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.
@ChristiL930288 · Camped on Jul 7, 2025 at Campsite #B13
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.

Excellent campground! The camp host Annie is wonderful! Bathrooms were the cleanest around. We will definitely be back!
@JamesM9879118 · Camped on Jun 20, 2025 at Campsite #B7
The facilities were great and the campsite was clean. The one reason that I will never camp there anymore is your camp host was mean. Very rude. Every time I had an interaction with her and accusing when I had questions. I wasnt the only one that had this experience. Everyone that was in our camp party had the same exact experience with this woman. If camp host were changed, I would consider going back, but until that woman is removed I will not be going back to that campsite.

Good campground host.
@TraceyS6865254 · Camped on Jun 12, 2025 at Campsite #B13
We had a great time. The campground Hostess was ever-present (which is a good thing) and the campground was clean and beautiful. We saw lots of wildlife and enjoyed the serene beauty of the area. Thank you!

The campground host does a outstanding job of taking care of the campground as well as keeping track of the visitors. Clone her and put her is all the campgrounds

The site was clean, cared for and easy to get in and out of. The hosts were friendly and welcoming.
@JackA1060667 · Camped on Jun 1, 2024 at Campsite #B6
Good Campground. Only 3 sites were used and the whole rest of the campground was available. This was not normal.
@JohnB8383631 · Camped on Sep 1, 2023 at Campsite #B6
This campground is close enough to Yellowstone national park and the price is right.
@FrankH3694048 · Camped on Sep 1, 2023 at Campsite #B15
We love this campground. The host is friendly and keeps the bathrooms nice and clean. She comes around to check on us. Ready access to Mack's Inn and the Big Spring area. 45 min from West Yellowstone.
@MarionT75A139F · Camped on Aug 17, 2023 at Campsite #B6
Wonderful, clean campsites, and the host was wonderful! The host name was Annie. I would definitely stay here again, and tell my friends about it.
@JohnT2915386 · Camped on Aug 7, 2023 at Campsite #B6
Flat Rock campground is a very clean campground. The campground hosts are very nice and fun to talk with. The sites are are spacious with great fire pit and large tent pad. There was a place to park our 4-wheelers. Close to 4-wheeler trails and all the beauty of the area.
@DerekS4544392 · Camped on Jul 22, 2023 at Campsite #B6

The campground was nice. It’s close to mesa falls which is pretty to see.
@HeatherL387189 · Camped on Jul 1, 2023 at Campsite #B7
This was a great campground. Beautiful, clean, spacious, the works. The only drawback was the road noise. Otherwise, amazing experience!

I just used PerfectCamp.com to book six consecutive August nights at the most popular campsite in one of the most popular campgrounds in Humboldt Redwoods State Park in California. That is not anything I could have accomplished anywhere else with the ease I did here! Thank you, PerfectCamp! I LOVE this site! You will find me on several other camping sites but the design, format, functionality, and personality of this the best. It’s fresh and clean.

Wow! Woke up this morning to a notification that a favorite had opened at Paulina, and when I went to check, it was there. This membership just paid for itself in the first 24 hours I owned it. Couldn't take the site it conflicted with a trip already set, but it truly was there. Thanks Tons.
