This is a good thing to keep in mind over the holiday break. 

The Brookfield Zoo is pretty cool. Getting to do it for free is even cooler.

If you've never made a winter trip to the zoo you have missed out. While some of the animals have moved inside for the year the ones that are outside are usually a lot more active than they are in the summer. Between the cooler weather and the lighter crowds, the animals seem to really start to let loose.

That's why you should take advantage of Brookfield Zoo's free days that are available for the rest of the year.

Every Tuesday and Thursday Brookfield Zoo offers free admission to all guests.
