an interesting historical park is near Astoria
the place where Lewis and Clark spent a winter.
it is a national park Lewis and Clark National
Historical Park, Fort Clatsop National Memorial ...
located approximately 5 miles south of Astoria, Oregon. ...

most state parks in Oregon have great camping facilities..
including Yurts, and tipis and even old covered wagons for
overnight stays...www.oregon.gov/OPRD/PARKS/index.shtml

if you go down the coast of washington and into Oregon via the
bridge by astoria it is a pretty (if not very fast) way to go.

another orgeon tourist trap is the cheese factory in Tillamook.
better yet is the smaller one just south of there--Blue Heron
where you will find cheese mustard, wine, and other goodies.
