D11. 28L is a free, non-reservable primitive campground located on the banks of the Deschutes River with stunning canyon views and access to the Lower Deschutes River Trail.

The site offers vault toilets and allows campfires, but has no other amenities—visitors must bring their own water and supplies. Summer is the best season to visit (70-90°F), though be prepared for hot, dry conditions and bring plenty of water.
