Borecké skály, Natural monument in Liberec Region, Czech Republic

Borecké skály is a natural monument of 29.64 hectares, declared in 1985, made up of a small sandstone rock town around the 360-metre Bor hill. Unlike nearby rock towns, it has almost no towers: the compact blocks are marked by honeycomb weathering, ledges, rock windows and rust-coloured iron incrustations. The southern wall is exposed and visible from afar.

The site received protected status in 1985 when the District National Committee in Semily designated it as a natural monument. This recognition safeguarded the geological formations for future generations and acknowledged their importance to the region.

The rocks take their name from the hamlet of Borek pod Troskami. A blue-marked trail runs through the site toward the ruins of Trosky Castle, and the sandstone outcrops serve as nesting grounds for kestrels and black redstarts, with ravens first nesting here in the 1980s.

A marked blue hiking trail guides visitors through the rock formations and connects to nearby Trosky Castle ruins, making navigation straightforward. The terrain is uneven with natural obstacles, so sturdy footwear and patience for exploration are recommended.

Ludmilina jeskyně, a pseudokarst cave in the sandstone, has yielded Mesolithic archaeological finds. The rocks also hold honeycomb weathering pits, ledges, rock windows and rock "clocks", and rust-coloured iron incrustations called železivce. Ravens nested here in the 1980s, among the first sites in the region.
