The fact that this preserve is hiding right in Charlotte boggles my mind. If you need a nature fix and don't feel like driving out of the city, this is probably your best bet. My wife and I wandered around and explored most of the trails. As other reviewers have said, you can expect to be one of the only people here. We saw two other people on the trails and a family at the picnic area at around 10 on a Saturday morning. I think RibbonWalk was undergoing some maintenance when I visited, because some of the trails were inaccessible and others were poorly marked.
Overall, it's definitely nice enough for a return visit. My dog would love it, so he'll be tagging along next time.
