A road cyclist on a mountain road in summer

Road cycling in Valais: climbs to dams and passes

Two climbs start 28 minutes below, in Sion, and a third finishes in Thyon 2000, above Les Collons. Back at the house: the terrace hot tub and the sauna.

Three climbs with numbers

Sion to Grande Dixence: 26.6 km, 1,650 m of climbing, 6.2% on average, 10% at most, finishing at 2,141 m. In 2026 the dam road opened on 4 June; it is closed in winter.

Thyon 2000: about 20.5 km at about 7.7% (a media source, not the operator). Martigny to the Great St Bernard: 42.1 km and 2,046 m of climbing; bring a light for the galleries.

How the planner sets out a cyclist’s week

A hard day alternates with an easy one: after a climb, the spa or a lake by car. Never two climbs in a row.
