yesterday to see latest conditions.
📷 COURMAYEUR
We are lucky to have 3 webcams in this area that shows a considerable amount of the trail in Val Veny. You can click on the little picture in the top right hand corner of the webcam below to see a live video from each of these locations.

Still of camera at start (8th May 2025): Red dots are approx where the Tour du Mont Blanc goes between Col de la Seigne and Rifugio Maison Ville in the Courmayeur ski area. The yellow dots are the alternative route that goes down the valley from the junction near Cabane Combal.
Versante Val Veny (2,032m)
This camera looks into Val Veny and is focused on the area where the Tour du Mont Blanc trail goes in the first few seconds…so pause the video at the beginning! At the start of the video, the camera is pointed up the Val Veny to Col de la Seigne, which is where the boarder with France is in the lowest part of the range. The trail runs down the valley, eventually keeping to the north (right) side. After passing Rifugio Elisabetta, it descends steeply to the valley floor where it follows a track to a junction near Cabane Combal. Here, the main trail rises onto the Val Veny Balcony and reaches a high point of Mont Farve Spur. The immeadiate section coming down from the spur is steep and difficult in snow. The trail continues above the treeline crossing a few bowls before eventually making it’s way into the Courmayeur ski area and the trees. Rifugio Maison Ville can’t be seen through the trees but it is approximately where the red dots end.

TIPS for EARLY-SEASON HIKERS
Even though current conditions are looking promising for early season hiking, anything can happen in the coming weeks. To be prepared, follow these tips:
1) Keep an eye on current snow conditions as we get closer to your departure date
We will be posting regular snow updates to our Tour du Mont Blanc Instagram and Facebook page, including when our team and 2025 ambassadors kick off their Tour du Mont Blanc trips between June and October.
2) BE PREPARED WITH THE CORRECT GEAR
It’s best to assume that early season hikers will require micro spikes and poles to reduce the risk of incidents on difficult snow covered sections, including sloped terrain and steam crossings. Download our recommended gear list here
A special note on ice-axes: We are sometimes asked whether early season hikers should take an ice-axe. Unless you have training and experience with them, our position is no. Completing a section that requires an ice-axe changes the experience from hiking to mountaineering. If you are not an experienced mountaineer, organise a training with a qualified mountain guide and practice your skills on mountains/terrain you are familiar with. Bringing an ice-axe without this experience may give you false confidence to attempt challenging sections that significantly increases the risk of incident. Our advice is to identify the high risk sections and then turn around to avoid them. If you watch our break the trail videos from previous years, we practice what we preach by avoiding high risk snow sections every year. Needless to say, coming home safe is much more important than walking every step on the trail.
3) PRIOR TO DEPARTURE, CHECK SNOW CONDITIONS ON YOUR ROUTE
General snow updates are good, but identifying snow conditions on your planned route is even better. Use current snow depth data in our planning app to check your planned route and determine whether to change your route to a lower/alternative route or to bring gear to match the expected conditions.
Past season updates
Every year since 2017 (with the exception of 2021..😭), we’ve been hiking between Mont Blanc and the Matterhorn during Spring. Since 2019, Brendan, Co-founder of The Hiking Club and our Trail Expert for the Tour du Mont Blanc, has completed a “Break The Trail” journey to provide the first official trail report for the TMB. We share these early-season trail updates for hikers to see what the latest snow conditions look like on the ground, decide on route changes, and finalise gear selection.
