Your safety depends on your own good judgement, adequate preparation, and constant attention. Backcountry hikers should be in good physical condition and be able to survive on their own. Proper equipment and the knowledge of how to use it are essential for a safe trip. Your safety is your responsibility.
Some basics to help you get started:
The following factors often result in backcountry emergencies in the Smokies:
Significant hazards that you may have to contend with include stream and river crossings, precipitous cliffs and ledges, unstable sedimentary rock, dangerous wildlife, and ever-changing weather, including snowstorms and lightning.
Dangerous Stream Crossings
Heavy rains cause swollen streams that may be unsafe to ford. Use good judgement. Do not attempt to cross flooded streams. If your route is blocked by a rain-swollen stream, please backtrack and attempt to return to the nearest campsite or trailhead. Do not risk your life trying to follow a planned itinerary!
When crossing streams, wear shoes to protect your feet and a use stout stick for added support. Unbuckle the waist strap of your pack so it can be discarded quickly.
Read additional water safety information.
Treat All Drinking Water
The protozoan Giardia lamblia may be present in park waters. When ingested, their reproductive cysts may cause an intestinal disorder that appears weeks after your trip. The easiest method of effective water treatment is to boil water for one minute or use a filter capable of removing particles as small as 1 micron.
Hypothermia Kills—Even in Summer
Be prepared for sudden weather changes. Cool, wet, and windy conditions can cause hypothermia. Hypothermia is a progressive lowering of the body's core temperature causing physical collapse and diminished mental capacity. A wet hiker can succumb to hypothermia in summer at higher elevations! Prevent hypothermia by using rain gear before you become wet. Wear wicking clothing and leave cotton clothing at home. Cotton clothing will not dry out once it becomes wet.
Minimize wind exposure and if your clothes become wet, replace them with dry ones. Avoid sweating in cold weather by dressing in layers, rather than a single bulky garment. On warm days watch for signs of heat exhaustion.
Stay well-hydrated in all conditions-three to four quarts of water per day is required to avoid dehydration.
Encounters with Bears
Bears in the park are wild and their behavior is unpredictable. Although extremely rare, attacks on humans have occurred, inflicting serious injuries and death. Treat bear encounters with extreme caution!
Bear spray may be carried by hikers within Great Smoky Mountains National Park for the strict purpose of protection against bodily harm from aggressive wildlife. It should not be applied to people, tents, packs, other equipment or surrounding area as a repellent. Bear pepper spray is a chemical formula designed specifically to deter aggressive or attacking bears. It must be commercially manufactured and labeled as "Bear Pepper Spray" and be registered with the Environmental Protection Agency and individual states. Bear spray must contain between 1% to 2% of the active ingredients capsaicin and related capsaicinoids.
Two species of venomous snakes live in the Smokies, the northern copperhead and timber rattlesnake. Although very few snake bites occur here, visitors should be cautious where they place their hands and feet, especially around old buildings and stone fences. No fatalities from snakebites have ever been recorded in the park.
Yellowjacket wasps are the insects of greatest concern. They build nests in the ground along trails and streams and are aggressive when disturbed. Avoid perfume, powder, and scented deodorants which may attract yellowjackets. Stings cause local swelling and can lead to severe allergic reactions in a few sensitive individuals. Such persons should carry epinephrine kits.
Ice and Wet Leaves
In winter, most trails at high elevation will be covered with ice. Use crampons or other traction devices for your boots. In autumn, loose, slick leaves on the trail cause many hikers to fracture their ankles. Be certain to wear ankle supporting boots.
Trees and Limbs
Before you sit down for a rest or set up camp, take a moment to look up and around you for any trees or limbs that may pose a hazard. Move away from any areas that may be threatened by tree or limb fall.
