The Los Caminos Antiguos Scenic Byway stretches around the Great Sand Dunes National Park and winds its way down to the state boarder with New Mexico. Its name means “the ancient roads,” and was given for its part of the 16th century Spanish territorial expansion. The San Luis Valley that the byway traverses is filled with some of Colorado’s oldest and richest history. Visitors can explore the sand dunes and then continue along and explore the Hispanic culture and sites all throughout the valley.
