The Grampians National Park (also Gariwerd) is a national park in Victoria, Australia, 235 kilometres west of Melbourne. The Park was listed on the Australian National Heritage List on 15 December 2006 for its outstanding natural beauty and being one of the richest indigenous rock art sites in south-eastern Australia.
The Grampians feature a striking series of sandstone mountain ranges. The ranges were named in 1836 by Surveyor General of New South Wales Sir Thomas Mitchell after the Grampian Mountains in his native Scotland, but are also known by the name Gariwerd, from one of the local Australian Aboriginal languages, either the Jardwadjali or Djab Wurrung language. After a two-year consultation process, the park was renamed Grampians (Gariwerd) National Park in 1991, however this controversial formality was reversed after a change of state government in 1992. The Geographic Place Names Act 1998 reinstated dual naming for geographical features, and this has been subsequently adopted in the Park based on Jardwadjali and Djab Wurrung names for rock art sites and landscape features with the National Heritage List referring to Grampians National Park (Gariwerd).
This area is a distinct physiographic section of the larger Western Victorian Highlands province, which in turn is part of the larger East Australian Cordillera physiographic division. The general form that the ranges take is, from the west, a series of low-angled sandstone ridges running roughly north-south. The eastern sides of the ridges, where the sedimentary layers have faulted, are steep and spectacular, beyond the vertical in places - notably at Hollow Mountain near Dadswell's Bridge at the northern end of the ranges. The most popular walking area for day trippers is the Wonderland area near Halls Gap. In summer the ranges can get very hot and dry. Winter and spring are the best times for walking. The Wonderland area is also host to "The Grand Canyon" on the "Wonderland Loop" on one of the tracks to the "Pinnacle".
