The Custis Trail is a hilly 4.5 miles (7.2 km)-long shared use path in Arlington County, Virginia. The asphalt-paved trail travels along Interstate 66 (I-66) between Rosslyn and the Washington & Old Dominion Railroad Trail (W&OD Trail) at Bon Air Park.

This trail stays mostly to the outermost trails connecting at least a portion of every trail in the park. The tent loop section off of Lakeshore and before the paved area can be hard to find due to a lack of markings, but it usually only takes a couple of extra seconds if you do get off trail there.
