Fall Foliage Walking Tour

Enjoy a walk through woodlands with an Arboretum ecologist.

Content Detail

Hike with an ecologist and take in the changing colors of The Morton Arboretum’s trees. This seasonal stroll will give you the chance to view fall color and learn what seasonal changes trees go through each year. You’ll get a chance to hear about:

  • why leaves change color and drop.
  • what discoveries scientists are making about these changes.
  • why some seasons have great fall color and others don’t.
  • what the timing of fall color can tell us about the bigger picture of our climate and local environment.

This program meets in person at the Arboretum.
