The Ohio River Islands National Wildlife Refuge protects more than twenty islands scattered along a 392-mile stretch of the Ohio River, and it's home to a diverse range of plants and animals, including endangered freshwater mussels. Hiking, birdwatching, and wildlife spotting are among the most popular activities here, and the best trails start near St. Marys and Williamstown. Before exploring the refuge, visitors are advised to stop by the Refuge Visitor Center in Williamstown to learn about the landscape and the creatures who call it home, but interpretive signs can be found along some of the hiking trails as well.
