Become a partnerThe Col de l'Iseran links Val-d'Isère, in the Tarentaise, to Bonneval-sur-Arc, in the Maurienne. It is the only road crossing inside the Parc national de la Vanoise. Its altitude is given as 2,770 m or 2,764 m depending on the page — including within one official site.

The Col de l'Iseran crosses the divide between the Isère valley, in the Tarentaise, and the Arc valley, in the Maurienne, between Val-d'Isère (73150) and Bonneval-sur-Arc (73480). The road over it is written D902 by the Val d'Isère tourist office and in the col's postal address, RD 902 by the Département de la Savoie.
Its altitude is not settled: 2,770 m on some pages, 2,764 m on others — including on two pages of the same tourist office. We do not pick a winner. The chapelle Notre-Dame-de-Toute-Prudence, built in 1938-1939 by the architect Maurice Novarina and inaugurated on 20 August 1939, sits at 2,769 m per the Mérimée heritage database: a third point again.
This is the only road crossing inside the Parc national de la Vanoise. The direct consequence for visitors with a dog: dogs on a lead are accepted on the col car park only, and the national park bans dogs from the park core even on a lead or carried, with a €135 fine.
On the D902 from Val-d'Isère to the north or Bonneval-sur-Arc to the south. The road is closed in winter; opening and closing dates are decided by the Département de la Savoie and published live on savoie-route.fr.
