About Union Flat Campground

Overview

Union Flat Campground is located on the North Yuba River, near Highway 49. Visitors enjoy a wide variety of recreational activities in the area, including hiking, hunting, fishing, canoeing and gold panning.

Recreation

The North Yuba River offers swimming, wading and rainbow trout fishing. Seasonal rafting, tubing and kayaking is available.

Facilities

The campground offers several single-family campsites and one double site. Some sites are designated for tent camping only. Each site is equipped with a picnic table and campfire ring. Vault toilets are provided.

Natural Features

The campground stretches along the north bank of the North Yuba River. A tumbled rock wall from early gold dredging activity separates campsites from the river. A forest of pine, fir, maple and oak trees covers the area, offering shade in many sites.

Nearby Attractions

Union Flat Campground is located on the Yuba Donner Scenic Byway (Highway 49) near many gold rush era historical sites and old mining towns such as Goodyears Bar, Sierra City, and Downieville. Many points of interest lie along Highway 49 and are part of the 49 miles of Highway 49 driving tour; look for interpretive signs and other historical sites along this tour route. Gold Lakes Basin offers boating, fishing, biking, and hiking. Boating, fishing and swimming are available at nearby Sardine Lakes, about 14 miles east of the campground. Sardine Lakes Resort offers boat rentals, lodging, and a restaurant. On the water, visitors enjoy boating and fishing. Anglers will find rainbow and brook trout in many of the lakes, streams, and rivers throughout the basin. Over 30 miles of maintained trails for hiking, mountain biking, and motorcycle singletrack branch out across the area and the Pacific Crest Trail can be accessed at a few spots east of Sierra City and in the Gold Lakes Basin area. The historic towns of Sierra City and Downieville offer historic and cultural attractions, restaurants, shops, churches, and vistor information.

Charges & Cancellations

No Show Policy

A no-show customer is one who does not arrive at a campground and does not cancel the reservation by check-out time on the day after the scheduled arrival date (or for day-use facilities, by check-in time the day of arrival).

* No-show customers are only recorded at staffed facilities. 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.

There is no change fee if a customer extends or shortens a reservation if the change includes dates from the original reservation. If they choose to depart early, they may forfeit some or all of the recreation fees.

There is no change fee if the customer changes campsites that are the same price and on the same reservation dates in the same campground. If the campsite the customer is changing to has a price difference, the customer will be responsible for any additional fees or be provided with a refund, based on the price difference.

Where recorded, no-show customers are assessed a $20.00 no-show fee and forfeit the first night's recreation fee for a campsite or forfeit the entire day-use recreation fee for a day-use facility. We recommend customers contact the facility if they are en route to their reservation but cannot make it by the check-in date. In these cases, no refund will be issued, but the facility can ensure that a "no-show" fee is not assessed.

In the case of motorcycles, the first two are considered to be one vehicle and the third and fourth are also considered to be one vehicle. No additional vehicle fees are collected for bicycles.
