Are there aggressive wild boars roaming in Horton Plains?

Yes, wild boars do roam in Horton Plains National Park, but they are generally not overly hostile to tourists unless they are trapped, cornered, provoked, or guarding their young.

These animals usually avoid people, and they prefer to feed deep inside the thick undergrowth of the park. If you hike the World’s End trail in Horton Plains, then remaining on the marked routes and keeping a respectful distance if you see a boar is entirely enough to avoid any unsafe situations.
