The Flambeau Trail loop head is on the East side of Park Falls. North off hwy 182 on Hoffman lake Rd. Use Price county trail map.
The Dead Horse Trail head is North of Loretta off County road GG heading north. Use Tuscobia ATV map. Any bar or gas station will have them.
I have a cabin up there but you might google price county motels or campgrounds. The Flambeau loop has more places to stop for food and drinks and fuel. The Dead Horse Trail is pretty remote, only stops are in Loretta or Clam Lake for fuel and Drinks a food.
The Flambeau River State Forest trail is nice also, Starts at Hwy E 1.3 mile west of Pine Creek Rd. on the south side,has a huge parking lot. You can run it south then gravel road it east to the Georgetown trail and go north. A few miles west on Hwy W you pick up the Flambeau River trail again and head North to the trail head. It is a nice loop but don't forget to stop at OXBO resort to get a cowboy burger.
