Group Volunteers

The Houston Zoo welcomes corporate, school, and other community groups to fulfill large project needs and connect with our mission. 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.

Project Categories

  • Outdoors Labor Projects – Raking leaves, moving substrate (soil, sand, rocks, gravel), weeding, planting shrubs, etc. Most projects are outdoors and are only available on Sunday through Thursday mornings, based on project need.
  • Outdoors Special Events – Helping with event setup, greeting guests, facilitating craft and activity tables, 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).
  • No matter the project, your group may be split into smaller teams to accomplish tasks.
  • Most projects involve physical labor


Group volunteers are typically scheduled for projects lasting up to three hours. Zoo projects can accommodate a group size of 10-25, depending on the area. Please note that project availability is limited and must be pre-scheduled; 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.

All group volunteers granted a project will be scanned through Raptor background check screening.

Come make a difference while learning about conservation and having fun! Volunteers must bring their own reusable water bottle to help save wildlife.


We will not have projects available through 2020. Please check back for 2021 availability. All updates will be posted here as soon as they become available.

Reusable water bottles save you and save wildlife

Using a reusable water bottle means you stay hydrated and you save animals like sea turtles from plastic pollution caused by single-use plastic bottles.

Bring your reusable bottle and fill it up for free throughout your visit.

Since 2018, our group volunteers have helped keep 551 water bottles out of landfills!
