The Isollaz waterfall is located in the hamlet of Targnod, in Challand-Saint-Victor, in the Aosta Valley. It is considered one of the most beautiful waterfalls in the Aosta Valley for its strength and its grandeur. It’s formed by the Evançon stream that flows through the narrow rock walls and makes a 50-meter jump.
The Evançon stream originates from the streams of Verra and Cortaud, fed by the glaciers of Monte Rosa. Going down to the valley, near the hamlet of Targnod, in Challand-Saint-Victor, it flows narrow between the high rock walls and forms a suggestive waterfall of almost fifty meters.
The area is also of historical interest because it is linked to the ancient mines of Sache: on the left side of the water jet, one of the entrances to this deposit is visible.
Reaching it is very simple as it requires an easy hike on a path, sometimes slightly steep but very short.
The path to the waterfall (20 minutes walk) begins on the municipal road that connects the village of Isollaz to the penultimate hairpin bend downstream of Targnod, hamlet of Challand-Saint-Victor. It is advisable to park in Isollaz, a hamlet that is also worth a visit for its parish church, where you can reach it from the regional road 45 of the Val d'Ayas.
Once parked the car you walk on the municipal road that goes from Isollaz to the S.R. 45, downstream of Targnod, to find after 5 minutes the indication "Isollaz Waterfall" on the left. The path goes down quite steep, with steps in the ground and rock, and can be slippery in case of humidity or after the rain. The descent reaches a widening where you turn left and the path, bordered by a fence, becomes flat and follows the course of the stream. After two benches you get to the view of the waterfall.
