Velká Klajdovka, Natural monument in Maloměřice and Brno-Vinohrady, Czech Republic.

Velká Klajdovka is a protected natural site on a hillside in the Maloměřice district featuring diverse vegetation and habitats. The terrain includes open meadows, shrubland, and patches of woodland distributed across the landscape.

Velká Klajdovka was officially declared a protected area in 1987, covering about 10.5 hectares on the southeastern slope of Hády. The southern slope of Hády had been a site of scientific study of thermophilic flora and fauna since the 19th century. In the first half of the 20th century almost the whole area was still open grassland, which later became overgrown with shrubs and trees.

The name Klajdovka refers to the surrounding locality rather than to any hotel; the protected area covers about 10.5 hectares of the southeastern slope of Hády. Since the 19th century, Hády has been a site of scientific study of thermophilic flora and fauna, and entomologists still come to look for species such as the spider Cheiracanthium montanum.

The site is readily accessible by public transportation with bus stops nearby. Visitors can walk through at their own pace and enjoy informal pathways across the hillside.

The rare spider Cheiracanthium montanum lives here, one of the site's notable invertebrates. Badgers have dug several burrows in the clay sediments of the central part, and the smooth snake and green lizard, once thought extinct on Hády, have reappeared in recent years.
