Lower Hyalite - Sourdough Loop Professional Review and Guide

"This ride is located 8 miles south of Bozeman in the foothills of the Gallatin Range. Highlights: A non-technical loop ride in the mountains; an exhilarating 4-mile descent on closed logging roads; many options for side trips or extended loops. Tread: 8.4 miles on paved road; 3.9 miles on gravel roads open to traffic; 8.9 miles on closed logging road, some of which is reverting to double- and singletrack.

Watch for traffic on all open roads; yield to other trail users, especially on popular doubletrack in Sourdough Canyon. Watch for other trail users. Ride in control and yield to all hikers and equestrians."
