You can book in advance or at the last minute. We ask you to book in advance a maximum of 2 times per week to give everyone the opportunity to climb. 

If there are still time slots available 24 hours before the timeslot begins, you will be able to book again.

A separate reservation is no longer needed for Allez Up and Allez Out. As of August 3rd, climbers can access the indoor centre and the oudoor bouldering walls at all times when they reserve.
