Hannels Spur Track (23km)

Hannels Spur Track is a demanding yet deeply rewarding 23-kilometre journey through the rugged beauty of Kosciuszko National Park, New South Wales. Classified as a grade 5 hike, it typically takes two to three days to complete and is widely regarded as one of the most challenging treks in New South Wales. Its difficulty lies not only in the relentless ascent – the greatest elevation gain of any tracked spur in the country – but also in the need for strong navigation skills through remote wilderness. Despite its challenges, the trail’s rich history and striking natural diversity make it an extraordinary experience for those prepared to tackle it.

Starting near Geehi Flat on the Alpine Way, the hike begins with a clear marker indicating the route to the summit of Mount Kosciuszko, 15.5 kilometres ahead. However, for those continuing beyond Australia’s highest peak, this trail extends to Thredbo alpine village, offering a full and immersive experience of the Snowy Mountains' western slopes.

The Hannels Spur Track is unparalleled in Australia, boasting the country’s greatest elevation gain of 1,800 metres. As you ascend, the landscape transforms dramatically, carrying you from dense forests near the Geehi and Swampy Plain Rivers to sub-alpine woodlands and, eventually, to the windswept alpine zones of the Main Range. Along the way, the shifting vegetation paints a vivid picture of the Snowy Mountains' ecological complexity, making the climb as captivating as it is physically demanding.

This trail also holds a significant place in history. It retraces the path taken in 1840 by Polish explorer Paul Strzelecki, James McArthur, and their Aboriginal guides, who led Strzelecki to become the first European to ascend and name Mount Kosciuszko. Walking in their footsteps, you feel a sense of connection to the explorers and the traditional custodians of this land, whose knowledge and resilience are inextricably tied to this terrain.

For decades, the Hannels Spur Track was favoured by mountaineers preparing for Himalayan expeditions, particularly for its relentless ascent through remote wilderness. While the 2003 bushfires left the trail nearly impassable, dedicated work by the National Parks and Wildlife Service (NPWS) and volunteers in 2018 restored much of the route. Clearing efforts reopened the trail to its full length, though it remains a formidable challenge best suited to experienced hikers and trail runners.

The climb to Byatts Camp, which lies approximately 1,350 metres above the starting point, is steep and demanding. From there, the journey grows even more challenging as the marked path gives way to 3-4 kilometres of uncleared footpad through alpine heath above the tree line. Cairns provide some guidance south from Byatts Camp and around Abbott Ridge to the Wilkinson Creek valley. However, hikers must exercise caution, particularly when navigating the exposed ridges where weather can change in an instant.

Preparation is key for anyone tackling this track. A detailed map, compass or GPS, and a personal locator beacon (PLB) are essential, as mobile reception is unreliable. Proper clothing for all conditions, emergency shelter, and ample provisions are also a must. While the rewards of the Hannels Spur Track are many – from breathtaking views to the satisfaction of conquering Australia’s toughest climb – the trail demands respect, experience, and careful planning.

For those prepared to take on the challenge, this hike offers an unparalleled connection to the raw beauty of the Snowy Mountains, a glimpse into Australia’s mountaineering legacy, and a journey that stays with you long after the final step into Thredbo.
