The Mount Ossa Circuit is a challenging multi-day trek in the heart of Tasmania's Central Highlands, offering a true wilderness experience and the chance to summit the state's highest peak. This circuit, typically undertaken over two to three days, traverses a landscape of dramatic alpine scenery, including rugged mountains, pristine glacial lakes, and vast, windswept plateaus. It is a route for experienced hikers seeking solitude and a significant physical challenge, rewarding them with unparalleled views and a profound connection to the wild Tasmanian wilderness. The circuit is renowned for its demanding terrain, unpredictable weather, and the sheer majesty of its alpine environment.
The Mount Ossa Circuit is a demanding but immensely rewarding trek that takes you to the roof of Tasmania. Starting from the shores of Lake St Clair, the circuit winds its way through diverse alpine terrain, culminating in the ascent of Mount Ossa, which stands at 1617 metres. The trail is not a clearly defined, well-trodden path in many sections, requiring strong navigation skills and a good sense of direction. It is a route that demands respect for the alpine environment, with weather capable of changing dramatically and rapidly.
The journey typically begins with a walk along the shores of Lake St Clair, Tasmania's deepest lake, before heading inland towards the rugged peaks. The ascent to Mount Ossa is steep and often involves scrambling over scree and rock. The summit offers breathtaking 360-degree views across the vast wilderness of the Cradle Mountain-Lake St Clair National Park, including views of Cradle Mountain itself, Barn Bluff, and the central plateau. The descent often follows a different route, allowing for a varied experience of the park's alpine landscapes, including alpine meadows, rocky outcrops, and potentially snowfields even in early summer.
This circuit is best suited for those with a high level of fitness, experience in alpine environments, and proficiency in navigation using map and compass. It is a true test of endurance and self-reliance, offering a profound sense of accomplishment upon completion. The remoteness and ruggedness of the terrain ensure that walkers are likely to experience a true sense of solitude, making it an ideal choice for those seeking an escape into the wild.
The Central Highlands of Tasmania, including the area around Mount Ossa, have a long and complex history. For millennia, Aboriginal Tasmanians, particularly the Paredarerme people, traversed these highlands, utilising the rich resources of the alpine and subalpine environments. These journeys were often seasonal, following traditional pathways and utilising the abundant flora and fauna for sustenance and tools. The rugged terrain and harsh climate would have presented significant challenges, highlighting the resilience and adaptability of the original inhabitants.
European exploration and settlement in the region began in the 19th century, driven by pastoralism, mining, and later, tourism. The establishment of the Cradle Mountain-Lake St Clair National Park in the mid-20th century was a crucial step in preserving this unique wilderness. Mount Ossa, as the state's highest peak, has long been a significant landmark for explorers and mountaineers. Early ascents would have been arduous expeditions, requiring considerable courage and determination, often undertaken by surveyors, geologists, and adventurous individuals seeking to chart and conquer the highest points of the island.
The development of walking tracks and huts in the broader region, while not as extensive or formalised as on some other famous Australian walks, has facilitated access for hikers. However, the Mount Ossa Circuit itself remains a route that largely relies on off-track navigation and a deep understanding of the alpine environment. The area continues to be a place of immense natural and cultural significance, a testament to the enduring power of Tasmania's wild landscapes.
The Mount Ossa Circuit is a true alpine experience, and its accessibility and conditions are heavily dictated by the seasons. The best time to undertake this challenging trek is during the warmer months, from November to April. During this period, the days are longer, and the weather is generally more stable, although still highly unpredictable.
Summer (December to February): This is the most popular time for hiking in the region. Snowmelt usually means water is readily available, and the alpine wildflowers can be in bloom. However, summer can also bring thunderstorms, high winds, and sudden drops in temperature. Sandflies can also be prevalent, especially near water sources.
Autumn (March to April): The autumn colours in the Tasmanian highlands can be spectacular, with golden hues transforming the landscape. The weather can be crisp and clear, offering excellent visibility. However, temperatures begin to drop significantly, and the possibility of early snowfalls increases, particularly at higher elevations. Days are shorter, requiring careful planning of hiking times.
Spring (November): Early spring can still see significant snow cover on Mount Ossa and surrounding peaks, making navigation and travel difficult and potentially dangerous. While wildflowers may begin to appear, conditions can be highly variable, with a higher chance of snow, ice, and strong winds. It is essential to check conditions thoroughly before setting out.
Winter (May to October): This period is generally unsuitable for the Mount Ossa Circuit for all but the most experienced winter mountaineers. Heavy snow, ice, extreme cold, and short daylight hours make the trek exceptionally dangerous. Avalanche risk is also a significant concern. Access to the trailhead may also be affected by snow.
Weather: It cannot be overstated that the weather in Tasmania's alpine regions is notoriously fickle. Conditions can change from clear and sunny to blizzard-like within a matter of hours. High winds, heavy rain, sleet, and snow are common, even in summer. Walkers must be prepared for all conditions and carry appropriate gear for survival in extreme weather.

Important Notes:
The Mount Ossa Circuit is a serious undertaking that requires meticulous planning and preparation. Given its challenging nature and the remoteness of the terrain, a high level of fitness is non-negotiable. You should be comfortable hiking for extended periods with a heavy pack over uneven and steep ground. Familiarity with map and compass navigation is essential, as large sections of the route are not marked and can be difficult to follow, especially in poor visibility.
The closest major town with comprehensive services is Launceston, approximately 2.5 hours' drive from the Lake St Clair trailhead. Launceston offers a full range of accommodation, outdoor gear shops, supermarkets, and transport options. It is advisable to spend at least one night in Launceston before heading to the trailhead to finalise gear, purchase supplies, and check weather forecasts. Ensure your vehicle is in good condition for the drive, as services are limited once you leave the main towns.
It is crucial to inform someone of your detailed itinerary, expected return time, and emergency contact details. This is a fundamental safety precaution for any remote wilderness trip.
The Mount Ossa Circuit does not have a continuous chain of designated huts like some more developed tracks. The primary accommodation option for those undertaking the circuit is camping. However, there is a key hut that walkers may utilise or pass by:
Pelion Hut: This is a basic hut located on Pelion Plains, a popular stopover point for those walking the Overland Track. It is a serviced hut with bunks, a fireplace, and a rainwater tank. However, it is essential to understand that Pelion Hut is part of the Overland Track system and requires advance booking through Parks Tasmania, especially during the peak season (October to May). If you intend to use Pelion Hut, booking is mandatory.
Camping: Outside of Pelion Hut, the circuit involves camping in designated or suitable wild camping locations. Walkers must adhere strictly to Leave No Trace principles, camping at least 100 metres from water sources and established tracks, and ensuring minimal impact on the environment. There are no formal campsites with facilities along the majority of the circuit route. You will need to be entirely self-sufficient for camping.
What's NOT provided:
Seasonal Availability: Pelion Hut is generally accessible year-round, but booking is required during the peak season. Camping is possible year-round, but winter conditions make it extremely hazardous and generally not recommended.
Costs: Hut fees for Pelion Hut are part of the Overland Track booking system and are typically around AUD $60-80 per person per night during the peak season. Camping fees may also apply in certain areas, and it is essential to check with Parks Tasmania. A National Parks Pass is also required for entry into the Cradle Mountain-Lake St Clair National Park.
Entry into the Cradle Mountain-Lake St Clair National Park requires a Parks Pass. These can be purchased online from the Parks Tasmania website or at various visitor centres and outlets. For multi-day hikes, an annual pass is often the most economical option.
