Polické stěny, National nature monument in the Broumov Highlands, Czech Republic

Polické stěny is a national nature monument near Hlavňov and Suchý Důl in the Náchod district, declared in 2009 on the gentler slope of the Broumovské stěny ridge. Its block sandstone, laid down as sediment in a shallow Cretaceous sea, has cracked into huge cubes and weathered into rock plateaus, towers, canyons and gorges. Kovářova rokle, about 1 km long, holds the Mariánská cave and the Kovárna cave.

Polické stěny was declared a national nature monument (ev. no. 13181) on 1 October 2009, when its territory was carved out of the Broumovské stěny national nature reserve. The same ridge now carries two protected areas whose shared border runs along the Stěny crest: the gentler slope toward Police nad Metují belongs to Polické stěny, while the steep side above the Broumov basin stayed with Broumovské stěny. The area is managed by the AOPK ČR through the Broumovsko protected landscape area administration.

The reserve lies near Hlavňov and Suchý Důl in the Náchod district and is managed by the AOPK ČR through the Broumovsko Protected Landscape Area administration. The marked trail through Kovářova rokle, a canyon about 1 km long, passes the Mariánská cave and the Kovárna cave. Rock mushrooms called Slavenské hřiby stand above the hamlet of Slavný.

Multiple entry points give access to the reserve with parking areas and information boards at main trailheads throughout the site. Sturdy footwear is recommended as paths traverse uneven terrain with steep sections.

Kovářova Gorge, about 1 km long, holds two accessible pseudokarst caves: Mariánská jeskyně in its lower part and Kovárna, through which the marked trail passes. Five more underground spaces are documented in the reserve. The gorge drains water from the rock plateaus toward the North Sea.
