There are few campgrounds near Umatilla, OR and when we were there several public facilities were closed. We very rarely ever stay at RV parks but it was getting late and we had just driven on 395 through the snow and fog. There were tent sites available for $20 so we checked in at the office to be assigned our spot. Unfortunately, someone was there who hadn’t paid so we were told to choose another. They had the better spot but we just took another as they were in a tent and probably freezing to death.
During the night, some people camping in their truck would start the engine every hour to keep warm plus the truck traffic over the I-82 bridge was noisy. This was in late October 2020 during a cold snap.
The only good thing is that the flush toilets were clean and you could take showers using coins. There was a key code for the bathrooms and free WiFi. There were shade trees and a nice lawn area, but the area with hookups was further from the traffic.
We would probably not stay here again.
