A small climb above a picturesque village... From one bend to another the panorama is more and more stunning until you arrive unexpectedly on a plateau.

Arriving at the Fort, what a pleasure it is to come out on to a vast plateau of meadows. The panorama, from Barle summit along to Serre Ponçon lake, is magnificent. The North is dominated by a, summit with steep dry slopes: this is the Roche Méane which reaches an altitude of 2650 m !

From the carpark, start by following the Pisse torrent, channeled at the bottom by a dam which protects Réallon village. On the left, look out for the remains of the low dry stones walls which bear witness to ancient agricultural terraces. Then follow to the left taking a bending path that crosses a small forest of oaks and pines.

Fauna
Black Redstart

Mr. Black Redstart sports a grey skullcap and white marking on his wings, a black tail and rump. Originally a mountain bird, it has adapted to other environments, as long as there is a rocky atmosphere. Which is the case here, on the slope of the Roche Méanne. The Black Redstart is a common bird, bright and very lively: it constantly hunts insects in flight and on the ground. Often perched up high on a wall or a rock, it makes brief cries of alarm while bending its legs. Its chatty song, punctuated with sounds of « paper rustling » is characteristic. Partially migratory, it spends winter in the bottom of the valleys.

Common Rock Thrush

The Common Rock Thrush likes sunny rocks. It only visits us in April until the end of August to nest either on the ground, or in a rock cavity. Orange breast, blue head, white rump, its song consists of sweet, clear melodious stanzas.

Rock Partridge

The Rock Partridge lives in the mountains on well exposed slopes, like those here at Roche Méanne. Every two years, the Ecrins National Park rangers count how many there are on this slope. Before sunrise, they take position in their different « sections » with small tape recorders to imitate the song of these birds. « We listen attentively in case there is an answer ». The song indicates the presence of a « singing male ». « Sometimes we only hear their song, but other times, suddenly, the silence in the mountains is interrupted by the crashing of beating wings which makes us jump. We just have the time to count them and then we see them diving off at top speed ».

Flora
Oaks and Pines

Oaks and pines live here together. They replace the ancient hay meadows once maintained by the inhabitants of Réallon. The pine forest consists of Black Pines and some Scots Pines. The Austrian Black Pine has long, rigid, prickly dark green needles; those of the Scots Pine are short, twisted and bluish green. Due to its hardiness, The Austrian Black Pine was introduced in the 19th century and was often used to restore the eroded soil of the Southern mountains. This was the case on the « sunny » (Southern slope) at Réallon where it was planted by the Mountain Restoration Service at the beginning of the 20th century to stabilize the slopes and to protect the village and the road.

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. Its little round black droppings in piles called « moquettes » in French! Sometimes it is a deep sonorous and guttural bark that resonates in the woods. Have a listen!

Squirrel

Did you know that the squirrel uses a very elaborate language? It is a sign language, with mimics and expressions, without forgetting the movements of its tail.  It also possesses quite an extensive range of sounds. It cackles, yelps, growls or groans, it also chatters. So if you don’t see it come out of the woods, don’t make a sound, maybe you will be lucky enough to hear this animal secretly expressing itself.

Short toed Snake Eagle

This dry thermophilic slope shelters several reptiles like the Wall Lizard, the Green Lizard, the Aspic Viper or the Grass Snake.  The Short toed Snake Eagle essentially eats just reptiles!  From the month of March, you will be able to see these large birds flying together in the sky, alternatively swooping and hovering like two silver coloured kites playing in the wind.. Their light coloured stocky silhouettes, their darker coloured heads leave not a shadow of a doubt! The eagles are back.

Water Pipit

This little bird in the Passeriforme family can make itself invisible by flying about against the blue of the sky. It is very discreet. Although, it does know how to make itself heard by calling its name : « pi-pit-pipit-pipit-pipit » and all of a sudden, from its highest point of flight, it lets itself glide to the ground, with its wings out like a parachute it makes a jubilatory « piiiiii » sound ! Once it has landed in the meadow grass, it is difficult to see it among the tufts of Festuca.

Archaeologie
The « Clot du Fort » and its canal

With a surface area of approximately 30 ha, the plateau, popularly called the « Clot du Fort », has been used for the cultivation of cereals since Antiquity. At the beginning of the 20th century, a canal measuring around 2,5 km was built from the Pisse torrent to irrigate, via a multitude of secondary canals, 90 privately owned plots. Since these plots having been progressively given over to sheep grazing the canal has fallen in to disuse. It is now reduced to remnants; the path enables you to follow part of the belvedere.

History
Réallon Castle

Réallon Castle was no doubt built during the middle of the Hundred Years’ War. Its location enabled it to control different means of access in to the valley thanks to the Champas ravine at the East of the enclosure and to it being partially constructed on a sloped terrain. The castle consisted of a dungeon and a vast enclosure which was used as a refuge to shelter the populations around Réallon in the case of a military attack. This enclosure was confined by a semi-circular tower opened towards the inside. Following the initiative of the community of Réallon, this place known as the « Tour à la Gorge », was completely restored in 2013 with the help of the Ecrins National Park. .

Fauna
Marmot

Some of them live on the plateau. This is the hikers’ favourite animal. Maybe you will be lucky enough to see it or to hear it whistle. This big rodent is only visible between April and October it takes refuge during the coldest season in its burrow where it hibernates. It lives in a family, respecting a strict hierarchy. Games, grooming, fighting and bighting create the dominance of the couple and the cohesion of the group. Each one participates in installing the boundaries by rubbing their cheeks on rocks and by depositing droppings and urine. When there is danger, the marmot makes a strong shrill whistle in order to warn the others.
