In a mere ¾ mile trek, a visitor to the Gladys Porter Zoo will encounter a diverse ensemble of 377 species of animals and 225 species of plants. The park is divided into four zoogeographic areas: Africa, Asia, Tropical America and Indo-Australia. There is also a Herpetarium and Aquatic Wing, a Free-flight Aviary, Macaw Canyon, Bear Grottos, a California Sea Lion exhibit and Komodo dragon exhibit. Small World features a nursery and an animal contact yard where children can touch and interact with domesticated animals. Large numbers of wild birds find sanctuary on the Zoo grounds, drawn to the plants and waterways that provide them with food and shelter.

Take a virtual tour of the Gladys Porter Zoo.

Tropical America
Tropical America represents a region that includes all but the northernmost part of Mexico, all of Central America and the northern two-thirds of South America. This extremely lush area is home to an incredible variety of plants and animals; nearly one-half of all known species on earth live in this region. In the Gladys Porter Zoo's Tropical America, visitors can view Macaw Canyon, Galapagos Tortoises, Caribbean flamingos, spider monkeys, Cuban crocodiles, and dozens of other unique and rare animals from the tropics.

Indo-Australia
This area of the Zoo represents the regions of Indonesia, the Philippines, New Guinea, Australia and New Zealand. In this area, Zoo visitors can view orangutans, tree kangaroos, kookaburras, Philippine and saltwater crocodiles, agile wallabies, and magpie geese, along with many other creatures native to Austrailia. This region of the Zoo also features our Indo-Australian Walkabout an interactive aviary.

Asia
The continent of Asia is a land of extremes and unbelievable diversity. It's unsurpassed range of elevations, latitude and climatic influences produce the greatest variety of habitats on any continent. In the Gladys Porter Zoo's Asia, one can find such animals as gaur, Przewalski's horses, Bactrian camels and pileated gibbons.

Africa
Some of the more popular zoo animals are representatives from Africa. This Zoo exhibits some of its more familiar animals, like reticulated giraffes, Grant's zebras, African lions, ostrich, Western lowland gorillas, chimpanzees and white rhinos, along with some of the not-so-familiar animals such as Arabian oryx, greater kudu, cape hunting dogs, bontebok and bongo.

Small World
This section features a contact yard, baby animal nursery, and various exhibits themed to small, baby and miniature species of animals. In the contact yard, visitors can experience close encounters with some of the Zoo's inhabitants such as Nigerian dwarf goats, miniature mules and domestic, minor breed chickens. The nursery contains any new Zoo baby that needs special care or hand-rearing.

Herpetarium and Aquatic Wing
In the Herpetarium, visitors will find some of nature's most intricate patterns and unique shapes! One can check out a giant Reticulated python or try to tell the difference between a venomous coral snake and a harmless Mexican milksnake. Additionally, there are many different species of lizards, turtles, and even some very rare crocodilians on display in the Herpetarium. Old favorites like rattlesnakes, boa constrictors and gila monsters join with baby radiated and star tortoises, crocodile monitors and eyelash vipers to make a truly diverse exhibit of herpetofauna. The Aquatic Wing houses both fresh and saltwater fish from around the world with emphasis on specimens found in the Texas Gulf of Mexico area, local estuaries, fresh water lakes and resacas.

Bear Grottos & California Sea Lions
The bear grottos are naturalistic rock enclosures with caves and waterfalls, where sun bears and spectacled bears can play in the water or spend a lazy afternoon just napping in the sun. Adjacent to the lively bears are the California sea lions. Visitors can watch these playful pinnipeds splashing and swimming about for hours.

Free-Flight Aviary (Currently Closed for Renovation)
A walk through the free-flight aviary will reveal dozens of unusual and colorful birds in a tropical rainforest habitat. Visitors can observe such beautiful birds as roseate spoonbills, scarlet ibis, white-cheeked turacos and golden pheasants.

A replica of a real canyon in the Mexican state of Tamaulipas, this area of the Zoo provides 56,000 cubic feet of free-flight space for military and blue and yellow macaws. Additionally, this spacious exhbit is home to crested caracaras and king vultures.

Indo-Australia Bird Walkabout
Zoo guests entering the exhibit will meander along a horseshoe-shaped pathway around a sculpted rocky outcropping topped with an artificial tree and a trickling waterfall. And on designated days of the week, a nearby sales kiosk will offer small portions of seed and other bird treats so that the public, is they so desire, will be able to feed the birds.

IRealm of the Dragon
The Zoo's newest exhibit is the Realm of the Dragon, featuring the rare Komodo dragon. The unique and endangered species is the largest monitor in the world and can attain lenghts of 10 feet; adult males can weigh over 220 pounds.

Birding in the Zoo
Many Zoo visitors are surprised to learn how many of the birds they see in the Zoo are not in our collection. The Zoo is not just a collection of animals. It is a sanctuary, where wild animals find refuge and often places to nest. Wild birds commonly found on Zoo grounds are chachalacas, egrets, herons, red-crowned parrots, great kiskadees, kingfishers, cormorants and woodpeckers.

Botanical Garden
A walk through the grounds of the Gladys Porter Zoo can be as much of a botanical experience as it is a zoological one. Among the many groupings of plants, is the cactus garden, which highlights cactus and other succulents from all over the world, including saguaro, barrel cactus and aloe vera. Equally fascinating are such plants as the Hong Kong orchid tree, royal poinciana, silk floss tree, shaving brush tree, and the most popular of flowering vines, the bougainvillea.
