Černá hora, Mountain summit in the Jizera Mountains, Czech Republic

Černá hora, known in German as Christiansthaler Schwarzer Berg, is the third-highest mountain in the Czech part of the Jizera Mountains. It forms a double peak with Sněžné věžičky (1,066 m), while the main summit reaches 1,084 m; between the two lies the Vánoční louka peat bog. The summit area has granite rock formations, including Čertův odpočinek.

The mountain's history is recorded in three stone memorials. On the southern slope, near the Kristiánov road, a stone monument called Jäger's Death marks where the sledges overturned on the woodcutter Karl Jäger in January 1927. Near the summit, a granite memorial commemorates Hans Simon, who took his own life there in April 1930 at the age of nineteen.

The mountain's German name, Christiansthaler Schwarzer Berg, refers to the nearby settlement of Kristiánov. A granite monument near the summit commemorates Hans Simon, a nineteen-year-old who died here in April 1930, and the stone marker Jägerova smrt on the southern slope recalls lumberjack Karel Jäger, killed by a sled load of timber in January 1927.

The peak can be reached from multiple starting points with trails of varying difficulty levels. Visitors should prepare for changing weather conditions and bring appropriate hiking gear.

The summit is a double peak: the main top at 1084 m and the lower Sněžné věžičky at 1066 m, about 1 km northeast. Between them lies Vánoční louka, the highest peat bog in the Czech part of the range. A yellow-marked trail crosses the whole summit, partly on a wooden boardwalk.
