Also called the Cave Museum, the Museum of Speleology & Karst is unique in Bulgaria and, possibly, the Balkans. Minerals, bottled bats, remains of ancient cave-dwelling animals such as lions and bears, are exhibited, along with displays on the Trigrad and Yagodina caves. A tape in English and German gives explanations. The museum’s in the Hotel Pesternika building, 200m up from the bus station on the hillside.
