The Clifden Limestone Cave System is in the Western Southland Region of New Zealand, on private land close to the hamlet of Clifden.[1]
The cave is formed in Miocene limestone created from the accumulation of shell fragments, sand and pebbles in the Epeiric Zealandia sea. It is a solutional cave.
Glow worms or titiwai (Arachnocampa luminosa) find a natural habitat in the Clifden Cave System because of its damp environment with little or no wind.[2]
The cave system runs about 300m (1,000feet). A marked through route with fixed ladders is available for properly equipped people who wish to experience caving, and other passages are accessible for experienced cavers.
