Betasso lies due west of Boulder. It can be accessed by car by heading up Canyon then Sugarloaf Road to the main trailhead, or by riding to the Canyon Link trail (starts just before the tunnel up Boulder Canyon) or the Four Mile Connector (about 3 miles up Fourmile Road).
This is the only place in Boulder County that has limited access based upon the days of the week. Betasso is closed to cyclists Wednesdays and Saturdays. It’s also the only local trail that has directional rules for cyclists, with the cycling direction on some trail changing every two weeks. Always mind the closed days and directional arrows!
There are two loops in this system: The Canyon Loop and the Benjamin Loop. Both are relatively smooth with the occasional rock features to ride over, making the trails more beginner friendly. However, keep in mind that these trails are largely built on side slopes and the exposure makes them feel more technical than they really are. Riders venturing out to Betasso will get great views of town to the east, mining activities across Four Mile Canyon, and the revegetation of the recent Four Mile Fire to the west.
In addition to these loops, the Canyon Link and Fourmile Link connect to their respective roads. The Fourmile link is ‘in tune’ with the rest of the trails. The Canyon Link is steeper, rougher, and more narrow than the rest of Betasso, and offers a place for those seeking larger challenges.
