There's just one place left on earth where tigers, elephants, orangutans, and rhinos live together in the wild: the Leuser Ecosystem World Heritage Site on the Indonesian island of Sumatra.

Thap Lan is Thailand’s second largest park and one of the last intact habitats for a suite of threatened and endangered species, including tigers, elephants, clouded leopards, Malayan sun bears and hornbills.
