What Guests Are Saying
Union Flat offers a beautiful location near the Yuba River, with clean bathrooms and pleasant tree cover, making it a lovely spot for relaxation. However, some sites, especially near Highway 49, experience noise from traffic and late-night mountain bikers, leading to a crowded atmosphere. Additionally, the lack of potable water and limited cell service were notable downsides for visitors.

Stayed at site 11. Barely a walk to. Campfire is 100ft 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.

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.
