With breathtaking landscapes, charming alpine villages, and challenging mountain passes, TMB is a dream destination for trekkers.
Whether you’re an experienced hiker or a beginner looking for an adventure, this guide will cover everything you need to know about the Tour du Mont Blanc, including the best time to go, route options, essential gear, and top highlights along the way.
What is the Tour du Mont Blanc?
The Tour du Mont Blanc is a multi-day trekking route that takes hikers around Mont Blanc (4,809 meters / 15,777 feet), the highest mountain in Western Europe. Unlike a summit climb, this trek allows adventurers to experience the beauty of the Alps without technical mountaineering skills.
The trail passes through stunning glaciers, alpine meadows, and deep valleys, offering breathtaking views at every turn. Along the way, hikers stay in mountain refuges, small hotels, or campgrounds, making it a comfortable yet adventurous journey.
Best Time to Hike the Tour du Mont Blanc
The ideal time to hike TMB is between mid-June and mid-September when the weather is most stable.
-
June – Early July: Snow may still be present at higher altitudes, but the trails are less crowded.
-
Mid-July – August: Peak season with warmer temperatures and fully open refuges, but also the busiest time.
-
September: Cooler weather and fewer crowds, but some accommodations may start closing for the season.
For those seeking a quieter experience, early June or September are the best options.
