Perisher is Australia's largest ski resort and the largest in the Southern Hemisphere, spanning 1,245 hectares across four interconnected ski areas within Kosciuszko National Park in the NSW Snowy Mountains. The combined resort links Perisher Valley, Smiggin Holes, Blue Cow and Guthega across seven peaks, serving 113 runs on terrain that rises from 1,699m to a summit of 2,054m atop Mt Perisher. The terrain breakdown skews firmly toward intermediates — 60% of runs are graded blue — though the resort's sheer scale means beginners, advanced skiers and freestylers each have dedicated zones across the mountain.

Access is via Australia's only underground rack railway, the Skitube Alpine Railway, a Swiss-designed train that departs Bullocks Flat on the Alpine Way and travels through a 6.3km tunnel — reaching 550m below the surface at its deepest point — to Perisher Valley, with a further connection to Blue Cow. Opened in 1987, the Skitube remains the defining feature of Perisher's access infrastructure and the most practical option for visitors wanting to avoid chains on the mountain road. Perisher is part of the Vail Resorts Epic Pass network, connecting the resort with Mt Hotham, Falls Creek and a global portfolio of ski destinations.
