Avoid the cities completely, come into Oregon down the Columbia River Gorge, stop at Multamona Falls, go north on I-5 to Longview WA, Cross the Columbia there, or stay in WA to the 4-mile long bridge over the river into Astoria.
In Astoria go to the column climb it and take in the view, there is also a fort to sea hiking trail from Lewis and Clark Natl. Park, a herd of elk can sometimes be seen in Fort Stevens and where the Columbia River meets the sea was worth the time.
Did the long haul trucker thing for years, The Colombia River Gorge is
one of the most scenic drives in the country. One of the very best
from an interstate.
