Over the years, you’ve watched your Houston Zoo undergo enormous changes and growth. Now, as we march toward our 100th anniversary in 2022, the Houston Zoo will celebrate by completing the most dramatic transformation in our history.
We will redefine what a zoo can be with beautiful and immersive habitats, compelling guest experiences, and an unyielding commitment to saving wildlife.
To create these new spaces, we are undergoing a massive construction project which will temporarily shift pathways, close buildings and move some animals to new habitats.
