At ICP Boulder Hall, we use climbing holds to create climbs at various difficulty levels, which are organised into colour-coded circuits, known as “problems”. This allows you to determine your level and instantly identify climbs that you may enjoy trying out. Each coloured problem is marked with start tags to place your hands, our grading system is shown on these tags to help you find the right level for you. We also use large grey wooden boxes known as “Volumes” which are used to change the shape of the wall and can be used in any coloured climb, adding an additional layer of challenge and excitement to your bouldering experience.
