No Amenities but Close to Town
I have stayed here a couple times on motorcycle trips around Oregon. There are lots of sites that have been used and it's a great place to spend a night or two. It's close to Sisters so you can grab what you need.
You're close to the Rodeo grounds so you can hear what's going on if there are any events there. Overall, great free place to camp if you're in the Sisters, OR area.
