ABOUT THIS ROUTE
The route in detail
The road to Cogne is the Aosta valley's great dead-end ride: forty minutes of narrow gorge climbing from Pont-Saint-Martin at the valley floor to the national park village at 1,500 m, where the Gran Paradiso massif — Italy's oldest national park, created to save the ibex — fills the horizon. The village is the trailhead for the park's most accessible walks, including the waterfall gorge above Gimillan.
From Aosta the SS26 runs down the main valley to Pont-Saint-Martin, the Roman-arched gateway to the Cogne valley. The regional road turns south and climbs the gorge of the Grand Eyvia river — single-lane sections through the rock walls, tunnels and village hamlets — opening at Acceglio country and rising past Valnontey to Cogne. The village meadows end at the park trails: the Gimillan waterfall walk and the ibex-viewing slopes above the tree line. Return the same gorge road with the evening light on the valley walls.
