There are a large number of wonderful places to see in Oregon, but if you are into mountains at all then might I suggest stopping off at Mt. Hood.
June through September are the ideal months, though there is of course skiing through the winter.Activities include hiking, camping, fishing, and berry picking. There are many, many miles of trails to hike, ranging from beginner to very advanced. Opportunities to see wildlife in their natural habitate abound.
Of course this isn't the only mountain in Oregon, but it may well be the most famous. I do recommend you check it out if ever you get a chance.
