Verdant gardens and open-environment animal enclosures are hallmarks of this world-renowned zoo, which is 4 km (2½ mi) north of the city center. A lion park, reptile house, and butterfly pavilion where more than 1,000 butterflies flutter through the rain-forest setting are on site, as is a simulated African rain forest where a group of Western Lowland gorillas lives. The spectacular Trail of the Elephants, home of seven Asiatic elephants, has a village, tropical gardens, and a swimming pool. The orangutan sanctuary and baboon outlook are other highlights. It's possible to stay overnight with the Roar 'n' Snore package (A$195 per adult) and enjoy dinner, supper, breakfast, close encounters with animals, and a behind-the-scenes look at the zoo's operations. Twilight jazz bands serenade visitors on summer evenings. Children are free.
