  Flora

  The field maple

  This is the smallest member of the family of forest maples, growing to a height of 8 to 15 metres. It can live for up to 150 years. Its leaves have five round lobes; they are winged with wings sticking out in opposite directions. It is not fussy as to the dampness of the soil and it can withstand cold temperatures and drought. It is also an excellent bee forage plant, which can be enhanced by the proximity of a hive.

  Fauna

  The marmot

  In the alpine pastures, the iconic marmot utters a loud high-pitched whistle to warn its neighbours of approaching danger: the golden eagle is on the prowl! This medium-sized rodent prefers to live in the high-mountain grasslands in family groups. Their favourite pastimes are gnawing, digging, taking a siesta in the sunshine and performing somersaults. In the winter, the marmot takes refuge in its burrow where it hibernates. It is only seen between the months of April and October. It marks the boundary of its territory by rubbing its cheeks on the rocks or leaving droppings.

  Flora

  The woolly berardia

  The woolly berardia is a plant that grows approximately 10 centimetres tall and has a short, almost non-existent stem. This perennial member of the Asteracea family grows in limestone and schist screes. It has veined oval, woolly leaves which are covered in soft hairs. Its 4 to 7 cm compact head with pale yellow flowers stands up from its centre.

  Flora

  The common rock thrush

  In May, a melodious song rings out from the cliff top. It’s the song of the common rock thrush, appropriately named and a wonderful bird. Although the female is rather dull (an advantage when egg-sitting) the male sports an orange underside and a blue-grey head. A trans-Saharan migratory bird, every year it returns to the mountains of Southern Europe where it frequents the rocky, sunlit slopes. It is not very common and is in decline, so spotting it is even more special!

  The Cabane de Chouvet

  Discover one of the most famous forest cabins in the Vallouise valley, the Cabane de Chouvet. Surrounded by larches, Scots pines and black pines, this unmanned cabin stands at an altitude of 1,860 metres. On this slope, the mountain land has been under restoration since 1914 to prevent erosion and to combat deforestation.

  Flora

  The Briançon plum tree

  Not far from the Cabane de Chouvet, some small trees grow which are covered in white flowers in the springtime. This is the Briançon plum tree. Later in the year, it will produce golden plums with a tart flavour, carried on a very short stalk. A species endemic to the southwestern Alps, it has been prized by man because the kernel inside its stone produced a very fine oil, called huile de marmotte (marmot oil).

  History

  Les Choulières

  The French children's song Savez-vous planter les choux? (Do you know how to plant cabbage?) is very appropriate here! In any event, the name Choulières is believed to be a reference to a place planted with cabbages and, by extension, a place where vegetables are grown. The phasing out of crop cultivation in the mountains has altered the landscape: the hay meadows and fields are now used as grazing meadows for increasingly large flocks of sheep.

  Ailefroide

  Formerly an alpine pasture hamlet, Ailefroide lies at the foot of Mont Pelvoux, surrounded by larch woods and granite cliffs. It is the last hamlet in the valley, at the confluence of the valleys of Saint-Pierre and Celse Nière. The name Ailefroide is thought to originate from the term Alpe froide or “cold Alp”, a reference to the lack of sun here in the winter. It is the starting point of numerous trails and is a paradise for climbers. Ailefroide is a legendary destination for mountaineers: a stele commemorates the conquest of Mont Pelvoux in 1828.

  Fauna

  The golden eagle

  A pair of eagles lives in the Ailefroide valley. Every pair has a very large hunting territory, which means there can be no more than one pair in a small valley of this size. This pair has built several eyries in the cliff walls around Ailefroide: just one is occupied every year, after a few refurbishments. The eyries are located at the lower altitudes of the hunting territory, so that the eagles can easily bring heavy prey back to the eaglet.

  The penstock pipe

  This penstock pipe carries water to the Le Claux hydroelectric power plant, located just below here, which exploits the water from the Les Écrins massif. The power plant was inaugurated in 1932. At the time, the electricity generated was primarily used to power the aluminium factory located in L'Argentière-La Bessée.

  Flora

  Cool meadow

  The track passes through a meadow area, which is categorised as "cool" because of the ground water content there. A botanist quickly recognises this type of meadow through its range of plant life and, in particular, the presence of bistort, a bottle brush-shaped plant bearing a dense spike of tiny pink flowers at the top of its stem. It is also called langue de boeuf ("ox tongue" in English) because of the shape of its leaves.

  Flora

  The grey alder

  In the valleys of the Alps and the Jura, the grey alder often grows in place of the black alder, present in many parts of France. Like its cousin, it grows on riversides and plays an important role in stabilising the banks. If it is cut down, its wood is bright orange in colour. But why cut it down?

  Water

  The Gyr

  Humans are decidedly bizarre animals: they build, knock down and start again. To protect the new infrastructures of Pelvoux, the Gyr was dammed. But, not able to flow as it did before, it deepened its bed, thus placing the foundations in danger of damage. And so works were carried out to widen its bed, allowing it to flow more naturally. This is also more favourable for biodiversity, as well as protecting the developed urban areas.

  The ski resort of Pelvoux-Vallouise

  The route first leads through the small ski resort of Pelvoux-Vallouise, built in 1982. Very family-focused, in winter it's the ideal place for young children to learn to ski, with small lifts lower down, while their big brothers and sisters can ski higher up.

  Flora

  Silver spike grass

  A grass grows in large clumps on the embankment: silver spike grass. It is adapted to stony, dry and sunny ground. Its inflorescences reflecting silvery-gold glints create a beautiful effect, but they are particularly noticeable in the late summer, when it forms large shimmering bouquets in the evening sunlight.

  Flora

  Forest of pine and oak

  The path now alternates between cleared areas and forested areas. This forest contains Scots pine (recognisable by its orangey coloured trunk, especially at the top), downy oak (its young branches and leaf undersides covered with a fine down), and larch. The Scots pine and downy oak are very drought-tolerant (it is very limey soil here) and can also withstand low temperatures, and they are typical of the montane zone in this part of the Alps.

  Architecture

  Saint-Étienne de Vallouise Church

  Listed and protected as an historic monument since 22 October 1913, the church dedicated to Saint Stephen is one of the most beautiful religious edifices in Hautes-Alpes. It is typical of the Romanesque churches in the Briançon region built in the second half of the 15th century, although its exact construction date is still uncertain.

  Panorama

  The Montbrison massif

  The path offers a beautiful overall view of the limestone massif of Montbrison, overlooking the hamlets of Pelvoux with the peaks of the Cime de la Condamine, the Tête des Lauzières, the Pic de Montbrison and the Tête d'Amont.

  Flora

  The narrow-leaved lavender

  The path crosses some limestone screes. It is a dry environment. The narrow-leaved lavender grows in sunny areas, a reminder that the Pays de Écrins is in the Southern Alps after all! Not to be confused with the lavandin, this plant naturally grows on rocky slopes in the mountains of the Midi.
