Are you keen to try out some bouldering? Than submit to an introduction lesson. An enthusiastic instructor will tell you all about the do’s and don’ts and teach you some basic skills.
If the times of the introduction lessons don't fit you well, you can still come over. An introduction lesson is not obliged, so you can start bouldering on your own as well.
What do you need? Actually not much. Just wear some comfortable clothes and clean sportshoes and you are all set. It is also possible to rent a pair of climbing shoes for €3,50, which makes climbing much easier
