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 facilities were very well maintained and the camp hits were friendly and helpful!

@JimD11B8E413C5 · Camped on Jul 13, 2023 at Campsite #B11

The camp hosts are great! Great location to Yellowstone, clean and nice campground and some of the cleanest vault toilets I’ve seen.

@ScottD5141264 · Camped on Jul 11, 2023 at Campsite #B15

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!

@CharlesC950415 · Camped on Jun 20, 2023 at Campsite #B17

Vaulted toilets were exceptionally clean. Hosts were very kind and took care of the sites very well. Extremely happy to have them there.

@JoyceM4679249 · Camped on Jun 5, 2023 at Campsite #B13

Great spot! Wonderful hosts! Hit some good weather too.

@JosephF1050353 · Camped on May 29, 2023 at Campsite #B5

From the ease of check in, getting into the site and concrete pads, this has been one of the best RV sites we found on our journey. Having a BIG RIG (43' and tow) it was a pleasant trip.

@RobertB6182770 · Camped on Sep 11, 2022 at Campsite #B8

Very quiet and clean campground. Very friendly and knowledgeable campground host.

@ThedaT8389096 · Camped on Aug 31, 2022 at Campsite #B15

We wanted to paddle the river with our canoes. The camp spots are very clean and accommodated our camper and canoe trailer perfectly. Wonderful experience.

@KevinP4445220 · Camped on Aug 21, 2022 at Campsite #B10

@JulieI6988438 · Camped on Aug 20, 2022 at Campsite #B16

A-mazing place. I was told by a family member that the bathrooms are very clean. The camp hots were very attentive. We are looking forward to returning!

@DustinR9123808 · Camped on Jul 27, 2022 at Campsite #B10

Dan and Annie were by far the best camp host we have experienced. This was our first time going to the Yellowstone area and they made the campground top notch. Lots of help and we would visit again any time.

@AllisonH674550 · Camped on Jul 25, 2022 at Campsite #B17

Thanks to all our Supporting Members

@BranJen - Santa Clara, CA

I wanted to thank you for this site and especially for the notifications feature. Thanks to your site and my subscription I was able to book a campsite I've been annoyingly trying to book for 5 years unsuccessfully. So thank you.

@Wondering - Oregon

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.

@CarlaLThompson - Colorado

I just love this site and I tell everyone about it! It's so competitive to secure desired campsites and the alerts really help track when sites free up. The best part of this story is our alert notified a cancellation the next day!!!!!! Just incredible!!!
