A meeting where the participants try the boulders together with the best specialists in the world, sharing a healthy, vital passion in the open air. Melloblocco does not use structures of any kind and simply enhances what nature has made available. Melloblocco is also attention to how we move in natural environments because we all have an impact, because even the spaces for adventure and climbing are not infinite and must be preserved. For this reason, it was decided not to add any new area to the immense existing bouldering park, to favour the recovery of a part of the thousands of boulders of all difficulties that dot the valley.
