Mont Mars nature reserve

Parks and reserves  -  Fontainemore

An Alpine environment offering a great wealth of flora and fauna

The Mont Mars nature reserve was established in 1994. It covers 300 hectares and is located at the head of the Pacoulla stream valley. Follow the farm road from the Pillaz hamlet to the Vargno alp to reach the edge of the reserve. Continue following the paved path marked with a black 2 on a round yellow sign: this is the main path, that crosses the entire reserve from West to East and leads to Col de la Balma (2,259 m) and further to the Oropa Sanctuary in the Biella region.

Geology: glacier origin morphology is prevalent, especially the series of terraced rock basins which currently host small lake and marsh basins. Modest remains of the ancient glacier that occupied the valley until 10,000 years ago are found in the snowfield in the small circle at the foot of the North face of Mont Mars. The dominating rocks are mica schist with white marble stripes and dark basic rocks.

Flora: the vast larch forests are dotted with bushy areas (rhododendron, blueberries, juniper). Higher up are discontinuous fields due to the widespread rocky areas where you can find purple gentian, arnica and nigritella. Doronicum austriacum, rare in Valle d’Aosta, can be found among the rocks. Mountain lilium and alpine betony grow on the sunny cliffs. The bottom of the dry fields beautifully contrast with the wetlands in the Leilong basin where floating reeds and aquatic buttercups thrive.

Fauna: the reserve includes species typical of subalpine, alpine and river plains. In the wetlands and lakes you may catch a glimpse of the grass frog, the char, and the white-throated dipper. Alpine fields and prairies are home to the common grass snake, the crow, the rock pipet, the black redstart, the cuckoo, the woodchuck, the chamois, the hare and the fox. The Ptarmigan and the alpine finch (typical of river valleys) are found on Mont Mars’ Northern face. The reserve is a Golden eagle hunting ground.

How to get to the reserve
From Pont-Saint-Martin follow the signs for Gressoney taking the regional road n. 44.
Once in Fontainemore, after about 1 km, turn right crossing the bridge over the Lys stream and go up the left side for 11 km until you reach Pian Coumarial, where you can park your car and continue on foot.

Rock garden

Botanical, geological and naturalistic gardens  -  Fontainemore

The “Le pietre del Lys” (the stones of the Lys) geological trail is situated in Fontainemore, in the valley basin, just a stone’s throw from the town, near the Niana green area.

The feature, which is a didactic trail amid large rocky masses that illustrate the main geological events which took place in the Lys Valley, has both recreational and educational functions, making it suitable for adult visitors and children alike. The sequence of rocks accompanies visitors along a journey in the imagination which, from the Valley of the Dora Baltea river goes as far as the Monte Rosa massif. The lithologies shown belong the the geological systems of the Vallaise: Austrian-Alpine system, Piedmont area, Pennidic system. The masses, of which there are a dozen gathered together in stations, mainly come from detritus deposits, stone quarries, stone landfills and banks of river beds. They come in different sizes (on average volumes in the range of 1 cubic metre) and curious rounded or smoothed shapes due to the fluvial or glacial action or sharp edges, deriving from the quarry extraction or collapses.

Along the trail, visitors will find exhaustive panels featuring the main characteristics of the different rocks.

A playgroud is also present with flying fox, roundabouts, a football field with goals, a drinking fountain and toilets (also for disabled people) and a wide green area with a small lake.

Guillemore Ravine

Lakes / waterfalls  -  Fontainemore

Just outside Fontainemore an ancient mule track leads to ‘Gouffre de Guillemore’, a very deep ravine carved through the rock by the Lys torrent, creating a striking waterfall. The Guillemore ravine combines spectacular scenery with strong roots in century-old history. The area was the only passage for several centuries, in fact the ravine was the meeting point between two mule tracks that ascended the Lys valley on its right and left slopes.
Upstream from the ravine, rocks polished by the glacier can even be seen from the regional road; some potholes are also well visible, being characteristic results of erosion caused by the drilling action of a subglacial torrent loaded with debris. A small perfectly circular pothole is present on the right watershed slope and can be identified with ease since it is often filled with water.
