The trails pull off a strange trick. They feel genuinely alpine and faintly Outback-vast, all big sky and treeless rolling tops, yet the ski villages of Thredbo and Charlotte Pass sit close at hand with hot food and warm clothing for sale. That nearness can lull you. Snow regularly drapes these paths, almost guaranteed in winter and lingering on the final stretch even in summer. Storms blow in off the Main Range with little warning, hurling gusts that can top 150 kilometres an hour and dropping visibility to nothing. In the warm months the essentials are modest: water, a jacket, sturdy shoes. In winter the same walk becomes serious country, demanding a topographic map, real boots, and the humility to turn back when the weather says so.

The most popular route starts above the trees. The Kosciuszko Express Chairlift lifts you out of Thredbo to the Top Station at around 1,930 metres, and from there a raised steel walkway leads roughly six and a half kilometres to the summit. The first stretch is laced with little meltwater waterfalls spilling on both sides of the path. You climb gently past lookouts, dip to cross the infant Snowy River near its very source, then rise toward Rawsons Pass, where the path from Charlotte Pass joins yours. The last stretch to the top is the steepest and most exposed, spiralling up the flank of the mountain to the trig point. Stand there and you have climbed a Seven Summit, with the whole rumpled roof of Australia falling away around you.

Partway along, a modest plaque marks the Cootapatamba lookout, easy to miss if you are not watching the left side of the trail. It overlooks Lake Cootapatamba, a tarn scooped out by ancient glaciers and held at 2,048 metres, the highest lake on the Australian mainland, sitting only about 800 metres south of the summit itself. The glaciers that carved it are long gone, but the shape they left behind is unmistakable, a cold blue eye in the rock. The name comes from the local Ngarigo language. Stopping here is a reminder that this rounded, walkable mountain has a deep-time geology to match the granite drama of any sharper peak; it simply wears its history more quietly.

Every landmark up here carries a story. The mountain itself was named in 1840 by the Polish explorer Pawel Strzelecki, who climbed to the top and honoured Tadeusz Kosciuszko, a hero of both the Polish struggle for independence and the American Revolution, so that Australia's highest point bears the name of a freedom fighter from the other side of the world. On the longer Charlotte Pass route stands Seamans Hut, built of stone in 1929 as a refuge and a memorial to two skiers, Laurie Seaman and Evan Hayes, who died in a blizzard on these slopes, a sober note in a landscape that can turn deadly fast. Long before any of these names, the Ngarigo people and their neighbours walked this high country each summer, following the bogong moths to the peaks. The walk to the summit traces a path far older than its maps.
