"Walkers and mountain bikers use the same paths without restrictions. This is made possible by a tolerant and considerate attitude on all sides. Mountain bikers slow down to walking pace when overtaking and stop when encountering walkers on narrow paths to make way for them. Mountain bikers brake carefully to avoid blocking the wheels and damaging the trails; they also do not leave the trails. Walkers accept mountain bikers as equal users of the path and give way wherever possible and reasonable."
