A construction in the manner of a hut measuring 4.7x6.2 metres with a grille door protects the mouth of the cave. This gives way to a vertical drop of 7 metres. This places us in a chamber 27x15 metres, with the floor occupied by medium-sized blocks and sloping towards the west. The cavity continues descending with a steep slope, forming a ramp-like gallery with an irregular layout. In this way one reaches a low ceiling passage where one must crouch momentarily to get through it. On the other side, the cave regains its dimensions until, shortly after, reaching the widest and most comfortable point of the cave; this is a chamber with a fairly flat floor, with maximum dimensions of 36x18 metres, although it is subdivided by some stalagmitic masses.

For their spectacular nature, some colonnades located in the N sector of the chamber stand out. The stalagmitic masses give the sector a particular beauty; these formations stand out for their black colouration, produced very probably by the contribution of manganese oxide.

The 7-metre vertical drop is overcome by means of a metal ladder with a handrail installed permanently. Two sections of fixed ladder help to overcome the most committing passages. At the beginning of 1990 the access to the cavity was already arranged with the metal ladder and the rope handrails, but the track still did not reach the mouth; this was made in 1994 and later the hut was built.

Toponymy: The word ormini, bulurmini, oli ermí, olimini, boli ermini, which we find in different cavities of the region, as well as bolumini or bolimini in others in the País Valencià, seems to come from the Bol armeni, a type of reddish clay that together with other substances formed a paste that was used to gild objects. It is also known that in the País Valencià it was used for pharmaceutical purposes. It is unknown whether this type of material was extracted from the cova de l'Ormini or whether it is merely attributed by popular imagination.
