If you love hiking the trails in the McDowell Mountains as we do, you’ll be interested to know that they and all of the Preserve are monitored and cared for by the McDowell Sonoran Conservancy. When all the Preserve is purchased, one third of Scottsdale’s land will be preserved. It will be the largest preserve in any major metropolitan area of the United States. Hundreds of people volunteer to help the McDowell Sonoran Conservancy accomplish it’s goals of caring for the Preserve. They are always looking for more volunteers. Help take care of one of the gems of Scottsdale by volunteering!
