To protect wildlife, the experience of other visitors, and your pet, the following rules apply at Zion National Park:
Leashed pets may be walked on the Pa'rus Trail. All other trails, and all wilderness areas, are closed to pets.
Pets are not allowed on shuttle buses or in public buildings within Zion.
Pet waste must be immediately removed and disposed of in trash receptacles.
Pets must be under physical control on a leash less than six feet long at all times. Properly restrained pets are allowed along public roads and parking areas, in the developed campgrounds and picnic areas, and on the grounds of the Zion Lodge.
Zion is hot! The interior temperature of a vehicle can quickly warm to dangerous levels, during most months of the year. Leaving a pet unattended in a vehicle with environmental conditions that pose a health risk to the animal is prohibited.
