What Guests Are Saying
Union Flat offers a beautiful, quiet campsite with lovely tree coverage and proximity to the Yuba River, ideal for relaxation. However, some sites can feel crowded due to nearby mining groups and noise from Hwy 49 and mountain bikers. Notably, there is currently no potable water on-site, which can be a significant drawback for campers.

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.

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.
