A 62-mile, improved railbed trail that connects Ashland to Superior. Spanning the three counties of Ashland, Bayfield and Douglas, the Tri-County Corridor Trail is a scenic link between Superior and Ashland. Most of the trail is crushed limestone and open to a wide variety of uses. (If asphalt is what you're after, head east to Ashland's Central Railyard Park for a short, smooth trip on the trail's 3-mile strip of pavement.)

Bicyclists, hikers, and equestrians share the trail with all-terrain vehicles from spring through fall, while snowmobiles dominate in winter. Signs specify that motorized users keep to one side of the trail, which keeps the surface suitable on the opposite side. However, increased ATV traffic, especially on weekends, can make for a bumpy bike ride in some sections because of sporadic patches of loose gravel.
