History
The cave was first explored in 1963. Municipal information records later surveying and periods of tourist use, with renewed management by the Asenovgrad municipal tourism operator from 2018. The cave contains stalactites, stalagmites and sinter formations, and a small bat colony is also recorded.
Good to know
The driving estimate is to the Dobrostan/Martsiganitsa approach area; the final section is on foot. Opening is seasonal, so check the official municipal information before travelling.
