Michael and Quirsis Riney Primate Canopy Trails

Primate Canopy Trails is a 35,000-square-foot outdoor expansion connected to the Primate House that opened in July 2021. In warm and comfortable weather, the primates will often be seen in this outdoor space. If it is cold or rainy, they may be next door in the Primate House.

Exploring the Canopy

The $13 million exhibit consists of eight new outdoor homes for monkeys and lemurs, along with a new Primate Care Center offering indoor shelter and sleeping areas. The first-of-its-kind primate habitat and guest experience includes climbing structures that allow guests to explore the forest canopy next to the animals, while learning through play and exploration about conservation challenges primates are facing in the wild — and discovering solutions to help.


Outdoor Health

The new exhibit allows the Zoo to improve animal care, health and well-being of primates by providing access to enriching outdoor habitats, sunlight and fresh air. The 1925 Primate House, which was renovated in 1977 and will continue to be used, had few outdoor habitats available for use by only some of the species over the years. Many of the primates living at the Primate House have never had access to the outdoors until now.

SAINT LOUIS ZOO ZONE

Historic Hill

Historic Hill is a lovely stroll through one of the oldest parts of the Saint Louis Zoo. From the 1904 World’s Fair Flight Cage to the Spanish architectural flavor of the 1920s in the Bird House, Primate House and Herpetarium to the finishing touches of our thoroughly modern exhibits, this area of the Zoo has a unique ambiance and a nostalgic history that make it a great destination.
