Champex-Lac
A small lake village on the Tour du Mont Blanc, with an alpine garden of more than three thousand mountain plants.
Updated 21 October 2026
Champex sits at about fourteen hundred and seventy metres on a shelf above the Val Ferret, with a small lake, chalets round the shore and the Grand Combin visible up the valley. It is best known to walkers as a stage on the Tour du Mont Blanc, which passes through and fills the village with through-hikers from June to September. Above the village the Flore-Alpe botanical garden holds more than three thousand species, subspecies and varieties of mountain plants on a rock-garden site begun in 1925 by the industrialist Jean-Marcel Aubert and open to the public since 1931. A chairlift climbs to La Breya, and paths continue toward the Val d'Arpette and the Fenetre d'Arpette, a demanding TMB variant.
Highlights
- A lake at 1,470 metres - chalets round the shore under the Grand Combin.
- The Flore-Alpe garden - over 3,000 mountain plants, begun in 1925.
- The Tour du Mont Blanc - through-hikers passing all summer.
- The Fenetre d'Arpette - the hard high variant of the TMB above.
When to go
June to September. Half a day, longer if walking.
Things to know
Accommodation books out through the TMB season - plan ahead. The garden is seasonal and closes in autumn. The lake is small and the village compact. Weather on the Arpette route is serious and it holds snow late.
Nearby
Val Ferret runs south-east; Martigny and the Rhone valley are north.
