Roswell to Nogales: Epic Southwest Road Trip Guide

This route crosses the Continental Divide near Lordsburg, NM, at an elevation of 4,595 feet—a subtle but pivotal watershed. The drive spans 630 miles, roughly 10 hours without stops, yet the landscape shifts from the Pecos River valley to the Sonoran Desert.

Historically, this corridor follows the path of the Southern Emigrant Trail, used by pioneers and the Butterfield Overland Mail. Today, US-285, I-10, and I-19 form the backbone.
