Good news for mountain lovers: the numbers confirm the summer momentum. With an occupancy rate around 65%, an increase of +5.5% compared to last year, the mountain is gaining ground. From the Pyrenees (+4%) to the Southern Alps (+5%) and the Northern Alps (+6%), the peak occurred in August, boosted by the heatwave and the extended weekend of August 15. Between welcome freshness and numerous activities, the altitude stands out as the beautiful escape of the summer.
As of September 4, 2025, at 3:43 PM, the verdict is clear: the mountain has had a champion summer. With an occupancy rate rising to about 65% (+5.5% year-on-year), peaks recorded in August driven by the heatwave and the extended weekend of August 15, and a visible progression in all ranges, the season confirms a genuine shift in desires. Supported by the ANMSM and the multi-seasonal barometer of Atout France, the trend fits into a context where purchasing power is challenged and where the coast remains dominant (around 70% of summer visitors), but where altitude gains points thanks to freshness, a mix of activities, and the desire for disconnection.
In a contrasting summer for tourism, the mountain destination has continued its evolution into a reliable asset. Despite a backdrop marked by declining purchasing power and tight choices, accommodation occupancy rose to around 65% over the entire season, representing an estimated gain of +5.5% compared to 2024. A sign that altitude meets current expectations: breathing fresher air, spending smarter, doing a lot… all while truly resting.
Figures that rise like a ski lift
The movement is not a flash in the pan: the progression is observed throughout the summer period, with better dynamics than last year and a soaring month of August. Between long sequences of heat and the bridge of August 15, attendance literally climbed to the peaks. This validates the signals sent out as early as July by the multi-seasonal barometer of Atout France: more and more French people are aiming for high altitudes for their summer stays.
Mapping the ranges: the winning alignment
Another strong sign: the growth is widespread. From the Pyrenees to the Southern Alps to the Northern Alps, the trend is upwards, with progress of a few points depending on the ranges. The resorts confirm a continuous rise over several years, as noted by the ANMSM. This is not a spectacular leap, but a further step on a sustainably upward trajectory.
Mountain versus coast: summer duel
In the holiday ring, the coast retains the belt: it still captures around 70% of summer stays. But the mountain is nibbling at its share of desires, and the 2025 season confirms this. In a context where some coastal areas show occasional fatigue, contrasting signals are multiplying: for example, there was a decline in attendance in the Basque Country or a decline in nautical tourism in Balagne. Nothing homogeneous, but enough indicators to understand why fresh valleys and quiet alpine pastures are appealing more than ever.
Why is it so appealing? Freshness, activities, and disconnection
The secret to the recipe? A well-balanced cocktail. In summer, more than one in two visitors opts for physical activities: hiking, mountain biking, trail running, via ferrata. But the program doesn’t stop there: pools, creative workshops, heritage, and local dining are fully booked. At the same time, the desire for disconnection is evident… even on social media, a delicious paradox: there, one boasts about the art of leaving one’s smartphone at the bottom of the bag, just after posting the panorama of the day.
The weather factor plays a key role: when the heatwave engulfs the plains and the South, altitude offers milder temperatures, restorative sleep, and the possibility to move at any hour. Destinations have refined their offerings to align with the desires of each group: families, couples, groups of friends, contemplative solo travelers… everyone finds the right trail for them.
Responsible mountains: ecogestures at the top
The rise in strength is accompanied by a growing concern for sustainability. Hosts and offices strengthen their initiatives around gentle mobility, energy efficiency, and proper behaviors in nature. A concrete example: learning to manage one’s waste during a night under the stars.

The bike route as a bridge to altitude
Another trend that’s gaining momentum: bike tourism. By linking valleys, passes, and major national routes, the Alpine and Pyrenean territories are riding the wave of spectacular bike routes in France. The result: hybrid stays, where one alternates between pedaling, taking the lift for mountain biking, and enjoying delicious descents in the village. An ideal playground for both short breaks and longer itineraries.
Access and flow: from the sky to the valleys
The pressure on transport is also shaping the season. Between reinforced rail lines and fluctuating air traffic, flows are being reorganized. The aeronautical trends and airport attendance set the tone for long-distance arrivals, while nearby clientele prefers car sharing or the train when possible. The outcome: shorter but denser stays, and a strong desire to “do everything on foot” once there.
The calendar effect: August 15 as turbo
The calendar is not just a detail: it can swing a season. The August 15 bridge served as a springboard for attendance, especially since it coincided with a period of lasting heat. Resorts that managed to create events right at this time (festivals, markets at altitude, wellness nights) played their cards right, while smoothing demand in the adjacent weeks with flexible offers and dynamic pricing.
Tailored offers: the mastered stretch
Success also lies in the resorts’ ability to create a “menu” that’s “à la carte.” Some want sensations, others want contemplative breaks; plans might include a pottery workshop in the morning, a hiking loop in the afternoon, and a Nordic bath in the evening. This versatility attracts diverse clientele and retains those who, in winter, no longer ski as much. In the same spirit, the mediation around heritage and local products enriches memorable experiences at a controlled budget.
Heading towards a 4-season mountain
In the face of a more uncertain future regarding snow, professionals are accelerating diversification. The goal: to increase revenue by extending demand into spring and autumn, focusing on health, sports, culture, and nature. The figures from this summer, increasing for the sixth consecutive year, validate this strategy: the mountain is no longer just a refuge from the heatwave; it is a fully-fledged summer destination, clear, accessible, and inspiring.
