Calving Season Advisory: Admire from a Distance

Calving season runs August to October in

Regional Parks. Be mindful of interactions that can create a danger to both calves and people. Calving season tips for visitors:

• Do not approach or touch baby calves. Do not take selfies with calves.

• Do not get between a mother cow and its calf.

• Do not worry if you see a calf by itself. The mother cow is usually nearby and will return.

• Leash your dog around cattle and keep them away from calves.

If you see a calf that is distressed, injured, or sick, please report it to park staff at (510) 881-1833. More info.
