Arnhem Land covers an area of more than 96,000 square kilometres, stretching from Gove Peninsula in the north east to Cobourg Peninsula in the north west, it includes the off-shore islands of Elcho Island and Groote Eylandt (among others). The area is exceedingly beautiful, extremely rugged and contains an abundance of wildlife.
The west and south-west parts of Arnhem Land consist of rugged highlands rising over 300 metres above sea level, with steep scarps cut by deep gorges. The major river systems of the Northern Territory have their headwaters in this highland area.
