Fishing at Thatcher Pond
This 1.5-acre pond, next to the Trailside Museum of Natural History parking lot, is an old oxbow of the Des Plaines River and is prone to flooding. Its fish population is heavily influenced by the river.
Field Trips & Hybrid Learning
Our hybrid learning and field trip offerings allow teachers, parents and youth leaders to use forest preserves and nature centers as an outdoor (or virtual) classroom. Our hybrid learning programs serve kindergarten through 12th grade students and meet Next Generation Science Standards (NGSS), while our field trips serve everyone from pre-K to adult learners.
Contact one of our nature centers or firstname.lastname@example.org for more information or to discuss programs tailored to your learning objectives.
Established in 1932, Trailside Museum served as the first public nature education facility for the Forest Preserves.
Trailside Museum of Natural History is set within a historic 1876 mansion. The building has served many purposes through the years including being a residence and even housing two schools. In 1919, the Forest Preserves purchased the building, having already bought much of the surrounding land. The mansion served as the Forest Preserves’ headquarters until 1932, when the Board of Commissioners voted to make it a “trail side” museum displaying “every plant and animal in Cook County, live or mounted, for the education of the public.”
