From Villar-Loubière to La-Chapelle-en-Valgaudemar

 Apollos, azure, fritillary, black-veined white, or marbled white...The slopes heated by the sun, flowers that are filled with nectar, everything is in place to attract a cohort of butterflies and other insects on the slopes that lead to the Souffles refuge

From the refuge, or during the climb, a peculiar geological formation may catch your eye on the opposite bank, above the old hamlet of Peines. Sedimentary rocks are trapped in the middle of crystalline formations where erosion has created a specific pattern of erosion that looks like a giant tiger has clawed at the rock. This morphology is what gave it the name Arraches.

During your walk, you might come across sheep on the mountain pastures. This is an old form of pastoralism, as proven by the dry stone enclosures that you will see. These are known as 'jas'. You will also notice a rock shelter near to the Clot. The sheep that are in these pastures belong to breeders from the valley or from the Bas Champsaur area.

The upper limit of the forest is where you are likely to see the black grouse. The female has faith in her bland-coloured feathering that camouflages her in the vegetation, making her difficult to spot. On the other hand, the male, which is black and white with red "eyebrows”, is not so private, particularly during the reproduction season when their cooing and hissing sounds echo in the mountain in the early morning.

This walk is a summary of south facing slopes in the Valgaudemar area. It starts in the warm scree that it more or less vegetated. It then progresses over lawns and moors of juniper, blueberries or bearberries... They give way to mountain ash, whitebeam and amelanchiers indicating that the forest will soon take over. Higher up, the beech forest casts shade on the walkers, next a beautiful larch forest is a sign that the forest environment will give way to the high altitude moors and lawns. The Lautier lake and the surrounding ponds are a haven for aquatic species. Still higher, is the realm of rocks and chamois.

There is a large variety of plant life along the itinerary, particularly on the slopes above the refuge, due to the exposure, the soil types and the altitude. Marjoram, lis, laserwort, houseleek, stinecrop, gentian, columbine, aconite and many others are present.

The Souffles mountain refuge is managed by the CAF (French Alpine Club).  A keeper is present from June to September. Here you have the opportunity to get something to eat whilst chatting with a mountain professional or spend a night at high altitude if you prefer. This is a good way to split the itinerary in two.

The view over the valley as seen from the Souffles refuge is well worth the trip. Along the crossing from the Clochettes pass to the Colombe pass, there are numerous viewpoints that give multiple variations on a single theme: that of a high mountain valley.

At high altitude, it is possible to see two amphibian species. These are the common frog and the alpine newt. The latter is rarer. It is a fragile species and consequently a protected one. When adult, it resembles a small lizard. In its aquatic cycle, the male has an orange colour on its belly and throat. Most of the time when we watch it in the lake, it is motionless with its feet spread out, as though it were weightless. If it is frightened, a swift movement of the tail and it will find refuge under a stone. The lake is used for rearing which is not a good thing for newts that are food to fish. On the other hand, the ponds that are situated above the lake do not have fish and the alpine newts are at home and reproduce there.

This is a remarkable site. Brown trout are reared here for the delight of anglers.

The rock partridge likes rocks and open moors where the young can feed on the insects that are necessary for their growth. It is not rare to see a group towards the Lautier lake or the Colombe pass.

The golden eagle can be seen all year round in the area that they have chosen for their home. In the summer, it is not rare to see griffon vultures gliding above the pastures in search of corpses. On the other hand, it is rare to spot the bearded vulture. This vulture that lives on bones is being reintroduced to the Alps. The Vercors is the nearest place where they are being released.

A silhouette that stands out on a ridge, a worried whistling sound or bustling in the shingle...there are numerous opportunities to see this animal that is emblematic of the mountain.

Since the end of the ice age, water has carved the rock and the passage of materials has created a small gorge polishing the base rock (gneiss, micaschists). The National Park has taken on the challenge of building a wooden walkway for walkers to cross this gorge. 

Over a change in altitude of a hundred metres there is a covering of heather which provides pollen for the bees and purple colour in Autumn, A small persistent shrub with tiny leaves and little pink flowers, it is called Common Heather or False Heather.

At the beginning of the path, is a big waterfall that you can approach on a narrow footpath just before climbing the coast. Situated on Combefroide torrent at a rocky escarpment, this waterfall has several projections and presents a total drop of several dozen metres.
