The Greenbelt Hike/Bike/Equestrian Trail is located between Lake Ray Roberts and Lake Lewisville. Through a joint project with the Army Corps of Engineers and the Cities of Denton and Dallas, a trail has been established where outdoor enthusiasts will be able to hike and bike the entire length (about nine miles) of the Elm Fork of the Trinity River.
