Bison can be viewed from outside the bison fenced units only. The bison roam across 1,500 acres of rolling land and are often not visible from the road. Binoculars are helpful. No hiking is permitted inside the fenced North or South Bison Units. When viewing the herd, visitors should pull off the road, turn on their hazard flashers, and park where they do not limit access to private driveways or Nachusa fence gates. Folks can park at the Visitor Kiosk on Lowden Road and walk up the hill to the Autumn on the Prairie site for a possible view of the bison. Keep in mind that they can now roam over 1,500 acres, so they will often not be visible from roadsides or fence perimeter.
