What Guests Are Saying
Union Flat offers a beautiful location near the Yuba River, with clean bathrooms, tree coverage, and a peaceful atmosphere for camping. However, the campground lacks potable water, has significant noise from nearby Highway 49, and experiences issues with late-night disturbances from other campers. While some sites felt small and crowded, many guests appreciated the scenic surroundings and the soothing sound of the river.

There was no water in the campsite at all. The water spigot that used to be there looks to be out of order indefinitely.
Plenty of water down the road at Loganville.

We tried this site because the other sites had no spaces. It was next to the highway and very loud with traffic driving by, and of course once again all the mountain bikers stayed up very late making lots of noise. I thought this time would be different but it was NOT!!

This site is next to Hwy 49, noise from cars and a lot of mountain bikers stating up late making noise. The other campgrounds are much better and not on the main road.

Sites were too close together, and sites were small. We selected site 10 online. When we arrived it was in a dead-end culdasac formation all the other sites were occupied with multiple cars/trucks. We did not what to feel that close or crowded so we decided not to stay.

Pros- Beautiful area, spaced reasonably apart, up against Yuba river , nice tree coverage, clean bathrooms.
Cons- Very close to the highway with occasional race cars and pocket rockets. Water for campers was shut off. Non- poisonous snakes in the river. Though my wife got a cool video of one eating a trout.

Loved being right next to the river. Site 6 was a little small for 2 tents but we made it work. Mosquitos were very bad for June and no running water made the trip not fun but overall loved it!

its nice but don't trust the first come first serve rule. there is no camp host so bring your own toilet paper and the reserve signs are lacking. with no cell phone reception or no number to call its hard to contact anyone with any problems.

I was extremely disappointed that my reserved site was not reserved. The river/creek was not as close as the photos made it appear.

The toilets were very well cleaned on a regular basis, a lot better than previous years. The cleaners do a great job.
Water supply not working, would have been good to know this before we got there.
