Definitely check out Florence, Oregon. It's about an hour south of Newport. It may have changed, since I haven't been there for a long time, but it used to be much less touristy. It has a nice downtown right at the mouth of Siuslaw River, great beaches that are never crowded, and just north of there IIRC, there is a botanical garden specializing in carnivorous plants. It's also less than an hour inland to get to Eugene, if you have any interest in checking that place out. I worked one summer at the little coffee shop downtown just inland from the bridge. It was a total small-town community hub that all the locals hung out at, and had great coffee too. Very laid-back place with beautiful surroundings.
