Sorry never been
Pets are not allowed on any park trails. Pets are only allowed in drive-in campgrounds, along park roads open to motor vehicles, and in picnic areas. Pets must be on a leash no longer than six feet and under physical restraint or caged. They may not be left unattended for any length of time. Kennels are available in several towns surrounding the park.
