Wolfe Creek Crater National Park
The almost perfectly circular crater, some 880 m (2887 foot) in diameter and 60 m (196 feet) deep, forms the focus of the Wolfe Creek Crater National Park.
Oh, and chill out - the movie Wolf Creek is completely fictional.
Wolfe Creek Crater was only discovered by science in 1947 as a result of aerial surveys. The feature had been known to local Aborigines since time unknown, under the name Kandimalal.
It is thought that the crater was formed some 300,000 years ago when a meteor weighing in excess of 50,000 tonnes (55,116 tons) impacted the earth's surface at 15 km/s (9.3 mi/s).
The crater partly inspired the name and setting of a 2005 horror film, Wolf Creek, depicting serial killings in the Outback regions of Australia.
Whilst toilets exist at the site, note that there is no water made available at the crater.
Flora and fauna
Wolfe Creek Crater is located some 145 km south-south-east of Halls Creek via an eastern offshoot of the Tanami Track to Alice Springs (gravel, only accessible to conventional vehicles during the dry season from May-October). Look for signs to the crater. The drive takes 2-3 hours to complete and should only be undertaken after notifying the authorities of travelling intentions and with sufficient water reserves.
Sightseeing, walking, photography, nature observation. Viewing from the crater rim is a must.
An alternative, spectacular way to view the crater is to take an aerial flight from Halls Creek.
A camping ground is available within the National Park.
