Warning: This trail is nót wheelchair accessible! A beautiful beautiful trail going through the rocky and hilly forest of Fontainebleau. I loved it!! Very doable if you're in decent shape. Great daytrip. Stunning views, great variety of landscapes, a lot of climbing/jumping. (You can almost always go around if you don't like too much rockclimbing.) Note: I did the trail exactly as it was depicted on the board there. (Following the red markings.) My Garmin says the trail was ca. 20km and height gain ca. 700m! Keep that in mind. Also the markings can be somewhat hard to find sometimes. GPS recommended. And like all the others say: bring a lot of water (min 3L pp) and enough lunch/ snacks

Un parcours randonnee tres sympa qui demande un minimum de condition physique en marchant compter 4 a 5 heures sans les pauses. Prevoir boisson (minimum 2 a 3 litres) et le casse croute sans rien laisser au sol svp. Un parcours sportif difficile pour qui a envie d’aller au bout de soi. Record perso en 1h50, a vous de jouer ! Penser a avoir de bonnes chaussures et une tite trousse a bobologie avec une bande elasto, ca peut servir... De beaux points de vue, du sable, du rocher et de la grimpe ! Allez, courage fuyez !! ;)

Nous sommes partis à 4 dont 3 en très bonne condition physique chargé de 10 kilos sur le dos. Ne sous estimez pas la difficulté de ce parcours, il mériterait pour moi d'être classé en "Difficile" plutôt que "Modéré". Si vous êtes comme nous, un peu casse cou et à la recherche d'un défi physique n'hésitez pas. Il y'a de bon endroits à escalader ou pour tenter des sauts risqués. Rando très sympa, nous y retournerons sûrement, donc si vous aimez la difficulté et les chevilles tordues n'hésitez pas mais prévoyez assez d'eau. Nos 3L ont été suffisant mais ont dû être rationés sur la fin du parcours, ne faites pas la même erreur !

Je suis en bonne condition physique (env 1h de sport /j) et ce parcours m’a paru difficile plutôt que « modéré ». Fait en 5h sans compter les pauses, prenez de l’eau au minimum 2L/personne idéal 3L. Il faut impérativement de bonnes chaussures. Superbe parcours.

Attention ! Ne vous fiez pas aux kms !!! Prévoir pique-nique et beaucoup d’eau car il vous faudra entre 4h et 5h pour réaliser ce parcours en marchant, enfin devrais dire grimpant ! Comme son nom l’indique 25 bosses ça monte et ça descend presque en permanence, la souplesse, les articulations sont mises à rude épreuve. Très beau parcours, ça vaut vraiment le coup. Mais oui vraiment n’oubliez pas 2litres minimum 3litres est l’idéal, surtout s’il il fait chaud, car vous n’en trouverez pas sur le parcours Enjoy
