Bikers can take advantage of networks of bike trails including Greenways and Blueways and designated Rails-to-Trails paths. Networks of bike trails can be found in national parks like the Cumberland Gap National Park in Virginia or in Arizona's Apache National Forest. Tennessee's Greenways and Blueways are safe and fun trails for road biking and exploring the area's countryside and lakes.
Michigan's participation in the Rails-to-Trails system, where old railroad tracks were converted into bike paths, has created a network of bike trails perfect for exploring the state. Mountain biking on logging roads, jeep tracks, and on uncharted areas in state's mountainous regions can be a thrilling way to explore areas unreachable by car.
