Skalní vyhlídka Ponorka, Rock pinnacle and scenic viewpoint in Česká Kamenice, Czech Republic

Skalní vyhlídka Ponorka is a sandstone viewpoint above Česká Kamenice in the Děčín district, formed by three rock towers. Carved steps lead up to them, and railed footbridges link the towers. The highest tower looks out on Jehla, Zámecký vrch with Kamenice Castle, and the town below.

The German name Großer Brandfelsen appears in older records, while the Czech name Ponorka (submarine) is used today. The viewpoint consists of three sandstone towers linked by footbridges and reached by carved steps. Some sources give an elevation of 387 m, but the on-site information board states 425 m above sea level.

The name Ponorka ("Submarine") is said to come from the shape of the three connected towers, which resemble a submarine's hull and conning tower. The German name Großer Brandfelsen is also recorded for the formation. Visitors pass carved steps and railed footbridges linking the towers.

The viewpoint is reached after roughly 1,200 m, beyond the Žába rock; the trail then continues to Tell-Platte and the Holy Trinity rock chapel.
