Old School Forest Preserve

About Old School Forest Preserve

Large oaks dominate these woodlands that blend with small prairies. This landscape resembles what Lake County looked like when it was first settled. Bluebirds, foxes and screech owls are just a few of the animals living here. Time one of your visits to coincide with the August peak of prairie flowers blooming. You’ll be treated to a rainbow of colors, ranging from golden alexanders to purple milkweed.

Get outside and give back.
