I see you are an Escapees Member. Go to Days End and download the latest list of free or low cost camping sites. There is a nominal charge of $15 for the download. If you provide several reports back to Days End each year the list is free for the next year.
I suggest staying at the Olympic NP campgrounds, especially, Hoh Rain Forest, and South Beach or Kalaloch CG's. Make reservations for Kalaloch early, it stays full much of the summer.
It is much nicer staying in the NF campgounds. You can see the sunset on the ocean from your front door, attend the ranger programs in the evening. Many times there are very informative day programs available, like ranger guided hikes. Not that you can't drive to take the hikes, but why drive round trip when you can camp right were the hike will be.
