Fantastic, well maintained, and well equipped camp ground. The Prineville Reservoir camp sites were clean, had a variety of hookups depending on what site type you book, and had very clean bathrooms and showers available. Not a fisher myself, but heard multiple good reports from the numerous people on the water who were fishing.
The reservoir doesn't feel man-made at all, and it stretches for miles. Lots of wake boarding and kayaking. Water felt nice to swim in as well.
To my delight, we discovered that this camp ground is a recognized International Dark Sky spot, meaning the especially dark sky is perfect for star gazing. They even have an observation spot with telescopes that they will occasionally open to the public on weekend evenings. Very relaxing area, will be coming back again! Reasonably priced as well.
