Pueblo Zoo originates in three places, all within the city of Pueblo. At the start of the 20th century, three parks around the town displayed a menagerie of exotic animals, but during the 1920s, the zoo consolidated in the current 25-acre City Park location. The space gradually improved throughout the Great Depression as the Works Progress Administration added an animal house, tropical birdhouse, and bear pits. Now open year-round, the zoo houses its 120 different species in modern facilities, allowing visitors to peer at boa constrictors in the rainforest exhibit or watch penguins dive from an underwater viewing room. Favorite animals on display include playful otters and penguins as well as the majestic african lion.
