Historic Route. The historic trail route crosses the Mexican border and enters the United States in the City of Nogales, proceeds north along the Nogales Wash for several miles to its confluence with the Santa Cruz River, and then closely follows the Santa Cruz River through Santa Cruz County.

Federal Components 
Tumacácori National Historical Park, including San Cayetano de Calabasas and Guevavi (NPS)

Historic Sites
Camp #14, Tubac Presidio State Historical Park. (AZ)

High Potential Route Segments
Privately owned trail between Tumacácori and Tubac managed by the Anza Trail Coalition of Arizona. The ultimate goal is that the Coalition would accept the easement and would develop and maintain the trail. The Coalition is working with other landowners to extend the trail throughout the county.

Interpretive Sites
Camp #13, Las Lagunas, north of St. Andrew church in Nogales.

Recreational Trail
The Santa Cruz County Comprehensive Plan recognizes the Anza Trail and provides ultimately for the development of a hiking and riding trail linking several linear parks along the Santa Cruz River. Calabasas Park, opened in the spring of 1993, is the first developed by the county along the river. The final goal is the protection of the Santa Cruz River corridor. This proposed river trail would closely parallel the historic route from the confluence with Nogales Wash north through the county. The proposed Mission Trail from Guevavi to Tumacácori, a part of the proposed county route, would be a trail link to the Juan Bautista de Anza National Historic Trail.

The potential of the Nogales Wash to become a recreational component of the Anza Trail should be explored. Trail planning could consider the issues of riparian corridor protection and water quality in this wash.

For bicyclists, a frontage road along Interstate 19 (I-19) could be marked as the historic route. The NPS will encourage a continuous bicycle route through the county as work is performed on I-19.

Auto Route (marked) 
I-19 closely follows the Nogales Wash and the Santa Cruz River and is within the historic trail corridor.
