Greenways are protected corridors of open space along natural features, such as streams or ridges, or along man-made features such as abandoned railroad corridors or scenic roadways. Greenways protect important community resources, such as historic sites and streams, and connect these resources to each other and to parks, schools, and neighborhoods. They also provide recreational opportunities such as hiking, biking, canoeing, walking, jogging, and fishing, and provide a place for people to enjoy nature.

The City of Huntsville adopted a Greenway Plan in 2006 to guide the development of greenways throughout the community. When complete, the system will include over 180 miles of interconnected trails, including canoe trails, pedestrian/bike trails, and hiking trails. Currently, there are more than 27 miles of existing greenways and trails located throughout the Huntsville area.
