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, Tour du Mont Blanc. It is a challenging journey of physical, mental and spiritual triumph. Our mission is to help these adventurers confidently plan and safely navigate their journey around Mont Blanc.
One of the core pieces of information that gives hikers the confidence to complete their trip is having access to the latest Tour du Mont Blanc trail updates, including snow conditions, route detours, and general trail conditions. It helps hikers prepare the right gear, select the right route, and be aware of any trail updates that might impact their itinerary.
For the past 6 years, The Hiking Club has been sharing the most up-to-date Tour du Mont Blanc trail conditions.
2025 snow update
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.
See WEbcams along the trail
The Tour du Mont Blanc passes through various ski resorts. Most have webcams which we have embedded below. For areas of the trail without webcams, the current snow depth layer in our planning app provides a current view of expected conditions
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.
No up to date webcams in this area pointing towards the trail. Below is an image of the estimated snow depth shown in our planning app at the date referenced below.

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 huge snow dumps at the end of May dramatically changes the picture. Others have resulted in above average snow fall turning to wild flower meadows early with prolonged warm spells in May. While every year is different, these are some of the factors that can lead to favourable June hiking conditions on the Tour du Mont Blanc;
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
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.
