The White River BLM Campground is north of Maupin along the Deschuted River BLM access road. I think there's about 5 sites. These sites are all located along the Deschutes, between Maupin and the 216 highway. I think the sites were $16/night. 

The sites are pretty basic, with vault toilets and no running water. There is a picnic table and fire ring at each site.  The highlight is the amazing river access and views. Fishing and rafting are the main activities here. 

I loved the sound of the Deschutes as you fall asleep.
