Sibley Volcanic Regional Preserve

About the dog park

• Open daily, Nov–Feb 7 a.m.–6 p.m.; Mar–Oct 7 a.m.–10 p.m.
• Run by the East Bay Regional Park District

Volcanic ridge preserve off Skyline Boulevard where dogs may be under voice control on trails, but must be leashed near entrances and wherever grazing cattle are present.

Rules

In many East Bay regional parks, dogs may be off leash on the trails if they stay near you, in sight and come back when called. Carry a leash no longer than six feet for each dog, and use it in parking lots, picnic and other developed areas, within 200 feet of trailheads and wherever a sign says so. Dogs must not chase wildlife or livestock or jump on people and other dogs. Pick up after your dog and put the bag in a bin. (East Bay Regional Park District)

Rules and hours can change, and dog parks sometimes close for repairs. Check the signs at the gate.
