South Boundary Professional Reviews and Guides
"This is an incredible tour of the Sangre de Cristo Range that takes you across ridges, valleys, and several peaks, through gorgeous conifer forests and incredible stands of aspen. This ride is at its very best in the fall when the aspens along this route turn every shade of yellow, gold, and fiery orange. Besides being a wonderfully scenic tour of New Mexico’s Rocky Mountains, this is also one of the state’s best mountain bike rides."
