Dog Policy

  • Grand Ravines South is home to the county's first enclosed off-leash dog park. Please review the dog park rules before visiting the park.
  • Dogs are required to be leashed (10’ max) and under control at all times.
  • Dogs are not permitted in park buildings, restrooms, picnic shelters, playground areas, off-trail, or as posted.
  • 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.
  • For more park properties that allow dogs off leash year-round, take a look at the Ottawa County Open Space Lands.

Grand Ravines Dog Park

Premiere off-leash dog park 
Includes 21-acres of enclosed dog park, with separated fenced areas for large and small dogs. Additionally, there will be fenced trails for off-leash walking. 
The Parks & Recreation Commission has already built the parking lot and support facilities and has allocated $75,000 toward building the park, but that will only pay for fencing and trails. In order to include the amenities that will make it a gold star facility, we will be seeking funding from local businesses and residents.

Additional funding is for:

  • Water service and doggy fountains
  • Lighting
  • Waste stations
  • Additional paved paths and benches
  • Modern restrooms
  • Picnic tables and a shelter area
