French mountain resorts saw a significant increase in occupancy during the summer season from July 4 to August 22, 2026. The overall occupancy rate reached 65.8%, up 2.5% from the summer of 2025 and 5% from 2024. July contributed the most, with an occupancy rate of 63.3%, up 3.6%, while August reached 72%, up 1.1%. The peak period was during the week of August 8, with an 80.7% occupancy rate. The Pyrenees led with 69.8% occupancy, outperforming the Southern Alps (66.8%) and the Northern Alps (64.6%). Tourism residences and hotels maintained steady levels, while vacation villages and real estate agencies saw the strongest growth. Most visitors were French, making up 81.7% of the clientele. The summer season was influenced by a record-breaking heatwave in June, which saw 72 departments under red heatwave alerts, the highest number since 2004. A 23-day heatwave from July 28 to August 19 matched the record set in 1983. This extreme heat in the lowlands pushed more people to seek relief in the mountains. For the 2025 summer season, the coastline saw 104.6 million overnight stays in collective accommodations, compared to 44.6 million in mountain regions. Both areas experienced similar growth rates, with the coast rising by 2.7% and the mountains by 2.5%. This trend continued in 2026, with Brittany reaching 84.8% occupancy in August and the Normandy coast exceeding 90%, showing the strongest increase among all French coasts. In Austria, the 2026 summer season saw 41.87 million overnight stays, the highest since 1973. Alpenverein huts recorded about 20% more overnight stays in July compared to the previous year. In Italy, the province of Bolzano saw a 5.9% increase in arrivals in July, and the JFC Observatory estimated 79 million overnight stays for the Italian mountain season, up 5.8%. In Switzerland, lifts recorded 7% more first entries from May to the end of July, and 29% more than the five-year average. While many operators in mountain villages and vacation clubs reported positive results, there were notable differences depending on the destination. MMV, a specialist in mountain clubs, reported a 5% increase in revenue and an average occupancy rate of 83% in July and August. Belambra announced a 7% increase in revenue and a 4.5% increase in customers, welcoming 150,000 vacationers. In contrast, tourism residences monitored by the FNRT (including Pierre & Vacances, Goélia, and Odalys) had an occupancy rate of 52.6% for the season, down 1.2 points compared to 2025. Vacationers were increasingly choosing short stays and making last-minute bookings due to the heat. At MMV, the share of short stays increased by 10 points, with more reservations made less than ten days before arrival. VVF noted an acceleration in short stays, while Odalys recorded a three-point increase in revenue from such stays. Belambra recorded 60 last-minute reservations for arrivals on the same day by the end of July. The trend of last-minute bookings became more visible, with Vacances Bleues noting temporary sales stops due to heatwaves before rapid resumptions toward more climate-adapted destinations. Purchasing power also influenced vacation choices, with an estimated 8% decrease in the customer base for budget rentals. For households with more financial flexibility, stays remained similar but with more integrated services to better manage costs. The Mediterranean remained the top destination, accounting for 56% of summer revenue, while the mountains, which were 30 to 40% cheaper on certain destinations, attracted budget-conscious travelers. September saw an increase in fragmented, itinerant travel, with French vacationers visiting two or three destinations during the same summer. The off-season became more of a period of deferral, especially for those who could choose their travel dates more freely. At Odalys, mountain stays increased by 28% in September, while the FNRT observed a slight increase in coastal stays and a rise of about 1.5 points in mountain occupancy rates for the month. Some senior travelers shifted their stays from June to September, with Vacances Bleues noting a strong acceleration in September sales since the end of August.
