Tiger Valley is made up of three distinct areas: the enclosures of the Siberian Tiger and the Sumatran Tiger, and, in the centre, the temple, a covered area designed to inform visitors and raise awareness about these species.

As you climb the steps of Tiger Valley, you will find eight large vertical acrylic tubes filled with polystyrene balls. Each one represents a tiger subspecies, and the level to which it is filled indicates how many animals of that subspecies remain in the wild.

You will notice that three of the tubes are empty. This means that three subspecies are extinct: the Bali Tiger, the Caspian Tiger and the Javan Tiger. As for the two species found at Lisbon Zoo, it is estimated that only 480 Siberian Tigers and 400 Sumatran Tigers remain in the wild, with the former classified as "Endangered" and the latter as "Critically Endangered".

In this area, you will also learn that there are only around 6,000 tigers left in the wild across all subspecies, as well as discover their characteristics and the main threats they face.
