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.

This is a great place to camp by the river. The campground is well kept. The Camping sites are mostly small so for larger campers, RV's it would be a tight fit at most sights. There are A couple of Group sites here and they are large enough to accommodate a fairly large number. There are also a few 2-4 larger sites where you might fit an RV. There are no electrical hook ups here. Vault toilets are pretty well maintained. We had a great time here although pretty hot in August.

It was HORRIBLE!! Campground was full of rude, obnoxious, loud, offensive, and disgusting Clampers! They threatened us, because we didn't want them walking through our campsite, so we packed up and left after one night. They had the nuts to clap and cheer as we left with three rigs. I will never, ever go back to Union Flat. Period!!

Beautiful campsite right on the Yuba river outside of Downieville. Campsite if pretty close to the road, but all in all an amazing spot. Would be a great place to camp if you are mountain biking Downieville or wanting to fish the Yuba.

The campsite at Union Flat was clean and enjoyable. The Rangers were always friendly and helpful. I'm looking forward to returning when the weather warms.
