The 5 parking places on Brannen Circle at Lone Tree Road provide the easiest access to Sinclair Wash Trail and the Flagstaff Community Labyrinth. Additional parking can be found on residential streets off of Brannen Circle. Sinclair Wash Trail is more interesting to the east because the wash has carved a 50-ft deep canyon, the vegetation is dominated by native trees, shrubs, & herbaceous plants, and unusual birds can be seen here. Some of the canyon’s plants are rare in other parts of Flagstaff, including willows, Arizona honeysuckle, and wild hops & wild grape. Please stay on the trails and help protect these rare plants for future generations. Poison ivy (photo) is one of the most abundant short shrubs in this canyon, and often grows intermixed with the other rare plants. Leaves of three – let it be!
