Leif Erikson Drive - Firelane 1 Professional Review and Guide
"Portland’s Forest Park is a wilderness setting in a world-class city providing a spectacular loop that combines both gravel and dirt roads and pavement. You’ll ride for 6 miles on Leif Erikson Drive, winding through a landscape of hardy bigleaf maples, dark green sword fern, Oregon grape, and red elderberry.
After a short paved section, you’ll ride a steep descent on Firelane 1, where you may have to dodge a few boulders, roots, and rocks. Nowhere else can you be so close to a city, yet feel so far from it all. Trail surface: 0.9 mile of singletrack; 11.2 miles of gravel and dirt roads; 2.9 miles of paved road."
