J’ai passé une excellente journée sous terre avec Cyrille où j’ai enfin pu réalliser un rêve de 20 ans. Donc un grand merci à Cyrille de nous avoir guidé dans cette aventure à travers tous ces boyaux et ces puits. Les vues sont incroyables et le parcours ne manque pas de piquant.

Nous avons effectué la traversée de la dent de Crolles : Une expérience magique et unique! Je recommande vivement cet “ballade” si vous êtes un peu sportif. Notre guide a été super sympa et parfait pour nous accompagner et nous mettre en confiance.

Une sortie de spéléologie mémorable avec Cyrille, un guide qui sait vous mettre en confiance tout en vous responsabilisant. Il vous racontera l’histoire de la découverte du réseau de la Dent De Crolles, la géologie et plein d’anecdotes. C’était notre deuxième traversée souterraine. On a adoré. N’hésitez pas à contacter Cyrille, il pourra vous proposer une sortie adapté à votre niveau et à vos attentes.

Une journée exceptionnelle…. Cyrille a été un excellent accompagnateur… passionné par ce qu’il fait et qui en plus de nous guider et nous conseiller sur le parcours nous a raconté plein de chouettes histoires sur la spéléo et le parcours que nous avons fait ! Première expérience de spéléo pour moi et j’ai adoré…. le parcours est vraiment riche en découvertes… on en prend plein la vue .. de superbes paysages souterrains 🙂. Bref vraiment inoubliable comme journée!

Zeer leuke eerste ervaring in de grotten met Cyrille! Op voorhand een uitgebreide mail ontvangen zodat we de dag konden voorbereiden. Welke kleren, schoenen handschoenen voorzien. Wat en hoeveel drank meenemen enzovoort… De tocht door de grotten (ontdekking) was heel mooi, gevarieerd en met voldoende uitdaging. Cyrille past zich volledig aan de groep aan en helpt waar nodig. Zeer toffe dag en een aanrader voor jong en oud.

Cyrille nous a amené faire « le trou du glaz » avec notre fils de 17 ans, superbe expérience ! Cyrille est patient et pédagogue, on a fait de la géologie, de l’histoire locale, et on a rampé, fait des descentes, appris le maniement du matériel pour les remontées. !!! Aventure à tenter sans aucune appréhension puisqu’on est bien accompagné. Merci Cyrille !

Traversée Glaz-Annette avec Cyrille. Encadrement au top. Conseils et préparation en amont. Le jour J la journée s’est très bien déroulée. Cyrille prend le temps qu’il faut en fonction de notre niveau, répond à nos questions et tout ça dans la bonne humeur! La traversée prend plus ou moins de temps selon notre niveau. Merci Cyrille pour cette journée et ton encadrement !

Superbe première expérience de spéléo ! On a fait la sortie technique et j’ai beaucoup aimé les rappels et remontées sur corde ! Les volumes sous terre sont impressionnants. L’accompagnement de Cyrille est top. Professionnel, pédagogue, rassurant et décontracté, c’était vraiment appréciable !
