Tidbinbilla Nature Reserve is a
protected area, on the fringe of
Namadgi National Park, that is a short drive from the city of
Canberra, in the
Australian Capital Territory, the
capital city of
Australia. The nature reserve consists of a large valley floor, the Tidbinbilla Mountain and the Gibraltar range. The sides of the valley are steep and relatively undisturbed; the lower slopes are partly cleared and have a history of
Aboriginal and European use. Tidbinbilla Mountain is believed to have been used for initiation ceremonies. The word 'Tidbinbilla' is Aboriginal in origin and is derived from the word
Jedbinbilla – a place where boys become men.
