Steps to Become a Volunteer

Volunteers play a vital role in supporting Denver Zoo’s mission by enhancing the guests’ experience by connecting them with animals and their environment through their passion, commitment, dedication and knowledge.

We are currently not accepting applications for the remainder of 2021. Please check back for recruitment updates in 2022.



If you are accepted into the program, you will receive an acceptance letter requesting you to accept your volunteer position and team assignment.


All adult volunteers are required to complete and pass a criminal background check. There is a $35 training fee that is required of all volunteers. Scholarship support is available on request.


All adult volunteers must attend a full, one-day orientation called Zoo U. This orientation will give you an introduction to Denver Zoo, our mission, Adult Volunteer Program staff, and the skills necessary to provide the highest standard of guest experience.

*Note: Additional job-specific training is required depending on your interests before you can start volunteering.
