Dogs on leash are permitted at Grand River Ravines North year round, but on trails only from May 1 through September 30. For the safety and enjoyment of all park guests, pets must be on ten foot leashes and under control. Dogs are permitted year round, off leash at Grand River Ravines South. Owners must clean up after their pet and dispose of waste in a trash receptacle. Leader dogs for persons with disabilities are permitted at any time. Recognizing that most dogs enjoy running and playing freely, Ottawa County Open Space Lands allow dogs year-round off leash.
