Waco to Marfa: Epic Texas Road Trip Guide

The 450-mile journey from Waco to Marfa crosses the heart of Texas along US-84 and I-10, a route that transitions from the lush blackland prairies of Central Texas to the high desert of the Trans-Pecos. This route roughly follows the path of the Old San Antonio Road, a historic trail used since the 18th century.

One of the most unique features of this drive is the section between Junction and Fort Stockton, where you traverse the Edwards Plateau—a vast, karst landscape with over 3,000 caves, including the famous Caverns of Sonora. This geological wonder is a must-see for any traveler.
