The waterfall is among the most beautiful in the Aosta Valley, hidden in a rocky gorge of the Ayas Valley

The Evançon stream originates from the streams fed by the glaciers of Monte Rosa. It flows down to the valley, near the hamlet of Targnod, in Challand-Saint-Victor, squeezed between the high rock walls, and it forms a picturesque waterfall with a drop of almost fifty meters.

The area is also of historical interest as it is linked to the ancient mines of Sache: one of the entrances to this field is visible on the side to the left of the jet of water.

The path to the waterfall (20 minutes’ walk) starts from the municipal road that connects the village of Isollaz to the penultimate bend downstream of Targnod, a hamlet of Challand-Saint-Victor. It is advisable to park in Isollaz, a hamlet which, in itself deserves a visit also for its parish church, and you can get to it from regional road 45 of the Val d’Ayas.
Once you have parked your car, walk along the municipal road that goes from Isollaz towards S.R. 45 downstream from Targnod for about 5 minutes, until you reach the sign “Cascata di Isollaz” on the left. The path goes down quite a steep incline, with steps carved out in soil and rock, and so they can be slippery if it is humid or after it has rained. The descent reaches a clearing where you turn left and the path, flanked by a fence, becomes flat and follows the course of the stream. After passing two benches you arrive at the astonishing view of the waterfall.
