River Rim RV Park has about 27 sites. Their rates were excellent, just $26.75 per night and all hook ups.
The campsites and roads are gravel with concrete pads and picnic tables at the sites. They have very clean bathrooms and showers (one shower stall per bathroom).
It’s a very quiet RV park located about 8 miles off US 97 and north of Redmond, Oregon. Friendly owners are on site. There are seasonal RV’ers that I met who come and stay 3-4 months from hot places like Arizona. The owner said they do offer a monthly rate.
River Rim is a clean RV park and I would return if ever the area.
