BLM campground near Frenchglen, at the western base. It’s a nice one. They even mow the grass.
It’s a long, gradual climb on an excellent unpaved road. All the way to the top. I waited for the sun to be just high enough that it wouldn’t be in my eyes as I drove. I had the road mostly to myself. The early bird gets the empty road. And first choice of photo locations.
That light patch in the distance, showing just above the ridge, is the Alvord Desert. Yes, there are deserts in Oregon.
