It is located in the Hala spot approximately 1.5 km from the north-eastern coast, facing the open sea to northeast.

Clearly visible from the sea, but difficult to access, it is situated at an altitude of 350 m. The about-2-km-deep cave has a main passage with a mean width of 50 m and a mean height of 20 m. Sunlight reaches about 200 m from the entrance.

A range of epigraphy from the 1st to the 6th century CE has been recorded in the back part of the cave, placing Socotra as a major hub in the overseas trading links in ancient times, where merchants from all coasts of the northern Indian Ocean were brought together.

[3] In 2001, a group of Belgian speleologists from the Socotra Karst Project mapped and investigated the cave, finding numerous graffitis and drawings on speleothems and floors.

The corpus of inscriptions is in Indian Brahmi, South Arabic, Ethiopian Geʽez, Ancient Greek, Palmyrene, and Bactrian scripts.
