Any group of 6 or more climbers must notify the gym by email at groups@petite-ile.be with at least 72 hours notice before your visit. Our management team will help make sure payment and all required paperwork (such as invoices and other formalities) are handled properly before you arrive.

Large groups of climbers or multi-family groups who show up without a prior booking may be refused entry, at our staff’s discretion, depending on how busy the gym is.
