Czeskie Kamienie, Summit and scenic viewpoint in Lower Silesian Voivodeship, Poland.

Mannsteine (Czeskie Kamienie) is a granite summit on the Czech-Polish border at 1416 m, about 6 km north of Špindlerův Mlýn. Its summit rocks are blocks roughly 11 m high set along about 50 m of ridge, with boulder and scree fields around them.

The summit rocks are made of Karkonosze granite, with blocks about 11 m high set along roughly 50 m. A date, 14 January 1929, is carved on a boulder near the top in memory of the Czech journalist Rudolf Kalman, who died there in a snowstorm.

The Czech name Mužské kameny ("Men's Stones") pairs with Dívčí kameny ("Girls' Stones"), a granite group 750 m east and two metres lower. The Polish name Czeskie Kamienie ("Czech Stones") and German Mannsteine refer to the same summit on the Czech-Polish border.

The summit lies on the red-marked Main Sudetes Trail between Szklarska Poręba and Karpacz, directly on the Czech-Polish border. A yellow trail from Špindlerův Mlýn reaches Petrová bouda after 8 km and joins the ridge route. The rocks stand in zone I of KRNAP, so stay on the marked path.

On one of the boulders near the summit, the date 14 January 1929 is carved in memory of the Czech journalist Richard Kalman, who died here in a snowstorm; a monument to him stands in the saddle by Śmielec, about 500 m west of the top.
