The sandstones of Fontainebleau

Highlight • Natural Monument

The Fontainebleau sandstones are sedimentary rock formations. These sandstones are very popular with climbers for their unique texture which provides excellent grip. They are also popular with artists for their use in sculpture and construction. Here, runners and runners will find landscape interest because these rocks are not particularly high, unlike others.

Faisanderie bivouac area

Highlight • Rest Area

The bivouac zone of La Faisanderie is one of the authorized sites of the forest of Fontainebleau. The advantage of this one is the proximity to the city, its shops, its restaurants and all the services. The opportunity for a slightly more urban stroll before spending a night in the heart of nature. Otherwise, you can take a walk in the middle of the forest.

Gros Fouteau Road

Highlight • Forest

The Gros Fouteau road, in the heart of the managed biological reserve of Mont Ussy and Butte aux Aires, offers an immersion in unspoiled nature. This forest path winds through wild and varied landscapes, where century-old trees, such as the majestic Gros Fouteau, stand proudly. Here, you can discover the richness of the local biodiversity, with green clearings and magnificent viewpoints of the surrounding hills.

Augas Cross

Highlight • Viewpoint

Croix d'Augas - Fontaines path The start of the trail descends into the "combe" via a small section cut into the hillside. After, he follows the single-track "roller coaster" and goes back on a PR.

Chemin des Fontaines - Denecourt Tower The start of the descent is "shapée" and twirl around the parcel separation path. Do not go straight into the steep, it has little interest. Then took place a creation ex-nihilo which leaves on a small "crest" on the left: a single player player and quite rolling. A wooden NFB layout was made on a descent that was too sandy, where erosion was at risk. After, there is a small piece of track. The path from the Denecourt tower junction was remarkably landscaped by the ONF with sandstone from Fontainebleau on the exit to the tower.

Tour Denecourt - D116 The descent being on a very sandy slope, the ONF has built the only "pin" of the course, with wood, sandstone, a gabion ... We take a small piece of GR (we are courteous with the marchers) good technique in the rocks. Short track and we start on a single player that becomes more and more player (it goes up, it goes down, it turns, it goes up on a rock, etc.): a total creation for mountain biking.

Rock Cassepot The climb is done on a single challenge challenge, then a small piece flat trail but very technical. After a little bit of the "Road of the Viewpoints of the Rock Cassepot" we take on the right the new path created from scratch in January 2018 and which follows a face of size, avoiding the wetlands of the flats (botanical reserves ): great happiness!
Route Tournante - Croix d'Augas We cross the Route Tournante to take a brand new trail created in February 2018 and which starts below it. The climb on the Route Tournante is a small challenge! Once on the track to Guay, a single track without level but player joins the Augas Cross.

Calvary Cross

Highlight • Monument

A first cross would have been erected here in the 17th century, then destroyed in 1793 during the French Revolution (like many symbols and religious buildings). It was rebuilt in 1805, briefly became a place of pilgrimage before being destroyed again in 1830. It was rebuilt in 1837. From here, there is a superb panorama over the forest of Fontainebleau.
