Fodor's Parks 101: Pets in the Parks

Generally, pets are allowed only in developed areas of the national parks, including drive-in campgrounds and picnic areas. They must be kept on a leash at all times. With the exception of guide dogs, pets are not allowed inside buildings, on most trails, on beaches, or in the backcountry. They also may be prohibited in areas controlled by concessionaires, such as restaurants. Some national parks have kennels; call ahead to learn the details and to see if there’s availability. Some of the national forests (www.fs.fed.us) surrounding the parks have camping and are more lenient with pets, although you should not plan to leave your pet unattended at the campsite.
