Tucson:
A seven mile stretch of Anza Trail exists a few blocks west of downtown Tucson. It runs from West Silverlake Rd (29th St.), north along the Santa Cruz River, to Columbus Park at Camino del Cerro Blvd. The official Anza Trail route is on the raised cement berm on the west side of the river. This trail is paved from Silverlake north to Grant. North of Grant the trail becomes packed earth and gravel. The trail is continuous and dips safely under major cross streets. Bridges span the washes.
A second 1.5 mile section exists between Ajo and Irvington where groves of trees have been planted, including one dedicated to Anza.
Both trails are open to foot and bicycle traffic.
Equestrians can ride horses in the river bottom when rain doesn't threaten. During monsoon season the dry riverbed can fill with water in seconds.
