A further 50 metres (160 ft) of pitches leads to an extensive horizontal development called Subsoil. Subway Level, the lowest stratigraphical layer of the cave, can then be reached by descending 100 metres (330 ft) down the Four Pitches of the Apocalypse.

Most other explorations begin at entrance E, which leads through an awkward crawl to a 30-metre (98 ft) pitch that has a deposit of snow at the bottom most years. From here extensive horizontal levels of Swings and
Roundabouts, Treeumphant and Rhino Rift can be reached. Descending 150 metres

As of 2013, the cave has six entrances, has passages of 18.6 kilometres (11.6 mi) in length and a depth of 622 metres (2,041 ft). There are over 300 question marks (unexplored leads) of varying quality in the cave.
