Regular adult admission at Denver Zoo is $27, so timing the visit to the free window keeps $54 in a couple's pocket and up to $108 for a family of four — each published date. And since this free day is open to everyone, it's the cheapest possible way through the door. The catch is capacity, not money: free slots are reserved in advance and the popular dates go first, so the reservation is the real currency here.
Regular tickets ($27 adult (ages 16-64)) are on denverzoo.org; buying direct means no reseller markup. Already a member somewhere else? Our reciprocity lookup checks whether that card covers admission here.
