Radobýl and Litoměřice Wine Trail Radobýl Hill (399 m above sea level) is a natural monument with a north-south profile exposed by mining, with well-developed columnar jointing of basalt rock and columns arranged in various directions. The south and southwest-facing slopes are covered with grassy vegetation typical of rocky steppes, with an abundance of rare and protected plant species such as brown mullein, stemless goat's beard, and white lily. A cross stands on the summit of Radobýl, the eighth since 1622. Grapes have been grown on the slopes of Radobýl since time immemorial. Thanks to this, the Litoměřice Wine Trail now runs along the hillside, informing visitors about wine and winemaking in the Litoměřice region.
