Three months worth booking
The same year of measurements, decided rather than tabulated. Each opens the map below on dates in that month.
Staying there
A hotel room in France emits about 6.7 kg CO₂e per night under UK Government 2026 factors — a country average per occupied room, not this or any particular hotel. 7 nights in one room adds roughly 47 kg — about 6.0× the carbon of one person getting there by rail from Milan. Two sharing the room halve that share each; the journey does not halve.
How busy it gets
Hautes-Alpes records 31.9 overnight stays per resident a year (4,621,377 nights in 2025). That is heavy tourist pressure — among the densest in Europe.
Eurostat, nights spent at tourist accommodation by NUTS 3 region, against resident population. Shown for context only — it plays no part in which destinations appear or in what order. Eurostat does not cover the United Kingdom after 2016, nor North Africa or the Levant at all, so this figure is absent for roughly a third of the destinations here.
