Founded in 1922, the Houston Zoo in Hermann Park is home to more than 3,500 animals, from Asian elephants and California sea lions to okapis and Komodo Dragons. Exhibits include collections of reptiles and birds and the Wortham World of Primates, a 2.2-acre naturalistic habitat for the Zoo's orangutans and other primates. At the McGovern Children's Zoo's "contact area," visitors can experience the petting zoo. Wildlife Carousel, opened in 2004, features 64 hand-carved and hand-painted animals representing some of the world's most endangered species. Admission fee is $7 for adults, $5 for seniors, $3 for children ages 3-12 and free for children 2 and under.
