Nature: Nus, Quart, Roisan, Saint-Christophe

This particularly interesting area from a geomorphological and archaeological point of view, the hillock with steep slopes and a flat peak is located to the North-East of Aosta and it is also known locally as “Quota B.P.” (from Baden-Powell, scout founder).

A late Neolithic settlement, dating back to 3000 B.C. was situated at the top of the hill.

The nature reserve extends across 14 hectares at an altitude between 720 - 796 meters and offers typical sceneries of low mountain slopes with southern exposure.
The area is an excellent point for birdwatching during the migratory periods, especially for some birds of prey and corvidae. The reserve is also home to some mammals, reptiles and various invertebrate species.

The area’s climate promotes typically xerophile plant species mainly downy oaks and plants of steppe origin.
This conditions make the reserve’s visit possible all year round, with preference for spring and autumn.

How to get there
From the exit Aosta Est of the A5 motorway, take the national road 26 towards the town. At the second roundabout turn right towards Porossan and go on until the Serod hamlet. Continue following the signs to Saint-Christophe until reaching the little parking at the reserve’s entry.

At the bottom of the central valley, a highly interesting ecological habitat

Location: on the Dora Baltea river, at Brissogne municipality.

The nature reserve extends across 35.4 hectares at an altitude between 526 - 532 meters.
The riparian mid-central valley environment, located in an area formerly occupied by a bend in the Dora Baltea river, is characterised by two quarry lakes with mainly naturally re-populated shores.
The reserve is the most important regional stop over and feeding ground for migratory birds. Many species also nest here. The reserve is home to amphibians, reptiles and, in the lake waters, tenches and pikes.
The vegetation, representative of the ancient riparian landscape now receded from almost the entire valley, is made up of marsh cane, reeds, sedge and a few prominent plants such as the Dwarf bulrush.

How to get there
From Aosta, follow State road 26 towards Turin and turn right at the Brissogne bridge. Go on walking along the Dora Baltea river, until you’ll reach the reserve entry, indicated by an explanatory board.
