We are at the Older Mill in Umatilla and it is everything they advertise and more. The problem you will have is that there is a waiting list to get in, but it is worth the try to get on the list and keep checking to see if cancellations. When you come down the first time even if you don't get in then you should come and take their tour. They are adding more sites and we loose people all the time for one reason or another. The sites here are larger than most places and you are welcomed by all. As Dream Chaser said they are pushing for all six by six, but with that said you will not find a better park for the price.
