Gariwerd and the Grampians National Park has been a popular destination for recreation and tourism since the middle of the nineteenth century. According to Wilkie, the extension of railways to nearby Stawell, Ararat and Dunkeld were an important factor in the mountains' increasing popularity in the early twentieth century; growing car ownership and the construction of tourist roads in the ranges during the 1920s were also significant.
Gliding Mount William is known within the gliding community for the "Grampians Wave", a weather phenomenon that sometimes enables glider pilots to reach extreme altitudes of the order of . This predominantly occurs during the months of May, June, September and October when strong westerly winds flow at right angles to the ridge, and produce a large-scale
standing wave.
Rock climbing The Grampians is a famous
rock climbing destination, with the first routes being established in the 1960s. Notable routes include
The Wheel of Life (V15 / 35) and
Groove Train (33) which attract world class climbers. Australian adventurer
Jon Muir regards the Grampians, along with the Arapiles, as near perfect in their combination of access, climate and type of rock. In March 2019, 30% of climbing areas were closed by
Parks Victoria due to cultural and ecological concerns, namely bolting, chalk marks, and making access paths through vegetation. It closed 70% of bouldering routes, and 50% of sport climbing. Parks Victoria were accused by climbers of exaggerating damage and acting heavy handedly by pitting them against
traditional owners, of whom they are "natural allies". Jon Muir and renowned Australian mountaineer
Tim Macartney-Snape have criticised Parks Victoria’s handling of the situation, with Muir saying, “The climbers haven’t really been taken into the equation”, and Macartney-Snape saying, “It’s really the way it has been managed. It’s a blight on Australian administration of natural land.” The trail, which takes inspiration from popular Tasmanian trails, is designed to take 13 days to walk and crosses the length of the park. It was officially opened on 12 November 2021. 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". In spring, the Grampians wildflowers are an attraction. Colloquially known as the ‘garden of Victoria’, the Grampians is home to 975 native plant species (including more than 75 orchid species), representing one third of the total Victorian flora, and many of these species are only found in the Grampians, including the Grampians pincushion lily (Borya mirabilis), one of the rarest native lilies in Australia.
Food and Wine Festival Grampians National Park is home to one of Australia's longest running food and wine festivals,
Grampians Grape Escape, held over the first weekend of May in
Halls Gap every year. Launched in 1992, the
Grampians Grape Escape is a hallmark event for Victoria and provides food and wine offerings by more than 100 local artisan producers, live music and family entertainment. ==Natural disasters==
