For more than a century, Woodland Park Zoo has been displaying and protecting some of nature's most endangered animals. Spread across 92 acres and home to more than 1,090 animals, the park educates and entertains the public with all manner of exhibits. Traipse through the Tropical Rain Forest, which mimics the atmosphere of the African and South American rain forests, and provides homes for red ruffed lemurs, gorillas, colobus monkeys, and jaguars.

The Raptor Center introduces zoo-goers to the majesty of predatory birds including hawks, falcons, and owls, whose flight demonstrations (running through September 30) entertain guests and taunt flightless penguins. Re-creating the vast grasslands of eastern Africa, the African Savanna exhibit ushers adventurers through a landscape of rare and interesting species such as giraffes, zebras, and hippos, as they live alongside with lions and wild dogs.
