The Presidio Trail, also known as the Turquoise Trail, is a downtown walking trail connecting more than 25 historic downtown sites. The bright turquoise line to the west of the Joel D. Valdez Main Library is the Presidio trail. The trail is about 2 ½ miles long.
Brochures about this trail are available at the Metropolitan Tucson Convention and Visitors Bureau, 100 South Church Avenue, and at various hotels and restaurants, and online at: https://tucsonpresidio.com/turquoise-trail
Historical downtown locations are connected by a turquoise-colored line painted on the sidewalk for most of the length of the trail. The 25 sites are located in a loop around Downtown, from the Presidio Wall south to Carrillo Elementary School, then northeast to the Hotel Congress and northwest to finish at the Telles Block, which is now Old Town Artisans. The bright blue turquoise color was chosen because it was the only paint that the City of Tucson had available that did not signify a water line or underground utility.
