La traversé de la dent de Crolles est géniale mais demande un bonne condition physique. Cyrille (le guide) connaît très bien son sujet, sait mettre tout le monde en confiance et gérer les situations délicates avec calme. Vous pouvez-y aller les yeux fermés (de toute façon il fait noir sous terre).

Si tu recherches une belle aventure, en déconnexion totale avec le monde qui est le tien, des sensations avec une pincée d'efforts, de l'entraide, alors n'hésite pas, fonce, tu auras quelque chose à te mettre sous la dent (de Crolles) et Cyrille sera le meilleur des guides.
