The entrance to the cave is approximately  high and  wide. Inside the apex reaches a height of  with a floor area of about   Two large stalactites hang down from the roof like large pens, hence the cave's name. History
A number of inscriptions carved into the walls of the cave are believed to date to the Yuan Dynasty (1271–1368). One of these refers to the precise date of 1283 CE. Luobi Cave is later mentioned in Ming Dynasty records for Hainan () compiled at the time of the Zhengde Emperor (r. 1505–1525 CE) which note the cave's stalactites and their unending flow of water. Archaeological finds
Between 1992 and 1993, archaeologists carried out a comprehensive excavation and survey of the Luobi Cave over an area of . They discovered eight fossilised human teeth, stone and bone tools, as well as several hundred fossilised animal bones, more than 70,000 sea shells and evidence of ancient fires. Radiocarbon dating techniques show that the finds are from the late Upper Paleolithic era around 10,000 years ago and represent the earliest evidence of human activity in Hainan as well as the southernmost occurrence of stone tools from this period. Very few fossilised fish bones were discovered at the Luobi site, indicating that the inhabitants of the cave had yet to master the skill of fishing. The few fish they did obtain were probably found in rocky pools along the coast having been swept ashore. Since 2001 the Luobi Cave has been a national protected cultural site. Folklore
According to legend, anyone coming into contact with water dripping from Luobi Cave's stalactites will become a talented writer whilst a number of large flat rocks scattered across the floor of the cave are said to be inkstones once used by Taoist Immortals. The smaller Xianlang Cave () nearby is claimed to have been the home of female immortal who descended from heaven and married a man from the local Li minority. See also
