General Volunteer Info

Thank you for your interest in volunteering at the Houston Zoo! Volunteers support every department of the zoo including animal care, education, and guest services. Volunteering at the zoo is a serious commitment; adult volunteers serve for at least a year – some volunteers have been with us for a decade or more! Group volunteers donate their time for special projects on a one-time basis.

There are two types of volunteer opportunities:  Adult Volunteers and Group Volunteers

Adult Volunteers

Join the team of over 400 adult volunteers (18 and older) who contribute their time to help make the Zoo a great place to visit and to save animals in the wild! Our adult volunteers are provided training and support, invitation to special volunteer appreciation events, discounts on concessions and Zoo membership, and the opportunity to develop new skills and make new friends!

Some of the opportunities for adults to volunteer include:

Animal Encounters – helping staff supervise guest interactions at Giraffe Feeding and Children’s Zoo

Interpretation – educating guests about the individual animals here at the zoo and what we are doing to save them in the wild

Education Program Assistant – helping staff to help teach classes and lead activities

Guest Services – greeting guests, answering questions, and helping to ensure their day is amazing

Keeper Aide – volunteer alongside our keeper staff and assist with habitat cleaning, enrichment, diet preparation, and more!

Zoo Events – assisting staff with various conservation and community events throughout the year

Animal Handler – help our guests get up close and personal with one of our ambassador animals

How to apply:

We accept applications during our three recruitment periods – March, July, and December

Approved applicants are contacted for a meet & greet with zoo staff and current volunteers at the end of the application period; a full day orientation is required if accepted

Once a volunteer is accepted there is a $55 charge for background check, uniform, and name tag. If you have lived internationally, there may be additional charges associated with your background check. 


60 hour yearly commitment (an average of 5 hours per month)

Ability to communicate in English (additional language fluency is a plus!)

A negative TB test result is required for all incoming volunteers

You must be able to attend one of the following orientation dates: February 3 or 11, 2018.

We are accepting Adult Volunteer applications for those primarily interested in Education, Events, and Guest Service, now through December 31st! 

Group Volunteers

The Houston Zoo welcomes corporate, school and other volunteer groups to help fulfill the Zoo’s project needs. All group volunteers must be age 13 or older and at least one adult chaperone for every 10 volunteers under the age of 18 is required.


Group volunteers are typically scheduled for projects/shifts lasting up to four hours. Most Zoo projects can accommodate a group size of 25 or fewer. Please note that project availability is limited and requests should be received at least 30 days in advance. The exact project will vary due to the time of year and needs of the Zoo.

Most projects will be outdoors and many individual project days will only be available on weekday mornings.

Project Categories

  • Outdoor Projects – Raking leaves, moving substrate (soil, sand, rocks, gravel), planting shrubs, flowers, etc. Projects may be available 7 days a week.
  • Special Events – Helping with event setup, greeting guests, manning craft and activity tables, providing event support, cleanup etc.; activities will involve interacting with our Zoo guests so be ready to engage in conversation! Projects will typically run on Fridays-Sundays during Zoo hours (example:  Zoo Boo).

We are now accepting applications for group volunteers!
