All regional parks in the East Bay will be open this Memorial Day for annual holiday gatherings and celebratory festivities. Parks are anticipated to be busy and some at full capacity early, so park staff recommend arriving early to secure first-come, first-served, non-reservable picnic sites.
Many lifeguarded swim areas will also be open for visitors, including Castle Rock Pool at Diablo Foothills in Walnut Creek, Cull Canyon in Castro Valley, Don Castro in Hayward, and Lake Temescal in Oakland. Non-life-guarded beaches include Keller Beach at Miller Knox Regional Park in Richmond and Robert Crown Memorial State Beach in Alameda. Unfortunately, many of the Park District’s most popular swim areas, including Del Valle, Shadow Cliffs, and Lake Anza will be closed due to water quality, low water conditions, or construction and maintenance repairs.
“We regret the inconvenience and limitations on the public’s use of all of our swim facilities,” said Dave Mason, Public Information Supervisor.
Park District swim facilities face ongoing challenges related to climate change, including cyanobacteria (blue-green algae) and low water levels. Water quality is tested regularly during the swim season to ensure it is safe for the public. Visitors should check the status of swim facilities before they go by visiting www.ebparks.org/swimming.
