Tree climbing is an itinerant and ephemeral outdoor activity accessible to all, practiced with the greatest respect for trees and their environment. It resembles the instinctive climbing of childhood, with the added certainty of climbing in complete safety thanks to the supervision of qualified instructors and the use of standard equipment. In addition to the immediate pleasure it provides, it also raises awareness of the tree and its environment, which is all the more essential in these times when there is still undeniably a natural affinity between Man and the Tree in each of us.
