Our post-holiday laziness is the reason to search for an easy route. That's why today we choose Plana Mountain. Our walk starts at Dolni Pasarel (a village nearby Sofia) and ends at Peiuva Buka Hut. You can find more about it in the gallery - HERE.

Geophysical methods of cave detection have, to date, reaped few positive results in finding new caves. As Atanas Rusev and Tanya Slavova report, however, this isn't inevitable. Here they describe cave detection, using ground-penetrating radar, magnetometry, gravimetry and infrared imaging, and illustrate the techniques with case studies showing the discovery of new caves and entrances.
