Road out to Condon and Service Creek from Biggs corner is outstanding. The Deschutes Rec Area is a bike trail worth riding.
Washington’s side is rideable. The twisty sections are sports car country. Nearing Portland the road may be more party goers than serious drivers.
The northside drive with a sports vehicle is outstanding river side driving esp in the fall when the Alder turn yellow.
