Sugarloaf Mountain, one of the closest offroad trails to Boulder, offers stunning views of the snowcapped Rockies to the west. The drive gradually winds through aspen and lodgepole pine forests with lovely views of the area's valleys and gulches. The hills burst with gold color when the aspen trees transform in the Fall. This captivating journey offers adventurers a glimpse into the area's rich mining history. Originally part of a narrow-gauge railroad bed that served the mining communities of the late 19th century, this trail now beckons hikers, bikers, and explorers to traverse its scenic track.
