Guest Experience Volunteer

Calling all nature nerds, animal advocates—and anyone who has always dreamed of helping people connect with the wonder of wildlife. Volunteers guide guests in this connection to animals and the mission of Denver Zoo. These positions include information carts, camp assistants, and conservation spotlights! Guest Experience volunteers also have the opportunity to pursue Docent training for exhibit interpretation roles. This is our highest need and largest volunteer team. 

Animal Care Volunteer

For the right person, a so-called "dirty job" can be a dream job! If you're looking for a Denver volunteer opportunity that involves wild animals, you may have found your people. Keeper Assistant positions include helping with routine work such as cleaning, dish washing, and diet preparation. Our Animal Behavior Observers watch individual or groups of animals and record specified behavior to help our Animal Care staff. 

Horticulture Volunteer

Do you like plants at least as much—if not more—than people? Check out our Denver volunteer opportunities in horticulture, and join the dedicated folks who keep our campus beautiful. You will learn about zoo horticulture while assisting with weeding, watering, mulching, and planting. Horticulture opportunities run March through October. 

Animal Health Volunteer

Searching for a Denver volunteer opportunity that puts your meal-prep skills to good use? Each of our 500+ species has a unique nutrition plan—and we can always use an extra hand in our Nutrition Center. Our animals also get specialized care at the Helen and Arthur E. Johnson Animal Hospital. Detail oriented volunteers are always needed for cleaning, room preparation, and data entry!
