Planning a scenic drive in Maryland
Start with the headline routes. Maryland’s All-American Roads — Historic National Road – Maryland, Harriet Tubman Underground Railroad Byway — are the obvious place to begin. Check seasonal conditions before you travel — mountain and back-country byways can close in winter. For overnight stops along the way, see our Maryland campgrounds map, and for a different pace try the Maryland cycling map.
Route data comes from the US Department of Transportation scenic byway layers at geo.dot.gov, harmonised into a single dataset. It reflects what the transportation agencies publish and may lag local designations. Routes show the mapped corridor and are for planning only — check current road conditions before you travel.
