Cliff development, rope access work & geotechnical engineering
Une Histoire de passion pour la montagne avant d’être une entreprise familiale
30 ans d’expertise alpine au service des environnements complexes
Avant d’être Roc Aventure, il y a une trajectoire forgée dans la montagne.
L’entreprise est fondée par Christian Ferrera, grimpeur passionné issu d’une lignée profondément liée au rocher.
Dès les années 1980, il équipe de nombreuses voies d’escalade à une époque où l’engagement est total : ouverture par le bas, matériel limité, lecture du terrain essentielle. Son expérience, lui a permis de développer, une capacité rare de lecture du terrain, choix d’itinéraire et gestion du risque.
Ce savoir-faire est aujourd’hui transmis et prolongé par son fils, David Ferrera, garant de cette continuité technique et humaine.

June 2026 – Rehabilitation of the climbing area of Loup Hurlant – Puy-Saint-Vincent (Hautes-Alpes)
Complete rehabilitation of the main climbing area at Puy-Saint-Vincent, located on the Tournoux cliff.
The work involved the complete replacement of aging equipment, the thorough cleaning and removal of loose rock from the cliff face, and the restoration of approximately twenty high-level climbing routes.
This iconic area, renowned for the quality of its rock and its highly technical nature, is one of the most remarkable climbing sites in the region.
May 2026 – Reconstruction of the footpath of the Via Ferrata of Saint-Christophe-en-Oisans (Isère)
Following a rockfall that damaged the existing structure, ROC Aventure completely dismantled the old bridge and then designed and installed a new one.
This work has permanently restored the continuity of the trail while improving its strength and safety.
End of May 2026 – Replacement of a footbridge on the Via Ferrata of the Torrent de la Combe – Puy-Saint-Vincent (Hautes-Alpes)
Due to the progressive instability of a rock face supporting the existing structures, the route has been modified.
The old footbridges have been removed and replaced with a new structure providing direct access to a stable rocky area.
This intervention ensures the long-term viability of the route while improving user safety.
Maintenance and upkeep of sports facilities
Throughout the year, ROC Aventure provides upkeep, inspection, and maintenance for a large network of mountain sports sites: via ferratas, climbing cliffs, treetop adventure courses, and obstacle structures.
Our services include:
Inspection and monitoring of equipment;
Removal of unstable boulders;
Clearing and maintenance of access routes;
Replacement of worn components;
Repair of footbridges and metal structures;
Technical expertise and support for local authorities.

A methodology
Our approach is based on a fundamental principle:
Intelligent route selection before any technical intervention
Thanks to our expertise in reading rock formations and identifying natural weaknesses, we optimize routes to:
Reduce risks (particularly rockfalls)
Limit environmental impact
Decrease the need for heavy equipment
Ensure the durability of the installations
