Located inside the Avatar fitness centre (Avatar Centrala Ruchu) just northeast of the centre, this wacky, wonky, technicolour climbing centre for kids (and adults!) of all ages takes the intimidation out of rock climbing and makes it a fun adventure. Featuring 12 unique climbing walls with crazy grips shaped like everything from Tetris blocks to stars and planets, defeat them all, race your friends to the top, and leap like Tarzan onto a giant swinging banana (no, really). Thanks to their auto-securing system everyone can climb independently. In terms of climbing centres, this one is the most fun we've seen, and a perfect place for birthday parties, integration events and simple family time. Each session is 1hr (40/50zł) and the number of climbers admitted at once is regulated; groups are also common, so it's best to reserve online or call in advance. To get there, hop onto buses 103, 113 or 413, getting off at the 'Sikorki' stop.
