About

Isatis

Isatis opened in 2025 as Liège's second bouldering hall, 100 metres along the Avenue Albert Ier from L'Éléphant, in Grivegnée. It has about 800 m² of climbing on clean, modern walls fitted with the latest holds, with problems for every level from beginner to expert, and a new sector is set every week. For training there's the largest model of Kilter Board and a training rack.

The bar doubles as a cultural space that hosts exhibitions, concerts and DJ sets. Multi Pitch, a climbing shop, is on the mezzanine above the bar and opens from Wednesday to Saturday, 14:00 to 18:00.

Isatis belongs to the same group as L'Éléphant and Top Rock, the group's rope-climbing hall. A single entry or a 10-entry card can be used at whichever of the three you choose, and memberships cover all three.

Courses and competitions

Isatis focuses its courses on adults: four-session beginners' courses run on Wednesday evenings, four times a year, and end with a free month's membership. The hall also hosts competitions, including the Belgian youth bouldering championship in February 2026 and an open bouldering contest with a DJ in October 2026.
