Sinclair Wash Trail

Flagstaff Urban Trails System (FUTS)About the Trail

Sinclair Wash Trail is Flagstaff's longest urban trail is also one of its most varied. 

Traveling north from Fort Tuthill County Park, the trail passes through a rural area marked by open grasslands and patches of Ponderosa pines. Further north, the trail follows the Sinclair Wash through the more urban setting of the Woodlands Village commercial area. Turning east, the trail passes under I-17/Milton Avenue, enters the campus of Northern Arizona University, and winds along a forested hillside across the south end of the campus.

East of Lone Tree Road, the trail parallels the Rio de Flag through a verdant, limestone-walled canyon. In this section there is an atmosphere of quiet and solitude, even in the middle of Flagstaff. Two small seasonal ponds at the eastern end attract a variety of water birds and other small animals. The trail ends at its intersection with the Arizona Trail.
