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.

Great location, my second time staying here. Nothing like going to sleep with the sound of a river 30 feet away.

I always love camping at Union Flat. Ive been camping there for over 28 years. I am disappointed with your reservation system portal. First the map is wrong. The pictures associated with some sites are wrong. Also its disappointing that you dropped more Fcfs sites. (Down to 1) however even with the messed up online reservation system, its always good to stay at Union Flat.

At most remote facilities, all customers are noted as automatically checked-in on the date of arrival.* It is recommended that staffed facilities hold a campsite until check-out time on the day following the arrival date.* It is recommended that staffed facilities hold group day-use facilities until check-in time on the arrival date.
