We stayed at the KOA while overnighting in Klamath Falls. It's in the "Journey" category, as in it's not a destination RV park.
The park is sort of a pain to get into. One must make a sharp right turn into the drive, and then an immediate second sharp turn in the parking lot. It's doable, as long as no one is blocking the arc of your turn.
If someone is at the other pump, it will make the turn difficult.
Interior roads are paved, sites are gravel and fairly unlevel. Power is good. Water pressure is good. Verizon is pretty dang slow, it takes awhile for Google maps to load. They do lead you to your site, which is good. No data on restrooms or laundry. There are trains, with loud whistles, late at night.
We're in site 27 which is a pull through, and we have a clear shot at the southern sky.
It's ok for an overnight, and we would come back here.
