We stayed for 4 nights, initially planned 5 5 nights, we left a night early because of bad weather.
The camper cabin was fine but privacy was not really there due to the way the cabins are placed. And we missed the option of hooks and or shelves in the cabin. I guess the place is mostly set for people staying only one night not 4 or 5.
The bathrooms were clean when we came but became dirtier as the days past. The showers were nice and warm so that was very pleasant.

Great campsite!! It has free showers, convenience store and a gas station nearby. We stayed in a cabin with no electricity or water and it was still great. Very clean, well maintained.

We were able to get a tent and RV site side by side. And the last night we were able to get a site big enough for all of us. The campgrounds were clean, and we enjoyed camping in the forest. The staff were very pleasant and helpful. We would stay there again.

We really enjoyed our stay at Headwaters at Flagg Ranch. The RV spaces were large and easy to get into. We loved the proximity to the creek/river and the gas station (with diesel as well), lodge with restaurant and available propane so close to the campsite. The location was also just a quick jaunt to the lake.

Campsites are very close together, so if your neighbor has a smoky fire, you have a smoky camp.
Liked the outdoor washing station. Liked that the staff were vigilant in checking to make sure people were not leaving items out that bears would find appealing.

Classic, very large commercial CG, we were in our pop-top van so stuck to the western edge as to not be shoehorned btw some giant rigs. Fine for a night, but I would not look forward to staying here in a smaller rig or tent. UPSIDE is very nice showers.

Bathrooms were a little grungy and the "kitchen sink" outside to wash dishes was clogged and full of nasty water.
