Route: Coal Creek Trail (CO)

Soft-surface (mostly gravel) trail that connects 4 towns (Superior, Louisville, Lafayette, and Erie), many parks, with beautiful sunrises/sets and neat wildlife like coyotes, bald eagles, owls, vultures, and an occasional bobcat.  If you're a runner in the general vicinity, you have run part of this trail; but doing it all at once is a fantastic experience as well.
