Wadi Wurayah is home to more than 100 species of mammals, birds, reptiles and amphibians, as well as more than 300 species of plants. It is famous for its scenic waterfall set amid the Hajar Mountains. It has streams and pools dotted around the rocky outcrops. It is one of few remaining places in the world where the endangered Arabian tahr still roams free. Conservationists believe it to be among the last places in the UAE where the Arabian leopard, which has not been seen in the UAE since 1995, still survives. A footprint of a leopard was found here. The same is true for the caracal. The wadi is also home to the "Garra barreimiae", a type of freshwater fish that lives only in Al Hajar Mountains. Among the 208 species of plants is a species of wild orchid unique to the area, the "Epipactis veratrifolia". In 2018, an Indian crested porcupine was spotted here.
