Old Woman Creek is both a National Estuarine Research Reserve and an Ohio state nature preserve, protecting one of the state's better remaining natural estuaries. The mix of creek, marsh, and Lake Erie shoreline makes it a good place for birding and quiet walks.
The reserve has parking, paved trails, restrooms, drinking water, and observation areas when the entrance gates are open. It is a solid nature stop between Sandusky and Huron, especially if you want a break from amusement-park crowds.
