Bytom (Śląskie Voivodeship) has 1 climbing gym in our database. We confirm data at the source; still, check hours and climbing type with the climbing gym before you go.
Skarpa Bytom operates in the Rozbark district on Kilara and is one of the few venues in the region open from 07:00 all the way to 23:00. It has both bouldering and rope walls, and the latter come with 22 auto-belays — the largest such zone in southern Poland. So you need no partner for either.
Bytom sits in the middle of the conurbation, so Katowice, Chorzów, Zabrze, Gliwice and Sosnowiec are all within a short drive. With climbing gyms this dense, it is worth looking at the whole region rather than a single city.
