Lac Blanc Hike: Col des Montets to Lac Blanc, Chamonix
Is the Col des Montets to Lac Blanc Hike One of the Best Hikes in Chamonix?
The payoff is extraordinary: alpine ibex, glacial viewpoints, the mirror-like Lac de Chéserys, and finally Lac Blanc at 2,352 m (7,717 ft) with the full Mont Blanc massif reflected in the water.

Sometimes in life, the best comes last. Serendipitously, this proved true on our very last hike of our intergenerational do-it-yourself Tour de Mont Blanc (TMB) (opens in new tab). After ten glorious days of hiking the TMB – from the stunning Val Ferret(opens in new tab) and Val Vény in Courmayeur(opens in new tab) to our hike above the gorgeous Champex-Lac in Switzerland(opens in new tab) and finally to a variety of different hikes in Chamonix-(opens in new tab) our hike to Lac Blanc proved to be the one hike that had us wondering when on earth we’d ever be able to come back to this magical place. The hike to Lac Blanc reminded me exactly why I hike in the first place: To feel utterly, insanely alive. And, there is nowhere I feel more alive than outside. The pure, raw beauty of the Alps and the Tour de Mont Blanc itself can all be captured in this one hike. It is a must-do for anyone in Chamonix and anyone hiking the TMB.
We had heard about Lac Blanc from our hotel and had desperately wanted to hike there earlier but the gondola lift to La Flégère was closed. So instead, we filled our first two days with a hike to the top of Le Brévent that affords stunning panoramic views of Mont Blanc,(opens in new tab) and we did an incredible hike along the Grand Balcon on Mont Blanc to the Mer de Glace.(opens in new tab) While both hikes are exceptionally stunning for some reason I had to see Lac Blanc. I had this nagging, unexplainable urge to do this hike so I persisted. Our hotel manager told us we could reach Lac Blanc a different way – albeit a bit longer of a hike – if we drove past Argentière and parked at the Col des Montets located in the Réserve naturelle des Aiguilles-Rouges. It was rated a difficult hike but was doable in anywhere from 4-7 hours depending on level of fitness. I got my dad and son to agree and on our last day in Chamonix we set off for what would be the greatest hike of the entire trip.
We arrived at the trailhead shortly after ten. There were plenty of parking spots remaining, which was of course a good sign that this beloved hike was not too busy yet. It was an absolutely perfect day for hiking, with a few scattered powderpuff clouds, brilliant sun, and a glorious blue sky. We could not have asked for a better day for our last hike.
Trail at a Glance: Col des Montets to Lac Blanc
Before you lace up your boots, here is what you need to know about this route.
This route is the alternative to the La Flégère gondola approach. If the gondola is running, you can also access Lac Blanc from the La Flégère lift station and hike along the Grand Balcon Sud. The Col des Montets start adds distance and elevation gain but rewards you with a quieter, wilder approach through the heart of the Aiguilles-Rouges nature reserve.
