Břestecká skála, Protected sandstone formation in Břestek, Czech Republic.

Břestecká skála is the end of a larger sandstone and conglomerate rock formation known as Komínky, in the Chřiby range at 280–400 m. Its summit ridge splits into three parts: Plotna, Hlavní kámen and Východní věž, with a weathering-formed fissure cave; 30 climbing routes are recorded.

The sandstone and conglomerate rocks of Břestecká skála were formed during the Alpine orogeny, within the Račany Unit of the Magura nappe group, which originated in the Upper Cretaceous. The site was declared a natural monument in 2002. The surrounding Chřiby region shows evidence of Paleolithic hunting, a Neolithic settlement, and Great Moravian finds.

The sandstone massif is used by climbers, with 30 routes documented on its faces. The ridge at the top splits into three parts named Plotna, Hlavní kámen and Východní věž. A pub called "Pod skalou" at the foot has long been a popular starting or finishing point for visits.

The site is reached by a roughly 400-meter walk along the red hiking trail starting from the parking area where the red and green routes meet. The path is straightforward and accessible for visitors of different abilities.

The rock formations are surrounded by native oak-hornbeam forests and Scots pine populations that create a diverse woodland ecosystem. This combination of exposed rock and forest is relatively uncommon in the area.
