This is a beautiful park! The lower-level sites right on the McKenzie River are great! Our trailer is 24' long, and we would have found it difficult to get into some sites. Site 16 is especially lovely as it is at the confluence of Olallie Creek and the McKenzie River. We found it easy to back our trailer into this site. We would make a point to staying here again--such a peaceful place. We camped at Olallie at McKenzie Bridge in a Travel Trailer.
