There is no minimum age to start bouldering in Petite Ile. Children under 14 years of age must be accompanied and supervised at all times by an adult.

We ask the parents, especially of the youngest children, to make sure that their children do not run and scream in the gym. This way we can make sure that all our climbers can exercise in a concentrated way.


The lessons for children and adolescents (from 6 to 18 years old) take place on Wednesday afternoon and Saturday morning. The lessons are a combination of technical training, playing games and free climbing. For the very young we use special sport equipment to make fun circuits that pose all sorts of playfull challenges. The lessons for adolescents focus on technology, flexibility and strength development.
