Description of the route
Take the first section of the regional road SR44 for Gressoney and after about 4 km. turn right and take the direction to Ivéry. Leave your car near the village and take the mule track in the small square with a fountain that goes into a solitary area of pastures and cliffs that converge in the Holay pond nature reserve. In this small wetland there are the common reed and the great bulrush; it is also the only spot known in the Aosta Valley to host the Isolepis setacea and the water purslane. Fauna: interesting, considered the small size of the reserve, the presence, unique in the Aosta Valley, of two rare specimens of amphibians, the dotted Triton and the crested Triton. After crossing the pond and then the road, opposite is the knoll with the ruins of Suzey Castle. Continue towards the locality called Fabiole.
