All regional parks in the East Bay will be open Memorial Day 2025 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-serve non reservable picnic sites.

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.
