Duhlata cave is the longest (18 km in length) cave in Bulgaria, located in Bosnek karst area. Its 8 underground rivers flow is several times less than the surface springs flow, and probably more underground rivers and cave galleries are still undiscovered. For many years in Pepeliankata cave, located nearby, have been made attempts to discover its lower levels and to penetrate in new cave galleries and underground rivers that also stems from the same springs. Ground Penetrating Radar is used, for the first time in Bulgaria, to locate new cave entrances and galleries close to the surface, nearby Peleiankata Cave. Several possible new cave entrances and a cave room were located after analyzing results from the GPR’s radagrams.
