Cedar Ridge Preserve
The only equipment allowed at Cedar Ridge Preserve are your own two legs. But that's okay. With 600 acres, 10 miles of trails, butterfly gardens and picnic areas, there is plenty to keep you entertained. Run by Audubon Dallas since 2003, Cedar Ridge Preserve is about 20 miles outside of Dallas and offers an elevation of 755 feet. The preserve is not meant for large groups, but its picnic areas are family-friendly and clean.
Although not the longest, Fossil Valley Trail is the most difficult. There are no water fountains in Cedar Ridge Preserve, so BYO.
