Who are we?

Boulderfest one of the only outdoor bouldering events in the Western US. We began in 2011 to provide a space for climbers to gather, have a little fun, and network. Over the years we have become an iconic Idaho event. A space to meet up with friends new and old, as well as a chance to give back by participating in the annual Adopt-a-Crag clean up.
