We spent some time driving around the Sisters area looking for a spot with a view.  Found a beauty!  The area is large enough for several rigs, including large ones.  There were 2 established fire rings and we could tell the site gets used through the summer!  (or maybe fall/hunting)

However, in early May we had it to ourselves.  

Some of the surrounding area has experienced previous forest fires, which was actually a benefit in this case.  It opened up views of the North and Middle Sisters.  Small tracks/roads criss cross the surrounding area that is covered in shrubbery and small trees finding their way back.  The vistas include large trees, so it's not barren by any means.  The camp site, as you will see, is surrounded by large ponderosas.  Lovely peaceful spot.  Perfect for sitting and gazing, walking, hiking, biking, horseback riding and likely off roading.  Please don't take my word for where these things are allowed.  Do your research to make sure who's land you're on...

My maps showed overlays of National Forest land all around, although some private and BLM land to the east.
