Alexandria has an extensive trail system that connects George Washington’s Mt. Vernon home with D.C.’s Georgetown neighborhood and beyond. An extremely popular activity with locals and visitors is to grab a bike and ride on the Mt. Vernon Trail. This relatively flat trail can be picked up in Old Town with two options: a 12-mile ride south to the Mt. Vernon Estate (it’s a bit hilly) or a ride north past National Airport (and right under the jumbo jets landing there) and along the Potomac River, with a great view of the Capitol, Washington Monument, Jefferson Memorial, and Lincoln Memorial.
Bikes can be rented from Bike-n-Roll in Old Town, right off the bike path. Bikes are $35 for the day, but for only $5 you can ride one way between shops. If you’re in decent shape, a ride from the shop in Alexandria to the shop in D.C. at Union Station would be a great way to see the sites!
