Forty miles of dunes, lighthouses, and wild Atlantic shoreline along the Outer Cape
This one gets you out of the streets and into the open. Five stops over 37.4 miles, about an hour and a half of driving. Each one starts talking the moment you reach it, so you can keep your eyes on the street instead of a screen.
There is no start time to make — walk it in one go, or leave the rest for another afternoon.
