Help Us Bridge the Gap!


For over 40 summers we’ve welcomed hundreds of children to our summer camp program and watched them thrive as they deepened their relationship with nature and gained essential skills. As a result of the COVID-19 Pandemic, we had to cancel our summer camps this year.

We need your help! Our goal is to raise $25,000 by Labor Day – just half of what our summer camps would have generated.
