Birmingham Boulders is a new project from First Avenue Rocks. Birmingham Boulders is big! With over 12,000 square feet of climbing in a facility that is more than twice the size of our First Avenue Rocks facility, this means Birmingham Boulders will be the largest bouldering gym east of Colorado. Our new space has allowed us to expand all of our programs: more bouldering terrain, an expanded kids and family area, and more training- a lot more training.
