Plan this trip
Each site opens on its own search: choose your dates there. A few open on their home page, where you type the place too.

Travel insurance
Check whether your bank card or home insurance already covers this trip.
If the trip needs a visa, the travel agent or visa centre usually sells the cover it asks for.
Mobile data (eSIM)
Your own plan's EU roaming may already cover this.
Renting a pocket Wi-Fi is the other common way to stay connected.
These are sites people in book with. Each opens in a new tab, on the site's own pages.

Ten-year averages for this calendar month. 15 rainy days, as the weather station at Col du Grand St. Bernard (24 km away) counts them: its May average over 10 years, 2017–2026 (WMO 06717). A rainy day is one with at least 1 mm of rain.
Weather read at Chamonix town: ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.
