This is a large Forest Service campground stretching along the shores of Diamond Lake. It is difficult to do a full review of this campground as we were there at the end of the season when it was cold, windy, and rainy. There was no staff on-site, and it was only the next morning that I saw an occupied host site way at the other end of the southern part of the campground. The north end of the campground had already closed for the season, and I believe the south end closes at the end of October. Reservations are only available June through Labor Day, but we pretty much had our pick of sites on a weekday in mid-October. 

The road and camper pads are paved, and a good amount of foliage between sites provides privacy. 

As far as activities, there is a paved bike path that winds through the campground. In season, there is boating (there is a boat ramp in each end of the campground), and there is a fishing dock too. 

In each end of the campground, there is one “nice” bathhouse that is clean, heated, well-lit, and has showers. Depending on where your site is, it may be quite a walk to get to these bathrooms. Note that showers are free but there is a donation box. I wouldn't be surprised that at some point in the future, they will require payment. Sprinkled throughout the rest of the campground are very basic bathrooms with one sink, two stalls, cold water only, no soap. It had last been cleaned three days before we were there and there was no toilet paper in the men’s bathroom closest to our site.

There is also a dump station with a donation box.

Rates are reasonable, especially if you have the senior Golden Access Pass, however, there was a note that each transaction also incurred a $3 transaction fee. Didn’t know if that was if you reserved online, used a credit card, or no matter. We included it in the envelope for a total of $14.
