Jelenia Góra (Dolnośląskie Voivodeship) has 1 climbing gym in our database. We confirm data at the source; still, check hours and climbing type with the gym before you go.
Our database lists one gym in Jelenia Góra: Projekt Boulder on Jana Sobieskiego 47e. It is bouldering only — you climb low above mats, with no rope, harness or belay partner, so you can turn up alone. Open Tuesday to Friday 15:00–22:00 and 14:00–22:00 at weekends; closed on Mondays.
For anyone heading into the Karkonosze mountains this is the nearest indoor training spot. The other gym in the area, Pochylnia, sits in Jeżów Sudecki just outside town and has both bouldering and roped routes — that is where to go if you want to climb on a rope.
