Green Mountain Summit Via North Vista Trail is a 6.5 mile lightly trafficked out and back trail located near Crawford, CO that features a river and is rated as moderate. The trail offers a number of activity options and is accessible from May until October.
Awesome trail in the Black Canyon of Gunnison National Park ($15 for a week pass). No crowds on a Wednesday in August. The views are spectacular the entire way. All-around easy trail but definitely is the longest/most difficult trail on either rim (non inner-canyon trail).
