Welcome to the 50 Things Every Child Should do before age 12. We can't really take credit for this list, as it was heavily inspired by a list put out by a wonderful U.K. organization called The National Trust. They update their every year. We took one version of it a few years back, removed things that didn't resonate with us, and added our own "musts." We hope this provides you with some outdoor inspiration!
