Hellbender Preserve is a 15.43 acre site that contains the Buckeye Grove Loop Trail. The site was named after the state endangered, and Ohio's largest amphibian, the "Eastern Hellbender." Eastern Hellbenders live in the clean, high-quality waters of Jelloway Creek and the nearby Kokosing State Scenic River. The preserve is accessed from the Kokosing Gap Trail in Howard. The nature trail offers streamside access to beaches along Jelloway Creek. Buckeye trees are numerous throughout the site.
