If you’re 8 years old or over, you can come bouldering! For kids aged 8 – 11 years old you need an adult (18+) supervisor and maximum 3 kids in any group. From 12 years old you can come boulder independently. You don’t need a course or introduction class; just come over and we will explain the rules of bouldering and the safety regulations.
Bouldering can be done on clean indoor sports shoes, but a better experience can be had on real climbing shoes. These can be rented in our gym and are compulsory if no suitable shoes have been brought along. Caught the bouldering bug? Join our youth training: the Radium Radicals!
Wanting to come with more than 3 kids? Bouldering is only allowed under the supervision of a Radium Boulders instructor. Please make your reservation here.
