Wenonah Woods is open dawn to dusk, 365 days a year. Please respect the hours on these trails, especially as they often times pass right along the edges of people's property. Also, please use official trailheads and do not cut through people's property. These trails have some ups and downs, as well as some wet spots, although the town does an amazing job of maintaining them.
Thanks to SuperC00lGuy for the help with these caches!
