The site is characterized by jagged peaks, large rock walls and pine trees twisted by the wind.

Located in the centre of the "Massif de Bavella", are the seven "tours d'Asinau," or towers of Asinau, the actual "needles".

It extends from the forest of Tova and the town of Solaro to the 1381m Monte Calva to the south, the edges of the Massif de l'Ospedale, and almost to Conca and the sea in the east.

[2] After the Bavella pass, the path begins its descent towards Conca, via "Foce Finosa" (1206 m) and the i Paliri refuge (1055 m) at the foot of the Punta Tafunata (literally "Pierced Peak"), a 1312 m high mountain with a hole.

A statue of Notre-Dame-des-Neiges ("Our Lady of the Snows") stands at the pass, a few meters from the road, on top of a large mound of boulders.
