From May 6th to 9th, 2026, Val Masino in Valtellina will once again transform into a meeting place for thousands of boulderers from all over the world. Online registration is now open.
Melloblocco is one of the largest and most renowned bouldering festivals worldwide. Since its first edition in 2004, the event has brought thousands of climbers to Val Masino in the Italian Valtellina region every year. The focus is on shared experiences, working hard until your fingers bleed, and connecting with like-minded individuals in a unique setting.
