Along the coast, there are many options for lodging, but in my opinion there are only two real choices -- top-notch b&b''s with ocean views, or camping at the state parks. The Oregon Coast at times seems to be 100% state park land, and most of them have camping. At less than $20 a night (that includes site fee, parking, tax and park usage fee), camping rules!
At Beachside (built to open in 2000), we were a short walk from the beach: we could hear the waves from our tent. The beach itself was wide, yellow and clean (we went for walks every day). The facilities were brand-new and clean, and when I wanted hot water, I could get it. (That''s a biggie as the beach sites get very chilly at night.) If you are not a tent-camper, you can also get RV-ready sites as well as Yurts, which are kind of glorified teepees with beds and kitchenettes, and actually quite comfortable and economic. Our site itself was clean and pretty. The foliage around us was green and deep. The location of this campground is convenient as well -- it''s near Waldport (we went to go see a movie one night), the Yaquina Bay Lighthouse, Point Perpetua and there is great freshwater fishing a bit inland.
