The coast is a must. Gold Beach, Coos Bay, Newport, Austoria would all be on my list. Also Multnomah Falls area just out of Portland offers some light hiking with great views of the Columbia River. I will post pics when I get home.
I agree. You should definitely check out Multnomah Falls if you enjoy hiking with some of the most beautiful scenery in Oregon. Also, Portland is a great place to get some good food and and culture.
I have to reccommend the area surrounding Bend and Redmond. There are plenty of awesome fishing/camping/hiking places on both the crooked and deschutes rivers. There is a campground called "trout creek camp", which my family has gone to yearly for many years. There are mesas to climb, five miles of fishable river, and the campground is beautiful. Beware of rattlesnakes though.
