Olympic Peninsula, WA - all NFS sites 21-foot limit?

"National Forest" is one thing, "National Park" is another.

But in both cases, little has been done in the past forty years or so to enlarge sites to accommodate Big Rigs. When the Public places were set aside, no one anticipated that folks would be driving what amounts to a Greyhound bus with two passengers in it to a so-called "campground"

I live here and have camped at them all...my advice is to make reservations at one of the Private Campgrounds that have sprung up to accommodate bigger rigs.
