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.

No potable water available on site. Recreation.gov site lists drinking water as available, but none on site on arrival

A total let down! Got stuck at this campsite because the nice campground Loganville up the street was full. This site is located 25 ft from Highway 49 so plenty of traffic noise. It's small and only one dirt road (no loop) so everyone that drives in looking for a spot turns around and drives by again dusting out every set-up campsite, Total dust fest! Plenty of partying going on in many of the sites if that's what your into. We actually had someone in the middle of the night mistake our tent for there's and began to enter our tent until I yelled. I'd stayed here again if they gave me a $1000 dollars.

Very few places to find a level spot for a tent. Very few spots for a tent that aren't completely rocky. This campground is located on a site where tons of rocks from the river bed have been displaced (on to the current campground area) for industrial gold mining purposes. It's also just a few yards away from the highway traffic.

Clean campgrounds, the bathrooms were well stocked with TP and kept clean. The sound of the rushing water in the river was very lulling. In a great location to explore Downieville, Sierra City and the Lakes Basin.

Lots of loud bikers partying all night. It's great if you like campers next to you playing music till 3am.

Clean, convenient facilities, and very nice to be able to dip our feet in the river after a long day of riding.

Such a beautiful, secluded campground on the river. Absolutely will be back.
