Bitterbrush Trail on Hall Ranch Open Space

Northwest of Boulder, Colorado lies the Hall Ranch Open Space, part of the North Foothills Open Space complex. Both Hall Ranch and Heil Ranch are included in this system, and both areas have incredible mountain bike trails that are now connected by a bike trail.

The Bitterbrush Trail and the Nelson Loop Trail are both on Hall Ranch Open Space and are about a mile and a half from Lyons, Colorado on highway 7. The two trails make up a lasso trail (sometimes also called a lariat trail) with the Bitterbrush Trail forming the rope handle of the lasso and the Nelson Loop Trail forming the actual lasso.

These trails are fairly steep in spots, and they are studded with outcropping rocks and tree roots along the trail. While these obstacles make the trail fairly difficult, they also make it the ultimate roller coaster ride for seasoned mountain bikers.
