The mountain of Trapezitsa lies to the north, Lygkos to the east and Mitsikeli to the south. The Aoos river flows to the north and its tributary Voidomatis to the southwest. Vikos Gorge is formed by the latter to the southwestern side of the mountain.

The southern and southeastern slopes of the mountain are comparatively smooth. The north side, however, forms cliffs reaching , whereas the western side is equally steep since the mountain is fragmented by Vikos Gorge.
