Tune in - Help us safeguard the sounds of life
There is a whole new world of sound waiting to be revealed. Here are some tips to help you become attentive listeners in national parks.

  • Take a moment to close your eyes and listen to the sounds around you. You may be surprised by what you hear.
  • Speak quietly and turn off vehicle engines whenever possible.
  • Look for mute options on electronic equipment such as cell phones, watches, or cameras.
  • Follow park rules on motorized recreation, and be courteous and respectful on your motorcycle or boat.
  • Turn off car alarms. Disable sound on electronic door locks.
  • Use alternative transportation such as shuttles when available.
  • Be aware of campground quiet hours.
  • Be respectful of others. The sounds you make will affect the experience of other visitors. Encourage friends and family to do the same.
