We are wanting to ride from Portland,Or to Des moines, Iowa this upcoming June. Would love some insight to a great route.
For the final 60 miles into Des Moines get on the paved bike trail at Jefferson, about 60 miles NW of Des Moines. Trail takes you right to downtown Des Moines through the western suburbs. As for the rest of Iowa, South Dakota, Nebraska, just get a state road map and pick out some lesser roads. Most of the non interstate roads in the western states are lesser traveled.
