Muddy Trails

Shortcutting around muddy trails greatly increases erosion and destroys vegetation. If a trail is reported to be in poor condition, consider using another trail.

Tips for Muddy Trails

  • Use trails early in the morning before it gets too muddy
  • Go through mud, not around it – trails take years to heal, so get muddy
  • Use a different trail if it is too muddy
