Santa Fe to Fountain Hills: Desert Road Trip Guide

The route from Santa Fe, New Mexico to Fountain Hills, Arizona spans 686 miles along I-25 S and I-40 W, with a brief detour on AZ-87 S. This drive takes roughly 10 hours without stops, but the journey itself is a story of geological upheaval and cultural collision. The Camino Real de Tierra Adentro, a historic trade route, once connected Mexico City to Santa Fe, and parts of I-25 follow that same corridor.
