Massacre Forest trail

The Maison du Parc, which serves as head office for the High-Jura Regional Natural Park, has remarkable architecture and shingled facades. It offers visitors a chance to discover the region through exhibits, projections and a tour of a “Grenier-fort” (a strong attic). The exhibit takes visitors through each of the aspects of the High-Jura, in a colourful, modern and interactive setting: landscapes, nature, craftsmanship and industries, tourism, agriculture and forestry. An acoustic stroll offers an unexpected, poetic and vivid opportunity to submerge oneself into nature in the High-Jura through its exceptional sounds. Finally, two remarkable and recent films on landscapes complete and illustrate the visit: one on the geology of the Jura massif and the other on peat bogs.

Typical of these environments, the great yellow gentian will be by your side every step of this hike. A fun fact: if you squash the gentian’s fruit between your fingers, do you recognise the smell? It smells of peas.

The road you are on is called “Route Royale” (Royal Road) or “Route du Sel” (Salt Road), which once linked Saint-Claude to Geneva via Mijoux and Gex. At the time, the Jura would sell salt from Lons-le-Saunier to Switzerland. The road was built in 1742 by “corvées”: taxes paid in days of work.

How beautiful and natural are the High-Jura forests? Did we say natural? Well not entirely: they bear the mark of Man, who has exploited these lands for centuries. Here, forests are “managed”: mature trees are harvested first, a diverse range of species and ages are preserved and the forest regenerates by itself. Local knowledge is used to serve a diverse range of wood activities (carpentry, construction, cheese boxes, shingles, toys, firewood, etc.).

There’s no approaching a forest on a spring morning without hearing the song thrush. Its loud chant is essentially based on short musical patterns that it repeats two or three times. It builds its nests in forked branches.

Here, you are at an altitude of 1200 metres. Altitude decides which trees are found in the forest, based on each species’ preference. The two main coniferous trees in this forest are the spruce and the pine tree. A few small details set these trees apart. Can you tell which is which? The spruce has brown bark and round needles, whilst the pine tree has a greyer trunk with flat and vivid green needles.

Low dry-stone walls have outlined Jura landscapes for centuries. They set out the limits for plots of land, mark the frontier between France and Switzerland, border hay fields or vegetable plots and flank the “vies” (lanes). Built without any binding agent, these dry-stone walls are constructed according to ancestral building practices. Now typical features of these landscapes, they are also home to a remarkably diverse fauna and flora.

Further north, the Forêt du Massacre (Massacre forest) is home to one of the High-Jura’s most iconic birds: the western capercaillie. A sign of the diversity of high forests, this bird - also known as the wood grouse - is omnipresent here. The male favours old forests, while the female, who moves around more, prefers to spend her winters in bushy areas and raise her young in clearings. This bird is particularly sensitive to disturbances in the winter. There isn’t much chance of seeing one, but if you do, be sure to stay quiet and make the most of this extraordinary moment.

During the 19th century, pastures held more value than woods. Dividing land at each change in generation would have led to these lands being progressively split up until they lost all value. For this reason, families in the High-Jura found an original legal arrangement to share inheritance without dividing plots of land: “what is grown must grow”. With what is grown being the trees, and what must grow being the grass that is harvested as hay or that is grazed on every year.

When the forests started being cleared during the 12th century, driven by the monks of the Saint-Claude abbey, residents of the High-Jura opened-up the High Combes. They created vast areas for grazing, in which they built cabins useful for milking in the summer. The cabin to your right, at the bottom of the combe below the road, is called the “Cannonière”. Its architecture is typical of cabins in this region. It is one of the rare examples that is still used for agricultural purposes. Here, pastures are used by Montbeliarde cows, who produce milk for cheese.

You are now between a pasture and a forest, which is typically known here as a wooded meadow. Typical of the High-Jura landscape, the preservation of these environments is closely tied to grazing habits and they tend to close up as soon as grazing decreases.

To the left of your path, you will see a “grenier fort”, or a strong attic, set back from the main house. What is in there today, no one knows. But do feel free to visit the strong attic of the Maison du Parc in Lajoux. The keys alone are worth the detour!

The Haute-Joux conquest started here in the 5th century. During the 15th century, a type of serfdom imposed by the very powerful Saint-Claude abbey forced families to stay under the same roof: this was called mortmain.

The prairies stretching out before you are one of the High-Jura’s treasures. Here, hayfields contain a wide range of plants. Never laboured or sown, most prairies in the region are natural.
