St. Marys State Park offers scenic woodlands, diverse wildlife, and access to the St. Marys River, providing visitors a place for hiking, fishing, and camping in western Ohio.
St. Marys State Park is located in Auglaize County, Ohio, along the banks of the St. Marys River. Encompassing over 180 acres of primarily forested land and river wetlands, the park features a mix of floodplain hardwood forests, open meadows, and riparian ecosystems. The St. Marys River, a major tributary to the Maumee River, runs through the park and is a focal point for fishing and wildlife observation. The park’s landscape reflects much of the natural environment typical of northwestern Ohio, supporting species such as white-tailed deer, beaver, various songbirds, and occasional waterfowl visitors. Originally settled in the 19th century, the area served as a location for river trade and farming before its establishment as a state park focused on outdoor recreation and habitat preservation. Visitors commonly enjoy hiking along marked trails that wind through mature forests and streamside environments. Fishing is popular along designated river access points, particularly for warm-water species. The park also has multiple picnic areas and a campground offering a blend of modern and rustic camping opportunities. Seasonal activities include bird watching in spring and fall migratory periods and cross-country skiing during winter months. St. Marys State Park holds value not only as a recreation destination but also as an important green space protecting river corridor habitats in a predominantly agricultural region. Its relatively small size makes it accessible for day visits while still providing opportunities to experience Ohio’s native flora and fauna.
