Krásná Stráň, natural monument in Karlík, Czech Republic

Krásná Stráň is a 20.2-hectare natural monument on a forested southeastern slope between Karlík and Vonoklasy, at 215–347 m. Its bedrock is Ordovician shale and sandstone of the Králův Dvůr and Kosov formations, cut by erosion gullies. The slope carries acidophilous oak and oak-hornbeam woodland, dry rocky oak scrub, and rock grasslands with Festuca pallens and Campanula bononiensis.

Tradition holds that the Knights of the Cross with the Red Star, owners of nearby Dobřichovice, founded a vineyard here under Charles IV; the Hussite Wars halted it. Grand Master Antonín Brus of Mohelnice revived it in the later 16th century with 10,000 vines, cellars and terraces. The Thirty Years' War damaged it, and in 1841 priest Kalaš had it abolished; pines and orchards followed, with only cherries left. It became a natural monument on 16 June 2003.

The name Krásná stráň means "beautiful slope". The slope was once a vineyard: the Knights of the Cross with the Red Star planted vines here, and in the second half of the 16th century Grand Master Antonín Brus of Mohelnice had 10,000 vine seedlings set out and wine cellars and terraces built. Only cherry trees remain of the later orchards.

The monument lies on a wooded southeast slope between Karlík and Vonoklasy, about 500 metres southwest of Vonoklasy. Marked hiking trails reach it from both villages. The slope is cut by erosion gullies and has dry, uneven ground, so wear sturdy shoes and carry water; there are no facilities inside the protected area.

The green lizard population here is one of only two left in the Český kras, and these lizards reach up to 30 cm, making them the largest lizards in Bohemia. The moth Pyrausta castalis also reaches its northernmost known site on this slope.
