Flat Rock Campground in Idaho offers a clean and well-maintained environment with spacious campsites and beautiful surroundings, making it a great spot for families and outdoor enthusiasts. Many reviews highlight the helpfulness of camp host Annie, who is praised for her dedication to maintaining the campground. However, some guests report issues with noise from the nearby highway and mixed experiences with camp hosts, suggesting improvements in host interactions and garbage management would enhance the overall experience.

We love this campground and go there every year and sometimes twice. This year we are going again. I was very disappointed. The garbage was full and not cleared for the time we were there - Mon - Wed.
The campground hostess was not pleasant. In fact, I thought she was very rude to us a number of times. My husband approached her about paying for the extra car we had and before he could say anything she flew into him about not having extra vehicles, which we knew, and were happy to pay for. We had my mother [87 yrs] so took our truck to pull the camper and a car to travel around in to accommodate her. That was not a good start.
She brought us the info on bears and I explained that we were aware of the rules, as we had camped there every year. I said we would not leave anything in the tent or out from meals. Her comment - well you better not.
On leaving, I went to ask her about the garbage again so we could dump before we left and she said - can't you see - it is still locked. We had thought we had heard the dump being emptied and I mentioned that and she bit back at me again.
Before pulling off, I suggested she try being polite and pleasant to people using the park. As I pulled off, she shouted something else to me.
I was very disappointed - and then realized I had to go back in September!!!!
We have never had a rude camp host like this in any of the campgrounds. They are usually pleasant and helpful. I am sorry that I have to write this negative review - and as I said - I'm not looking forward to going back.

Our experience was made special through the suburb campground host, Annie. Her conscientiousness and care for people is exceptional.

Great location for shade and close to the river for cooling off in the summer. Lot's of activities all around. Close proximity to Yellowstone National Park was a key factor for our group. Go early in the morning for the busy season or you have to wait in line just to get into the park.
Camp has a fair amount of road noise due to close proximity of the highway, but very tolerable.
