Free Day at Denver Zoo

While the free days at the zoo are always in the colder months, there’s still lots to see and the Tropical Discovery building provides an indoor escape to an Amazon Rainforest! Bundle up and come on down for free admission thanks to the SCFD and the citizens of Adams, Arapahoe, Boulder, Broomfield, Denver, Douglas and Jefferson counties who make these free days possible! TIP: Note the Zoo’s *Winter* hours of 10-4 daily.
