Devět skal, Natural monument in Moravské Křižánky, Czech Republic.

Devět skal is a labyrinth of gneiss rock on the 836 m summit of the Žďárské vrchy, formed by three long ridges holding nine towers and three small turrets. The main block carries a railed lookout; east of it runs the main ridge with the Královský zámek, Žďárská and Záludná towers. Walls measure 5 to 19 m, and the fractured blocks rise in angular steps above low undergrowth.

Devět skal has been a protected natural monument since 1976, when the gneiss rock group around the 836 m summit was placed under protection. The monument covers 3.33 ha, and with the surrounding reserve 37.02 ha; it is administered by the Žďárské vrchy Protected Landscape Area authority.

The towers carry their own names: Záludná věž (12 m), Žďárská věž, Královský zámek, Dvojitá věž, Pyramida, Malá věž, and on the Křižánecký ridge Trůn and Milenci. Climbing is limited to the northern walls of the main ridge and the southern wall of Trůn, where about 110 marked routes run on walls 5 to 19 m high.

Visitors should bring sturdy footwear and suitable clothing for changing elevations, as conditions vary by season. The marked paths are accessible, but it's important to respect your own limits and exercise caution during poor weather.

Climbing is restricted to the northern walls of the main ridge and the southern wall of Trůn, where about 110 marked routes run up walls 5 to 19 m high. The protected area covers 3.33 ha, or 37.02 ha with the surrounding reserve.
