If you are staying in the Klamath Crescent City area, Kamp Klamath I can say is probably one of the most desireable campgrounds in the area. In the RV section there is some separation. They all have fire pits and picnic tables.
In the other parts of the park there is even more separation and more of an “in the woods” feel.
The staff is very friendly and helpful. They will go out of their way to see that you get what you need. The campground is also very pet friendly.
