“De serres en valats”, or from ridge to valley, such is the leitmotiv of this superb endurance circuit, which takes you from the summit of mont Aigoual to the floor of the vallée Borgne to discover the Cévennes! Please take into account the technicality and duration of this circuit.

History
The meteorological observatory
Inaugurated in 1824, the meteorological observatory was built on the initiative of Georges Fabre, one of the pioneers of the reforestation of Mont Aigoual. His work with the botanist Charles Flahault enabled the creation of the arboretum of L’Hort de Dieu. The first meteorological data were gathered by agents from the French National Water and Forestry Commission. Since 1943, the observatory has been managed by the National Meteorological Office. It is France’s last mountain weather station that is inhabited year-round.
Flora
Short-grass prairies and heath on the summit of Mont Aigoual
Here, only species with a short reproductive cycle can settle due to the frequently glacial climate. The heath has been invaded by heather and mountain pine. This zone is barely wooded due to the violent winds and is comparable to subalpine vegetation, consisting of short-grass prairies and heather and blueberry moor. It is sometimes called pseudo-alpine.
Flora
The evolution of plant life
At the pass stands a schist menhir (standing stone). To the north, in Trépaloup ravine, hewn flint implements bear witness to a human presence in the region since prehistoric times. Palynological analyses (studies of pollen fossilised in peatbogs) have allowed scientists to piece together the plant life on Mont Aigoual from 8,000 to 5,000 BC. Pine predominated, accompanied by birch and hazelnut. Then pine populations gradually diminished. The damp climate warmed up, favouring the spread of oak and hazelnut. Finally, the increased damp and cloud cover at altitude allowed fir and beech to develop. From the end of the first century BC, the substantial percentage of grasses shows that forest had receded in favour of pasture and prairies. This was the start of the great deforestation.
Flora
Reforestation
In 1875, the French State initiated a reforestation policy. It bought up existing beech forests and bare parcels. This was the case of Aire-de-Côte and the land belonging to it. To settle poor soils, foresters planted a pioneering species: the dwarf mountain or bog pine. On more fertile soils, nobler species were planted: fir, spruce and larch. Commercial exploitation began in 1938, when the local mines bought the first harvests to shore up mine tunnels. The original reforested areas were thinned out and firs planted beneath the pines. It is said that in a bedroom at Aire-de-Côte, there was a heap of coniferous tree seeds at least one metre high. They were sown onto the snow, which dragged them into the soil as it melted.
Water
Le Coulet
At Le Coulet (meaning little pass), views open up onto the Mediterranean side, towards Valleraugue. The viewpoint lies on the watershed. Up to this point, the route followed the valley of the Bédil, a brook with a gentle, non-torrential gradient, whose waters flow into the Atlantic. Here, you discover the valley of the Clarou (a tributary of the Hérault), with its typically Mediterranean, i.e. more abrupt, profile. To the south, schist outcrops break through the slopes; to the north, the slopes are entirely wooded.
History
A Resistance refuge
In early 1943, the first Resistance group of the Cévennes was formed. The refuge of the Aire-de-côte group was one of the wooden shacks used for forestry works, whose roof was camouflaged using branches. On 10 July 1943, a message warned the post office in Rousses that a German attack was imminent. The Resistance was informed – but a storm delayed the group’s departure. The Germans arrived… The forester was arrested as an accomplice, accused of being in radio contact with London. Indeed, the Aire-de-côte Resistance listened to a crystal radio set built by the two Jews who were hiding there.
History
Aire de Côte
Aire-de-Côte farm was purchased by the French State in 1862, during the period of reforestation. Before the farm became a stopover gîte, it was for a long time the residence of the local forester and his family. In the first half of the 20th century, Aire-de-Côte was very different. To the north, behind the house, was the draille (drovers’ road), lined by upright stones and 40 to 50 metres wide. Thousands of transhumant animals passed every year on their way to or from summer pastures. The transhumant animals stopped there at lunchtime, then continued on towards Mont Aigoual.
Architecture
The village of St André de Valborgne
As you stroll along the quay above the river, you can still see the handsome bourgeois houses dating from the silk boom. If you look around, former spinning mills and industrial buildings dedicated to silk farming can still be seen in the landscape. A little lower down, opposite the 16th century château, you can listen to
Bernadette Lafont on the Camisard saga in and after 1702. As you reach the square again, quench your thirst at the fountain and have a look inside the Romanesque church (12th century).

Description

Signposts will guide you all along this route. In the description below, the signposted place names and/or directions are given in bold italics between quotation marks:

From the observatory, head due east, then towards “Combe de Lambert” (1) follow “Col de l’Estrade”, “Côte 1100” and “Coulet”. Continue on level ground to “Aire de Côte”. Take the left just before the gîte (2) towards “Sestrière”, then follow the ridge to “Col Salidès” (3). Descend immediately on the right on a wide track which becomes a stony path. At “La Fare”, technical descent (4) on the left before you cross the stream, then a technical climb to the other side. Further on along the track, do not miss the fork to the left (5) through the woods to join up with the road and then continue on the right to “St-André de Valborgne”.

This circuit is taken from the guidebook Massif de l’Aigoual, published by the communauté de communes Causses Aigoual Cévennes as part of the collection Espaces naturels gardois and the label Gard Pleine Nature.
