Log the miles over days, weekends, weeks, or one big adventure. You have the entire month of October to do it!

  • Enjoy vibrant fall colors.
  • Spend family time on the Trail.
  • Slow down, unplug, and tune in.
  • Listen more and talk less.
  • Stop at every bench to rest and reflect.
  • Laugh, sing, and seek joy.
  • Watch a sunrise or sunset while on the Trail.
  • Take a night hike.
  • Introduce someone new to the Trail.
