The 25 bumps course ("circuit des 25 bosses" en France), located in the Fontainebleau forest in France, is a very popular hiking route that offers a unique experience for lovers of nature and physical exercise. Known for its varied landscapes and physical challenges, this circuit is often compared to a real terrain of adventure, setting itself apart from other trails in the region. It is the ideal place to prepare a mountain trek because it offers a positive difference in altitude that is rare to find in Ile-de-France.

Itinerary description: The route (or circuit) of the 25 bumps covers approximately 16 kilometers and, as its name suggests, involves the ascent of 25 rocky hills, accumulating a positive altitude difference of about 800 m. Although the distance may seem modest, the rugged nature of the terrain with its constant ascents and descents requires good physical condition and can take between 5 to 7 hours to complete. This route forms a loop that starts and ends at the La Troche car park, making it easily accessible to hikers with a vehicle. However, it is difficult to access by public transport.

Interesting passages: Among the most remarkable elements of the course are the spectacular views offered by the various bumps. Hikers can enjoy exceptional panoramas of the Fontainebleau forest and its surroundings. In addition, the rock formations, typical of the region, add an aspect of light climbing that makes the walk all the more exciting and varied.

Value of the course: Compared to other trails in Fontainebleau, which may be gentler and focus on family walks or leisurely nature observations, the 25 humps course attracts those looking for a more challenging activity. It is the ideal choice for hikers looking to test their stamina and agility. In addition, the wild and preserved nature of this course makes it a privileged place for those who want to get away from the beaten track and experience a more authentic adventure.

The 25 bumps course is therefore a must for hikers looking for challenges and natural beauty. It combines physical effort, the pleasure of discovery and the satisfaction of completing one of the most demanding circuits in the Fontainebleau forest. Whether for training or simply for the pleasure of adventure, this course offers a rewarding experience in nature.
