The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.

Field Trips

A field trip day is typically four hours, unless other arrangements have been made. The duration consists of the length of one to two programs, site introduction, lunch, bathroom time and program wrap-up. Use of Forest Preserve District picnic facilities is included as part of your program permit.

Field trip programs are free for Will County schools. A fee of $2 per student applies to out-of-county schools. Payment is due 10 working days from the issuance of the program permit packet unless other arrangements are made.

In-person field trips are limited to 25 people or less.


Chaperones play an active role in programs. A ratio of one chaperone to 10 students applies for field trip programs. Chaperones are free of charge.

Programs take place outside, rain or shine. Field trips require walking on uneven terrain such as gravel, unpaved trails, and grass.
