The cave of the oath is quite surprising, especially because the vault is made of a single rock. The letters D.F.D were engraved on the cave by Denecourt himself and mean "Last Madness Denecourt".

It's a great passage on the sidelines of the Denecourt-Colinet trail n ° 8, where we slalom between the rocks! It is as beautiful as it is fun.

The 'canyons' in Fontainebleau are not traditional river-carved canyons but rather unique sandstone rock formations. These create a labyrinthine landscape of gorges, narrow passages, and rocky outcrops, making the area globally renowned for bouldering and hiking. They offer diverse challenges and scenic beauty within the distinctive Fontainebleau forest.
The gorges around Fontainebleau are primarily popular for bouldering and hiking. Areas like Apremont gorge and Gorges de Franchard offer extensive bouldering circuits for all skill levels. Hikers can explore scenic trails that wind through these rocky landscapes, such as the Denecourt-Colinet trails passing through Grotte du Serment and Gorges du Houx.
Yes, many areas within the Fontainebleau forest are suitable for families. The Trois Pignons area, for instance, offers numerous boulders that are lower in height with soft sandy landings, making it ideal for beginners and families. The varied circuits and unique rock formations provide an engaging environment for children to explore. Always check specific trail difficulties before heading out.
Beyond the well-known Grotte du Serment with its single-rock vault, you can explore the vast and rugged terrain of Gorges d'Apremont, known for its extensive bouldering and the 'Caverne des Brigands'. The Gorges de Franchard are famous for their sharp rock and a 6km 'mountain circuit'. For a unique narrow passage, Rocher des Étroitures offers an almost canyon-like geological feature.
The Fontainebleau gorges are enjoyable year-round, but spring and autumn offer the most pleasant conditions for hiking and bouldering, with milder temperatures and beautiful foliage. Summer can be warm, but the forest provides ample shade. Winter visits are also possible, offering a different, often quieter, experience, though some paths might be slippery.
You can expect breathtaking panoramic views of the dense forest and unique rock formations. Highlights like Apremont Gorges Panorama and View of the Gorges de Franchard offer expansive vistas. The landscape is characterized by extensive woodlands interspersed with dramatic sandstone outcrops, creating a picturesque and rugged scenery.
Yes, the area holds historical significance, particularly related to Claude-François Denecourt, who pioneered many of the marked trails. For example, the Grotte du Serment (Oath Cave) features engravings by Denecourt himself, reading 'D.F.D' (Last Folie Denecourt). Many trails, like those passing through Apremont gorge and Gorges du Houx, are part of the historic Denecourt-Colinet network.
Hiking difficulties vary from easy strolls to more challenging, technical routes. Many trails involve walking on huge rocks and navigating narrow passages, such as those found in the Rocher des Étroitures. The 'mountain circuit' in Gorges de Franchard is a 6km route offering a physically demanding experience. Always check trail descriptions for specific difficulty ratings.
Absolutely. The Fontainebleau region is a hub for various outdoor sports. You can find numerous options for hiking, including moderate trails like the 'Walk of the Viewpoints'. For cyclists, there are road cycling routes and gravel biking opportunities, with routes like the 'Coquibus Pond – Route de Sully loop' available.
While many areas are popular, exploring beyond the main circuits can reveal quieter spots. The Gorge aux Néfliers – Route du Milan offers a beautiful trail through forest and rock formations that might be less frequented than the more famous bouldering sectors. The vastness of the forest means there are always new corners to discover.
Given the varied terrain, it's advisable to wear sturdy hiking shoes or approach shoes with good grip, especially if you plan on bouldering or navigating rocky paths. Layered clothing is recommended to adapt to changing weather conditions. For bouldering, comfortable, flexible clothing is essential. Always check the weather forecast before your visit.
