Ondřejník, Mountain summit in Moravskoslezský kraj, Czechia

Ondřejník is a massif of the Štramberk Highlands in the Moravian-Silesian Beskids foothills, running about 8 km north-south and under 3 km wide. Its summits are Ondřejník (890 m), an unnamed 903 m point, Stanovec (899 m) and Skalka (964 m), the highest and the only one reached by a marked hiking trail.

The massif's tourist history began in 1906–1907, when the Moravian Ostrava branch of the Czech Tourist Club, founded in 1899, built its first mountain hut in the Carpathians below the Ondřejník summit. The hut was enlarged in 1930, and in 1933 the neighbouring Solárka chalet was added; it burned down in 2002. A chapel of St Anthony of Padua stands nearby.

The massif's name is linked to the outlaw Ondráš (Ondřej Fuciman, born 1680), who according to legend hid his loot underground and dug a passage from Skalka toward Lysá hora, sealing its entrance with the boulders below the summit. A chapel of St. Anthony of Padua stands near the Ondřejník hut, and a pilgrimage is held there each year on the saint's feast day.

Only Skalka (964 m), the highest summit, has a marked hiking trail; its southwest slope holds the Skalka nature reserve with fir-beech stands up to 180 years old. Two cross-country ski routes run along the slopes, and clearings on the steep gradients are used for paragliding. The tourist chalet Ondřejník stands below the Ondřejník summit (890 m) on the southeast side.

The boulders below Skalka's summit inspired a legend that the outlaw Ondráš (Ondřej Fuciman, born 1680) hid his loot underground on Lysá hora, digging a tunnel from Skalka whose entrance he blocked with these very rocks.
