Kalisz (Wielkopolskie Voivodeship) has 2 climbing gyms in our database. We confirm data at the source; still, check hours and climbing type with the climbing gym before you go.
Kalisz has two venues, both combining bouldering with rope climbing. Ściana Wspinaczkowa Kalisz on Chopina, inside the former Runotex building, is open daily from 10:00 to 22:00. Skałka Kalisz on Skalmierzycka operates at a school and does not publish a full weekly schedule.
That is why we mark Skałka as “hours unknown” rather than entering uncertain data — individual days show up online, but never the whole week. For a first visit, the Chopina venue is the safer bet.
