Cheyenne Mountain Zoo is one of the treasures of Colorado Springs, sitting at 6,800 feet above sea level. One of the favorite destinations of Colorado locals and visitors from all over, this zoo got its start in 1926. It was once the home for a private collection of exotic animals, but it's now is home to close to 1,000 animals, with more than 200 species residing in this picturesque setting. Zoo patrons can feed giraffes, ride the carousel or Sky Ride, or enjoy the art exhibits that are intertwined in some of the animal exhibits.

Denver Zoo is a beloved part of the city and takes up 80 acres in the heart of City Park. Indoor and outdoor exhibits, as well as special events and educational opportunities, make this a favorite destination for so many who come to Denver. This zoo began with just one black bear and was the first zoo in the country to use an open-air naturalistic enclosure (Bear Mountain) instead of caged or barred-in exhibits. The zoo works hard to provide amazing care to the animals and be a green zoo.
