The Tracks Across Borders Byway invites travelers to take a scenic, historic journey between Durango, Colorado and Chama, New Mexico — tracing the old narrow-gauge rail corridor of the Denver & Rio Grande Railroad. This 125-mile byway offers a rich mix of natural beauty, cultural heritage, and railroad history: visitors can explore Native American sites, ride vintage trains, view sweeping western landscapes, and stop at points of interest like national monuments, state parks, and local communities steeped in history.
Operated as a nonprofit and officially designated a scenic and historic byway in both Colorado and New Mexico, the Tracks Across Borders Byway also provides a free companion mobile app for self-guided tours with audio highlights and geo-alerts. The route is best experienced spring through fall, with advisories about road conditions and vehicle requirements for some stretches.
