Created by glaciers thousands of years ago, the preserve's towering 100-foot bluff once held famous CCC wooden toboggan runs. Today, it serves as a sprawling, fast-paced sled hill equipped with powerful floodlights for evening sledding under the stars. Next to the sled slope, the historic 125 limestone steps built in 1930 provide a legendary winter workout for active parents and teens. Sledding is completely free (bring your own plastic sled or saucer; metal runners and tubes are prohibited). The stone pavilion shelter at the base offers heated restrooms and a cozy place to catch your breath after conquering the bluff. ## Similar picks in Chicago - [Caldwell Woods Lit Sled Hill & North Branch Winter Trail](https://grassyknees.com/chicago/activities/caldwell-woods-lit-sled-hill-and-north-branch-winter-trail--listing-da7188813f01343b886e111b) — Dec 1 – Mar 1 · 10:00 AM – 8:30 PM · Caldwell Woods (Cook County Forest Preserves) · All ages · Free · checked Nov 4.
