The McDowell Sonoran Conservancy is a non-profit conservation organization that relies on more than 400 volunteers to help protect and promote the McDowell Sonoran Preserve.  We do this in so many ways- from trail building to patrolling the trails, guiding hikes, education, and research.

We need your help!  The Preserve is growing by 10 square miles in the next year and we need volunteers to help keep the Preserve protected. Sign up today at

Dogs are welcome in the Preserve but only service dogs are permitted on guided hikes.

I started the group because there wasn't any other type of group like this. I've met some great folks in the group who have become close friends and have also met some amazing business owners.
