Having a bike in D.C. is great fun. If you have one already, you’re all set for free fun. If not, check out this information on renting bikes for a day. Start at Big Wheel Bikes in Georgetown if you don’t have a bike because here, you can rent a simple bike for $25 per day. If you do have a bike, I’d recommend starting at Gravelly Point in Arlington, along the Potomac, because the parking is better and the views are nice.
The Mount Vernon Trail goes all the way to Washington’s Mt. Vernon estate but for those seeking a leisurely ride, Old Town is a great turn-around point. Along the way, stop for a packed lunch at one of the memorials.
