Bloco is by far the best bouldering gym in Warszawa. I go here 2 to 3 times a week and with how…read moreoften they change routes, I never get bored. The place has routes for all difficulty levels. The staff are very friendly (and all speak excellent English) and are always open with climbing tips and answer any questions you have. They have regular and even advanced classes for folks interested in picking up bouldering or to improve to the next level.
Besides bouldering routes the gym has a dedicated Crossfit dock with classes all through the week; areas for your to relax and read if you are not climbing; showers and changing rooms.
The gym has a decent selection of snacks and drinks and ready made meals if you are hungry post climbing.
