If you like beach sites, we just came from doing the 101 all the way from Coos Bay to the end near Olympia. In Charleston (Coos Bay), the Oceanside RV park has some sites about 20 feet or closer to the sand dunes by the beach. Hike thru the flora on the Dunes for about 75 feet and you are on the best beach I have seen on the West coast. I asked it the county or state cleans it, as there is a park nearby. They said no - it just stays clean. No seaweed anywhere and the sand was almost like in Florida - not quite white but close.
Also, further north at Depoe Bay, there is the Sea and Sand RV Park. It is on a little cliff about 40-50 feet high overlooking the beach. Wonderful views. If you stay there, pick a middle row near the beach. The closest to the beach (all backins or pullins) actually faces away from the beach unless you have a Class A. If you take the middle level, you back in and your back window will overlook the ocean.
