Hoteles cerca de Cueva de Postoina, Postojna

If you like to explore geological wonders, Postojna Cave is just brilliant. Hop on the small electric train that slinks its way through this vast underground network of karst caves, where huge stalactites seem to drip from the ceiling. Keep your eyes peeled for the stand-out stalagmite, the 50,000-year-old formation aptly named ‘Brilliant’.
