Petar Delchev - 27/04/2026

This is a directory of the collected data on the caves in the Main Card File of the BFSp in the Montana region, in alphabetical order by municipalities and settlements as of the date of publication. It is intended to facilitate all those interested in spelunking to know what is in the card file and what more needs to be added. The research and map material is the work of many years of cavers and spelunkers from all over the country noted, as far as is known and possible, on each sheet. The materials in the Main Card File of the caves of the Bulgarian Federation of Speleology were collected and arranged by Eng. Radush Radushev /Chichko Radush/, Zdravko Iliev /Zdravetsa/ and Ivo Tachev. Data from the Hinko card file were also used. It is important to know that GPS coordinates are taken at different times and with different accuracy. They are indicative and can give quite a serious error. The electronic version of the file can be found at caves.speleo-bg.org/.The PDF and Epub formats of this altas are at speleo-bg.org/library/. The information is available under the Creative Commons Attribution-ShareAlike license, requiring the authors to be cited at the end of each sheet. For some caves, the precise location is unknown. It has been replaced by the location of the corresponding village. The accuracy of the location of these caves is indicated with the notation "10,000 m".
