Welcome to City Bloc the home of Leeds's first dedicated indoor bouldering centre Passionate about bouldering and through years of training and competitions home and abroad we hope to bring you the best ideas from climbing walls around the world. With 475 square meters of climbing we have 150 boulder problems ranging from very easy to very hard and a section gets reset every week so there's always new climbs to have a go at. Every year we have a series of competitions running through the winter and the summer months which have a range of climbs from very easy to very hard and are aimed at everyone.
