September in Chamonix: What's on and weather

A sense of calm settles over the mountains after the busy summer, and there's a hint of a chill in the air

Imprint: By Tracy Wise, Updated 17 June 2026

One of the best times to visit Chamonix, there's plenty to see and do before autumn arrives.

Whilst the crowds may have dispersed, there is still lots to see and do in Chamonix at this time of year. In fact it's the perfect time to visit. The weather is usually good, and that means there's still plenty of opportunity to get out and about in the valley, unimpeded by the crowds, and it's definitely easier to get a table in a restaurant and a seat on a terrace.

This is when we like to go trail running, hiking, biking, and climbing, but without the crowds. Plus there's always time for some relaxation when you come to Chamonix.

Read on for a look at what we like to do in resort throughout September.

September events in Chamonix

Just because the UTMB is over, doesn't mean there are no trails to be run. The TAR is a prestigious trail running race in the Chamonix valley that gives athletes some of the most iconic and fantastic views of Mont Blanc. Starting from the town of Chamonix, the route climbs high up into the Aiguille Rouges nature reserve, taking a different path each year. Not for the faint-hearted (or the unprepared), the race covers a distance of 54km and a total ascent of over 4,000m. Top runners can complete this race in around 6.5h but, for many, it will mean a long day of running lasting between 10 to 13 hours. If you don't want to take part, then supporting the event and watching along the way can be just as fun.
