There's one perk after summer has ended: Denver Zoo gives us free days. There are only two free days left for 2019, both in November. 

Typically, a day at the zoo can get pricey, especially if you have a lot of little ones. If you want to take advantage of the admission-free days, one is coming up on Monday, November 4 and again on Friday, November 8, 2019.
