The La Joux Rock

This trail, mostly through forest, starting in the village of Rogna is scattered with dry grasslands and marked by the viewpoint from the La Joux Rock.

Along this walk through the joux (forest in Jurassian), the dry grasslands are a real treasure. As early as spring, a symphony of colours explode on these arid grounds: yellow, blue, mauve, white and pink. A palette of shimmering nuances appear successively throughout the seasons and dress this seemingly unchanging landscape.

Dry grasslands

Thin and nutrient-poor soil, sun exposure, low water-retention capacities and the almost complete absence of soil additives: these are the main characteristics of dry grasslands, also called “orchid lawns”. Mountain germander, Breckland thyme and laserwort are just some of the flower species that live alongside the early-purple orchid and the military orchid in this environment that attracts many butterflies. They are of unique ecological interest as over a quarter of protected species in France live in dry grasslands.

The forest’s new energy resources

Much loved by city dwellers as a place to unwind, the High-Jura forest currently covers 65% of the Park’s land. It was traditionally used to extract timber for framework or heating wood in quarters. But over the last ten years, an economy has developed that makes use of forest by-products (such as bushes, copses, branches, sawdust, sawmill waste) for heating. Turned into chips or granules, these by-products are used as fuel for private and collective automatic stoves and boilers. Three tons of forest chips is the equivalent of roughly one ton of petrol.

Fauna

The Eurasian lynx

Although, originally, this species could be found in all European forests, both in lowlands and in mountains, during the mid-20th century, it was only present in Scandinavian countries and in Central Europe. The lynx was reintroduced during the early 1970s in Switzerland and later in the Vosges in 1983. It progressively recolonised the French parts of the Jura and is now also starting to appear in the Alps. However, due to a high mortality rate amongst young lynxes (50%), its progress is slow. In the French Jura Massif, it is estimated that there are between 100 and 140 lynxes, and that there is somewhere between 130 and 180 of them in the whole of France.

Fauna

The great spotted woodpecker

In the spring, strain your ears and you will easily be able to find the great spotted woodpecker by following the echo of its “drumming” against a tree trunk (a series of quick pecking sounds). It can peck up to 20 times a second, at an estimated speed of 25 km/h! This birds beak constantly grows to compensate from the wear and tear caused by its incessant drumming. The great spotted woodpecker hunts for insects that are inside the wood, using its “harpoon”-shaped tongue. Wrapped around its brain, it whips out and reaches alarming lengths.

Viewpoint

Viewpoint from La Roche de la Joux

To the north, the eye is drawn to the rocky cirque of the Côte de Plana, where the chapel of Saint-Romain-de-Roche is built, on the edge of one of the Bienne’s water gaps, overlooking Vaux-lès-Saint-Claude. In the same line of sight is the viaduct of Villards d’Héria just before the archaeological site.

Viewpoint from Rogna

From the western edge of Rogna, a village with plenty of sun exposure, this viewpoint opens out to the east over the cirque of Vulvoz and the highest ridges in the Jura: Colomby de Gex and the Crêt de la Neige massif.

History & Heritage

Dual farmhouse

The farm was once more than a place for mere production. “A world within a house” and both an instrument for collective memory and a geographical marker, it represented both the buildings, the family inside, and sometimes even the craft performed there (sawmill farm, wood turning farm, etc.). In villages, you will notice that buildings are often organised in “spans”, mainly due to constraints relating to adjoining houses. Thus, each span tied the building to a specific purpose: stables, barns or housing.

Description

Starting at the ROGNA town hall, the trail (yellow and red waymarking) follows the D 293 towards Viry. After around 300 m, the gravel path ascends to the right and cuts through an allotment. Continue your ascent on a white path, initially bordered by meadows to the east, and that later enters the forest.

Head past “Chemin du pré Veyron” and continue on the main slightly hilly path, before reaching “Chemin du Bujon”, and La Mélie immediately thereafter

Head right (yellow waymarking), in a northern direction, on another forest path, with a more distinctive landscape which is muddy in some areas. The trail, which mostly ascends during its first half, abruptly descends to reach the end of a forest path, Under the La Joux Rock.

> The BELVEDERE OF THE LA JOUX ROCK is accessible in 30 minutes there and back. Ascend to the left via a very steep path for around 250 m. In a small combe, turn right onto a trail that approaches the ridge line and follows it all the way up to the summit.

On returning, take the forest path back to the village, heading past Pré Veyron. After the first houses in the village, descend to the right via “rue des Réservoirs” and return to the parking lot on your left.

Recommandations

Be careful along the edge of the cliffs at the La Joux Rock.

This trail passes through private property pastures with livestock and forest paths. To respect the owners and farmers granting you passage, and for the security of livestock and wild fauna, we ask that you remain on the waymarked paths. Use the adapted passageways to get across fencing and be sure to close gateways behind you.

Please keep your dog on a lead if you have one.

Wild flowers are beautiful, they may be rare and protected and often wilt quickly. Do not pick them! They will delight the next hikers.

In case of forest works (felling, skidding, etc.), for your safety, know when to stop and turn around.
