Nestled at the base of the Sierra foothills where Dry Creek meets the Yuba River, Hammon Grove Park offers a glimpse into the rich past of Yuba County’s gold mining legacy.  Encompassing just over 40 acres, Hammon Grove sits where Long Bar - a town long since buried under layers of hydraulic mining debris - once flourished.  The land, a remnant of Wendell P. Hammon’s vast dredging operation, is littered with tell-tale signs of the quartz mining operation of days past.  From extensive water canals that traverse the property leading to the mine tailings brought forth from deep underground, the stories can all but be heard from the subtle evidence that the Yuba River once thrived with prospectors.


A one-mile trail that follows the circumference of the park affords visitors the opportunity to experience the essence of the Yuba County foothills and its natural splendor.  With majestic oak trees, California sycamores and towering pines, benches and tables along the way allow visitors to stop and enjoy the surrounding beauty.  River access is provided at one-half mile from the trailhead and a paved road also allows vehicle access from Highway 20 to the river.  Reservations are available for group functions.
