The iconic Eisenhower Tunnel. The spooky Gold Camp Road Tunnel. The historic Moffat Tunnel. You know all there is to know about these famous Colorado structures, but did you know that the Centennial State is also home to some tunnels that are completely natural? Take for instance these beautiful, natural, and rocky tunnels that few people know even exist:

Incorporated in 1883 was that of the old Colorado Midland Railway; Colorado’s first standard gauge railroad that was located over the Continental Divide.

Running from Colorado Springs to Grand Junction with stops in Leadville and Glenwood Springs, the Midland was once a vital part of the Colorado economy in that it assisted in shipping silver and other valuable ore.

Like many turn-of-the-century railroads, the Colorado Midland was abandoned in 1918, leaving behind several employees and friends of the line.

While railroads folding is a tale as old as time, the story of the Colorado Midland is different, as it left behind not only stories, old depot buildings, and railroad cars, but also beautiful, all-natural tunnels, like these at Chaffee County Road 371 in Buena Vista…

Also constructed in 1887, the old Hagerman Tunnel sits at an elevation of 11,528 feet, which broke the then-record for the highest tunnel ever built.
