Sand Creek Regional Greenway
The Sand Creek Regional Greenway is a beautiful 14 mile long path. Terrain ranges from paved to soft and sandy, though rideable on any bike. 
Throughout the greenway, riders will pass through industrial sections, a few neighborhoods and parks. Along the way are Bluff Lake Nature Center, Sand Creek Park, and Star K Ranch. Just speaking from personal experience riding this trail, I have encountered a great deal of wildlife here including owls, deer, rabbits and foxes. This is one of my favorite rides with my kids. 
Sand Creek also goes into the High Line Canal trail if riders want to elongate their ride.
