Birds of Eden

Birds of Eden is the world's largest free flight aviary and bird sanctuary, located near Plettenberg Bay in the Western Cape, South Africa. The mesh dome of the sanctuary was built over 2.3 hectares (5.7 acres) of indigenous forest, and is up to 55 metres (180 ft) above ground level. 1.2 kilometres (0.75 mi) of walkways, about 75% of which are elevated, let visitors see the birds at all levels of the aviary.
