The Door County Coastal Byway (Hwy. 42/57), a Wisconsin Scenic Byway, stretches over 66 miles, beginning just north of Sturgeon Bay, northward to the ferry dock at Northport, and then south through Jacksonport back to Sturgeon Bay.
The route offers a range of resources and activities with scenic vistas of Lake Michigan, the Bay of Green Bay and Niagara Escarpment bluffs, as well as dense forest, agricultural lands, and quaint shore-side towns and villages.
The Door County Coastal Byway features three state parks, ten county parks and several lighthouses. Towns and villages along the way offer shops, restaurants, galleries, music, theater, festivals and events, orchards, boating, fishing, hiking, biking, golfing and year-round recreational activities.
The Wisconsin Scenic Byways program is a cooperative effort between local communities and the Wisconsin Department of Transportation to identify and promote state highway corridors with scenic and/or historical attributes that provide travelers an enjoyable visual, educational and recreational experience.
