Departure : Hameau de Caleyère, Embrun

From this emblematic summit (2552 m), the view of the Embrunais and Serre-Ponçon lake is magnificent. A small chapel bears witness to the pilgrimage which takes place every year.

Overhanging the town of Embrun which is less than 5 km away, the Mont Guillaume is particularly important for its inhabitants.  Seyères chapel has been completely restored, and at the beginning of July it welcomes a mass dedicated to Saint Guillaume which lends an extra dimension to this hike.

At the carpark, take the forest road for 50 metres and skew to the right on the Widman track. Join the path. On the first bend to the right, ignore the path on the left and go up the track (Séyères chapel, mont Guillaume by Pré-Clos). Leave the path at the fourth bend to take the track to the left (Séyères chapel, mont Guillaume on the Widman track). Ignore the first path that goes down to the right, then another facing that climb up to the crossing. Take the path on the left until Séyères chapel 200 m away (fountain, picnic area). Continue along the same path and take the track to the right (Mont Guillaume on the Widman track) at the fork. At the first bend (cairn), climb the track to the Saint Guillaume chapel (2542 m), then to Mont Guillaume. Return using the same itinerary.

Pastoralism
Woodland grazing

The Embrun communal forest reconciles forestry and pastoral objectives. This 646 ha larch forest consists of a light wood enabling the growth of forage crops. 1200 sheep and 150 cows graze in one of the most beautiful larch forests in the Hautes-Alpes. This forest which protects the lower slopes from avalanches, from mud slides and from falling stones is a lovely example of a multifunctional forest where the production of wood for timber or for heating, coexists with grazing and for the general appreciation of the public.

History
The Widman track

On the 12th February 1897, wanting to show that skiing was faster across the snow than crossing it with the snow shoes then provided to the mountain troops, Charles Eric Widman, lieutenant in the 28th Alpine battalion at Embrun, undertook the ascent of Mont Guillaume. He left at 5 o’clock from the station and reached the summit at 10h30, after having climbed an elevation of 1681m. He carried out the first ascent on skis in the French Alps. On the one hundredth anniversary of this exploit, this itinerary was named the « Widman Track».

Flora
Dyer’s Woad

Punctuating the edges of the paths, this green and blue-green biennial, is also known as « Saint Philippe’s herb ». A large robust plant topped with a parasol of yellow flowers, it has many uses. While its leaves provide a blue dye used to colour clothes, façades and carts (the famous « blue cart » which had the virtue of repelling flies), its roots are used against the mumps, infectious hepatitis, sore throat or the fever.

Flora
Globe Orchid

In the orchid family, the Globe Orchid needs a lot of light to develop and can often be seen in the meadows. Its leaves are all on the stalk which ends in a globular inflorescence with many small flowers. These form a dense spherical spike. They possess a short spur, external sepals which are well spaced, and a speckled tri-lobed labellum.

Fauna
Roe Deer

Hidden in the larch forest, the Roe Deer sometimes shows its fine head at dawn or at dusk. Not always easy to see this discreet animal but a few tracks or droppings can give its presence away.: the heart shaped print of its delicate hooves, the trunks of shrubs nicked by young fallow deer rubbing new antlers there to remove the last shreds of velvet, the ground scratched by the young male to mark his territory during the rutting season. Sometimes it is a deep sonorous and guttural bark that resonates in the woods.

Flora
Pale Orchid

A perennial plant 10 to 30 cm high, the pale orchid likes the edge of forests and the alpine meadows (400 to 2400 m), and slightly acidic chalky terrain. It is easily recognizable thanks to its pale yellow flowers which extend in to a long upstanding spur. This robust plant, with large green oblong shaped leaves, has an elderberry scent.

History
Séyères Chapel

Rebuilt in 1859 by Monseigneur Depery, Bishop of Gap, the Séyères chapel is dedicated to Saint Guillaume. Near to Calme priory (under Mont Dauphin Fort), in the 12th century, little Guillaume was born without a right hand. While he was looking after the flocks belonging to the monastery, he received several visits from an angel announcing that the priory would be destroyed by a flood. With each alert, Guillaume, warned the monks but in vain. The angel gave him his missing hand in order that his message should be understood. If the convent was evacuated before the expected flood only a small chapel attached to the Western slope of the Mont Dauphin rock remains.

Flora
Rhododendron ferrugineux

Also called the Rose of the Alps, this medium sized shrub likes the rocks, the grassland and light woodland. Its hairless smooth edged leaves are dark green and shiny underneath. A bright pink colour its fragrant flowers are grouped by 6 to 10 at the end of the branch. Be careful not to ingest its fruits, oblong 4 to 7 mm long capsules: they provoke vomiting, diverse digestive, nervous, respiratory and cardiovascular problems.

Fauna
Rock Partridge

Here is another gallinaceous bird, like the Rock Ptarmigan, most easily observable at mating time in Spring. Perched on the promontory to sing in its jerky fashion, the Rock Partridge is recognizable by its grey back, its striped sides, its white throat and its red beak. It lives in the mountains on slopes that are well exposed to the sun and prefers rocks and moors where the young can feed on insects which are necessary for their growth.

History
Mont Guillaume Fraternity of Priors

70 members strong, this fraternity of lay men « which undertakes the maintenance of the chapels, oratories and crosses, to carry out works of solidarity, and to continue to bring to life the priory and its traditions » has existed since the 13th century. Even if each Prior is a Prior for life, every year the fraternity receives the support of two new members, chosen three years before: one living on the sunny side of the mountain (which is on the side of the town here), the other on the shadier side (the slope towards the countryside). There is no social distinction at the heart of the Priors. Lawyer, carpenter, barman, it is the same for everybody and they all share the same values.
