Tucson's "Turquoise Trail" history takes you to Old Town Artisans. The square block—now home to connected adobe rooms full of gifts, art and other regional treasures—once held stables within Tucson's Presidio, built in 1776. Today, the patio, dense with olive trees and native plants, speaks more of Tucson's regional charm and storied gastronomy than its history. Listen for the birds, and the cooling trickle of the hidden fountain. On Sundays, there's music.
