Pets on a leash no longer than 6 feet are allowed in some areas of Grand Teton National Park, located in northwestern Wyoming. Pets are allowed on roads and road shoulders, campgrounds and picnic areas, parking lots, and basically, anywhere a car may go. Pets are not permitted on any park trails, in the backcountry, on the park’s multi-use pathway; in boats on park waters, except for Jackson Lake; and from public buildings and swimming beaches.
