Route des Grandes Alpes
France, 829km
This route offers more than 800km of incredible mountain riding crossing the French Alps from north to south, from Thonon-les-Bains on the shores of Lake Geneva to Menton on the Mediterranean. It carves its way through sleepy villages from the high peaks of the Northern Alps and Mont Blanc, to the turquoise waters of the Côte d’Azurvia the Southern Alps – some of the most spectacular landscapes in Europe.
The route joins together 15 mountain passes, including the most famous cols of the Tour de France: Col de la Cayolle, Col de Valberg and Europe’s highest, the 2,764m Col de l’Iseran.
Riding high
Accept the challenge of riding the Col de la Bonnette up to the monument at Cime de la Bonette – at 2,802m, it’s the highest non-dead-end road in Europe.
Col with a view
From the Col de la Colombière (1,613 metres) pass through La Clusaz to arrive at the Col des Aravis (1,486 metres). This pass provides a magnificent view of the entire chain of the Mont Blanc massif.
