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.

I tired this site again and it was very loud with traffic noise and people parting into late night

Had the entire fam, and it was a small site, with lot's of highway 49 traffic very close. No water or cell service, the campground up the street was much better and no hwy noise

No water spigot here. Plenty of water down the road at Loganville Campground.

Nice spot next to the river which drowns out car noise on hwy 49. Trash and recycling dumpsters near the entrance. Quiet. No potable water. No electricity in pit toilet bathroom. No problem for us!

Even on Memorial Day weekend this place was nice and quiet. Sites are decently spaced so you don’t have to hang out with your neighbors. Having the sound of the river meant we slept like logs.

Stayed at site 11. Barely a walk to. Campfire is 100 ft from parking area. Didn’t run into any noisy mountain bikers and the sound of the river silenced the few passing vehicles.
Absolutely loved this spot. Shouldn’t be rated so low.

The location is always beautiful and the rock we hang out every day for hours. The river was awesome this year.

The sites at the far end of the campground, I think 9 and 11, share the space with a separate group of people that are part of a gold mining group or something. They are not part of the reservations system and have their own claim to that area.
It makes that part of the campground pretty crowded with these extra cars, trucks, trailers, campers, people and dogs.

No cell service, and lots of noise from hwy 49.
