Because Arlington is a member jurisdiction of the Northern Virginia Regional Park Authority, park admission is FREE for Arlingtonians (and Alexandrians, and Fairfaxians, and several others) – just show your driver’s license at the entrance.
If your kids are old enough to resist the impulse to leap overboard just to see what would happen, you can rent one of several kinds of human-powered watercraft (including some pretty funky pedal boats) or bring your own craft and put in at the boat launch for a small fee.
Pohick Bay is 25 miles south of DC, off Route 1 near Lorton. To make a day of it, combine your trip with a visit to one or both of its close neighbors: Gunston Hall, historic home of our buddy George Mason; and Mason Neck State Park.
