Sinclair Wash Trail is a 5.9 mile moderately trafficked out and back trail located near Flagstaff, AZ that offers scenic views and is good for all skill levels. The trail offers a number of activity options and is accessible from April until October.
I actually usually bike this trail several times a week. It's well maintained and cyclists, hikers and joggers share it amicably. Once you get out to Ft. Tuthill fairgrounds there are a number of other trails encircling the area, so you can expand your adventure accordingly. The trail is part of Flagstaff's Urban Trail System (FUTS).
