Deep River County Park offers a mix of history, natural beauty, and pure fun within its 1,200-acre site. In 1837-38, John Wood built a sawmill and gristmill here along the Deep River, creating Lake County’s first settlement industry. Park visitors can explore Wood’s Grist Mill and the neighboring Deep River Visitor Center, housed in a 1904 church. Trails lead from here to lovely natural areas throughout the park. Visitors can fish, hike, ski, horseback ride, picnic, and take hayrides (autumn). The park is also home to the Deep River Waterpark, a regional attraction that draws more than 200,000 visitors a year.
