A few miles from La Pine, this 5-site campground sits along the Deschutes River in the Deschutes National Forest. The campground is pretty bare-bones in terms of basic amenities; there is no tap water available and there are two pit-toilets. There is also no cell service. However, the campground does provide great access to the river and even has a cement boat ramp for easy access.
Each campsite has a picnic table, a fire pit, provided firewood (at least when I was there), either a pull-through or back-in parking space, and a view of the river. If you make a reservation (which are required for at least 2021), the camp manager will post this on the site marker so that your site isn’t taken by another party. The campsites themselves are somewhat dusty/sandy, but are otherwise clean. Sites 1-2 and 4-5 are right next to each other, whereas site 3 is probably the best site for privacy.
One more thing to consider if you are staying in a vehicle is that not all of the sites have flat parking spaces. I was able to make something work with my van in site 1, but site 2 would have been unpleasant for sleeping in a van. Sites 4 and 5 seemed to have the flattest parking.
