We stayed here mid June 2018, it was very quiet. We arrived late at night and were able to find a site to stay in with little difficulty. The mosquito population, however, was quite thick at that time if year so cooking during the daytime wasn't as fun as we would have liked. Overall it was pretty and clean. We would stay here again, but possibly in the mosquito off season.
Typical drive through RV campground. Sites located between main highway and lake edge. There is some distance between sites and each has a pretty good view of the water. Hiking / biking path around lake gives you access to a pizza parlor and Diamond Lake lodge with swimming and boat rentals. Great for bike riding.
