[2] Capu Tafunatu consists of alkaline rhyolite with ignimbrite facies, an igneous rock of the Monte Cinto annular volcano-plutonic complex, formed in the Permian.

[4] The inclined plane at the base of this cavity is an oblique fault which, intersecting the rocky blade of the summit, weakened it and caused it to collapse.

A few hours later, when the devil reappeared the village head gave his agreement but the bridge had to be completely built in one night, that is to say, before the rooster crowed.

In the midst of this darkness made feverish by the infernal tumult, a man walked calmly and peacefully, and contemplated the work carried out.

[7] All require great caution (risk of fatal falls) but remain practicable without special equipment for people in good physical condition and not prone to vertigo.

[7] It begins at the Moorish Pass and uses a system of low-sloping rocky outcrops (vires) that run on the east face of Capu Tafunatu: first to the south and then over whitish rocks, heading north to the plateau where the cavity opens.

[8] From the platform on the east face where the "hole" opens, a ledge crosses the north ridge, then returns to the west face towards a chimney (vertical fracture, listed II) which is climbed 12 metres (39 ft) up to near the summit ridge, to finish with a short climb (vertical slab, grade III) to the summit.
