The Dr. Elizabeth Yahl-Kuffner Nature Preserve has re-opened to the public! Thanks to generous donors, a brand new boardwalk has been installed to enhance accessibility to all hikers. In the coming weeks, new benches, trail signage, and informational kiosk will also be added to further improve this amazing Auglaize County park. Our park lands are open to the public from dawn to dusk, 365 days a year. Pets on a leash are welcome, but please clean up after your pet. Kuffner Nature Preserve is located at 14840 County Rd 66A, St. Marys, Ohio.
