The Horn, Mountain summit in Mount Buffalo National Park, Australia.

The Horn is a granite summit in Mount Buffalo National Park featuring exposed rock faces and steep cliffs that dominate the surrounding plateau. The rocky terrain creates natural viewing points across the landscape below and toward distant mountain ranges.

The Mount Buffalo plateau was named in 1824 by the explorers Hamilton Hume and William Hovell, who thought its shape resembled a buffalo. The name was given to the plateau, not to The Horn itself, and no source records a first European ascent of the summit.

Aboriginal people made summer ascents of Mount Buffalo to gather bogong moths, which cluster in rock crevices and are rich in protein, and to meet and hold ceremonies. The mountain's name comes from the plateau, named in 1824 by the explorers Hume and Hovell for its supposed resemblance to a buffalo.

The route to the summit follows a marked walking track with steel stairs and viewing platforms from the car park area. The path is relatively short and straightforward, though sturdy footwear helps and wet weather can make surfaces slippery.

From the peak, visitors can see far across the region on clear days and spot neighboring mountains like Mount Bogong and Mount Hotham. The 360-degree views from this location make it one of the best points for understanding the layout of the mountain range.
