The Denver Zoo is open all year round but is slow during the winter months.  So, they decided to give their visitors a reason to come in the winter months with free admission on select days.

There is still time to take advantage of free admission during January, like Friday the 18th and Saturday the 19th are free admission to everyone.  Then in February, it is free on Sunday the 3rd and Monday the 4th.  Then after that, you will have to wait for all the way until November 4th and 8th for free admission again.

The zoo is normally $15 for adults ages 12-64, $13 for seniors, $10 for children between 3-11, and kids 2 and under are always free.

If you can't make it for one of the free days, go here to get your tickets now so you don't miss out.
