Roberts Regional Recreation Area (RRRA) is an area adjacent to Redwood Regional Park located in Alameda County next to Oakland, CA and is part of the East Bay Regional Parks (EBRPD). It is across Skyline Drive from the City of Oakland's Joaquin Miller Park. Kaiser Aluminum and Chemical Corp. adopted Roberts Park in 1979, under the newly-developed Adopt-a-Park program, which promised continued funding. This was the first park in EBRPD to be so adopted.
Roberts Regional Recreational Area has picnic tables, playground and a seasonal pool with lifeguard.

## History

California Historical Landmark #962, "Blossom Rock Navigation Trees," is located in the Madrone Picnic Area of the Roberts area. It describes how two of the most prominent redwood trees were used by sailors entering San Francisco Bay during the early 19th Century to avoid hitting a submerged hazard known as Blossom Rock. The rock was between Alcatraz Island, Yerba Buena Island and the Port of San Francisco.
The rock was first reported in 1827 by a British sea captain. It was finally rendered non-hazardous in 1870 by the Corps of Engineers, using a combination of drilling and blasting. Meanwhile, the "Navigation Trees" were cut down between 1851 and 1855, leaving ships entering and leaving the Golden Gate for nearly two more decades.
The RRRA area was covered by redwood trees that were logged between 1840 and 1860 to provide building materials needed to support the explosive population growth in San Francisco and Oakland immediately following the discovery of gold in California. Redwood trees presently in Roberts and Redwood parks are second growth.
Roberts Regional Recreational Area opened to the public in 1952. It was named for Thomas J. "Tommy" Roberts, then secretary to the East Bay Regional Park District board of directors for 24 years. He continued to serve on the board until his death in 1958, at age 95.

## Activities
