Plešivec, Mountain and conservation area in Kamýk, Czech Republic.

Plešivec is a 510-meter mountain within the Bohemian Central Mountains that sits within a protected area due to its natural habitats and geological interest. The slopes show different rock formations and soil types that define the character of the local landscape.

Basalt was quarried on Plešivec until 1945, leaving the slopes shaped by extraction. On 14 October 1966 the whole hill was declared a nature monument over 32.65 hectares, protecting the scree fields with their circulating air, permanent ice pits and ventaroles, whose stability depends on old lime trees.

The name Plešivec is also borne as Ledový vrch (Ice Mountain) and locally Jordán, German Eisberg. On the southern slope stands the Baroque Chapel of St John the Baptist, built in 1660, surrounded by centuries-old oaks. The slopes are forested with oaks and hornbeams, with lindens near the summit.

The mountain is accessible year-round, with marked paths reaching various viewpoints that overlook the surrounding landscape. Visitors should wear proper footwear and prepare for wet or sunny conditions depending on the season.

The ice pits at the foot of the western and northwestern slopes hold heavy cold air that cannot escape from the sealed, trough-shaped lower part of the scree, so ice and snow persist into late spring and early summer. Just below the summit, the Ledová studánka spring keeps a constant water temperature of 5 to 7 °C.
