#1 Give wildlife a brake. Unless posted slower, the park speed limit is 45 mph (73 kph). You may encounter animals unexpectedly, please slow down to assure yourself enough stopping distance.
#3 Campfires are allowed only in designated grills in park campgrounds, some picnic areas and specific backcountry campsites. Ask locally about current fire restrictions.
#4 Do not approach wildlife. You must stay at least 100 yards (91 m) from bears and wolves. A distance of 25 yards (23 m) is required from bison, elk, and other animals. Regardless of distance, if any animal changes its behavior due to your presence, you are too close.
#5 Do not feed any wild animals, including birds, squirrels, and coyotes. Consuming human food is unhealthy and encourages aggressive behavior that may require the death of the animal. All food, trash, coolers, and cooking tools must be kept secure in a bear-proof container or vehicle unless in immediate use.
#6 Stay on designated trails and boardwalks. Ground in hydrothermal areas is fragile and thin, and there is scalding water just below. Visitors have fallen through and died here. Keep yourchildren close at hand.
#7 Avoid water hazards. Park waters can be deceptively cold and swift. Do not take risks while fishing, wading, or crossing streams. Swimming is unsafe and prohibited in many areas. All boats and float tubes require permits.
#9 Control your pet. Pets are not allowed ontrails or boardwalks, in the backcountry or hydrothermal basins. Where allowed, pets must be leashed and remain within 100 feet (30.5 m) of a road or parking area. Do not leave a pet unattended or tied to an object. Owners must bag and dispose of pet waste.
