Of its many attractions, Phuket’s parks, gardens and arboretums are especially beautiful, often featuring nature trails that, in some cases, continue meandering for miles on end. The larger parks, such as the Khao Phra Taew Wildlife Sanctuary or the Sirinat National Park, are important centres for research and conservation efforts. The Khao Sanctuary, for instance, occupies 5,500 acres, much of it lush primary rainforest which is home to a diverse range of species, many of which are endangered, including monkeys, gibbons, birds, small mammals and reptiles. And for those with an interest in local marine life, the Phuket Marine Biological Centre runs the Phuket Aquarium, where many Andaman Sea species are on display, including some rare indigenous corals.
