According to the GTNP website, Signal Mountain is home to both black and grizzly bears and both animals are often seen in the area. Park officials remind visitors to practice bear awareness in the park at all times with the following advice:

  • Be alert and aware of your surroundings.
  • Make noise, especially in areas with limited visibility or when sound is muffled (e.g., near streams or when it is windy).
  • Carry bear spray, know how to use it, and keep it readily accessible.
  • Hike in groups of three or more people.
  • Do not run. Back away slowly if you encounter a bear.
