We're visiting for the first time, and I'm not sure how much to try and do. We're flying in and out PDX, in on a Sunday night, out on Sat am. With 5 full days, is it too much to try and visit Columbia River Gorge, Willamette Valley, Bend, Ashland wineries, and the coast? We want to take in the natural beauty of Oregon, maybe a short hike or something to enjoy the outdoors, and visit the wineries of course. I thought we might take off first thing Monday am, then wrap up with a little time in Portland on Friday. Another option to the southern wineries would be to head north and take in some of Washington's. As far as driving distance and scenery, is there a better option on that?
