It's really quite simple; you just connect two good trails and you get one great trail. Here are some examples:
|C & O Canal trail connects to the|
GAP trail, the Western Maryland Rail Trail,
and the Mount Vernon Trail.
- Silver Comet Trail + Chief Ladiga Trail = Super Trail
- New Santa Fe Trail + Pikes Peak Greenway Trail = Megatrail
- GAP trail + C & O Canal Towpath trail = Mighty Trail
