Description

Mount Ossa (1,617 m) is the highest peak in Tasmania, Australia, located in the Pelion Range within Cradle Mountain–Lake St Clair National Park in the Central Highlands of Tasmania. Its status as Tasmania's highest mountain was confirmed by aerial survey in 1954. The mountain is composed of very old Precambrian quartzite and dolomite, giving it a distinctive rocky character unlike the volcanic peaks found elsewhere in Australia. The most common ascent is as a side trip from the Overland Track (the iconic 80 km route from Cradle Mountain to Lake St Clair), typically on Day 4 after staying at New Pelion Hut. From the junction at Pelion Gap (1,113 m), walkers follow a 2.6 km track to the summit — about 70% gradual ascent on wooden and stone boardwalks, with the final 30% involving boulder scrambling that demands care in wet conditions. On clear days the summit panorama encompasses Cradle Mountain to the northwest, The Acropolis and Mt Geryon to the south, and Walls of Jerusalem National Park to the east — among Tasmania's most rewarding viewpoints. An alternative for non–Overland Track visitors is the Arm River Track from Arm River, a longer and quieter approach. Weather can shift dramatically at any time of year.

Routes

Via Arm River Track (akses mandiri tanpa Overland Track)

Berat (jalur lebih panjang, terpencil, navigasi lebih menantang)

±8–10 jam (multi-day atau long day, bergantung titik start)

Alternatif bagi pendaki yang tidak mengikuti Overland Track berbayar. Akses dari Arm River Road di utara taman nasional, mengikuti Arm River Track melalui hutan Tasmania yang lebat hingga bertemu jalur menuju Pelion Gap lalu ke puncak. Jalur ini jarang digunakan sehingga kondisinya bisa lebih berumput dan navigasinya lebih menantang. Pendakian multi-hari direkomendasikan dengan bermalam di New Pelion Hut. Pastikan mendaftarkan perjalanan ke Parks Tasmania sebelum berangkat.

Via Pelion Gap (dari Overland Track / New Pelion Hut)

Sedang–berat (scrambling berbatu di bagian akhir; butuh keseimbangan baik)

±4–5 jam (pulang-pergi 5,2 km dari Pelion Gap)

Rute paling umum digunakan — side trip dari Overland Track pada hari ke-3 atau 4. Dari New Pelion Hut, ikuti Overland Track ke arah Pelion Gap (1.113 m, sekitar 1,5 jam dari hut). Di Pelion Gap terdapat papan petunjuk jelas menuju Mount Ossa Summit Track. Sekitar 70% jalur berupa tanjakan bertahap di atas boardwalk kayu dan batu yang melindungi vegetasi rapuh; 30% terakhir berubah menjadi scrambling di antara bongkahan batu besar. Tidak ada jalur pita merah di bagian puncak — navigasi dengan cairn. Dari puncak, pemandangan 360° menampilkan Cradle Mountain, The Acropolis, Mt Geryon, dan Walls of Jerusalem.

Climbing Experiences

Climbing Mount Ossa is typically done as a side trip from the Overland Track on Day 4, branching from Pelion Gap after staying at New Pelion Hut. The 5.2 km one-way trip and 500 m of gain from Pelion Gap (1,113 m) to the summit (1,617 m) takes 4–5 hours return. Hikers describe the trail as gradual at first on wooden and stone boardwalks, transitioning to boulder scrambling in the final 30% that demands care. Summit views encompass Cradle Mountain, The Acropolis, Mt Geryon, and Walls of Jerusalem National Park — a worthy reward. Those not on the Overland Track can approach via the Arm River Track.
