Petrovy kameny is one of the most striking and mysterious summits in the Hrubý Jeseník range — a jagged rock formation jutting above alpine meadows at 1,447 m, clearly visible against the backdrop of Praděd. This is a place where wild nature, ancient legend and one of the most precious nature reserves in the Czech Republic all come together.

The summit itself is a rocky group roughly 45 by 10 metres wide and about 7 metres tall, shaped over millennia by frost weathering into its distinctive 'tooth' silhouette. In summer, high-altitude meadows and dwarf pine thickets surround the rocks; in winter, a blanket of snow transforms the area into a spectacular viewpoint over Praděd, Vysoká hole and the wider Jeseníky ridges. The main ridge here also forms part of the Great European Watershed, dividing the Baltic and Black Sea drainage basins.

• Ovčárna (car park on the Hvězda–Praděd road) — red trail, approximately 15–20 minutes, easy
• Pass U Barborky from Karlova Studánka — red trail, approximately 30–40 minutes, moderate
• From Švýcárna chalet via the Praděd summit — red trail, approximately 60–90 minutes, moderate

• Climbing directly onto the rock formation is prohibited from spring through autumn due to the Praděd National Nature Reserve — warning signs are posted along the red trail and at the summit approach.
• In winter the summit rocks are accessible as a viewpoint.
• The Petrovy kameny nature reserve on the north-eastern slope is fully closed to visitors — no marked trails lead through it.
• Near hotel Ovčárna there is a bus stop with connections to Karlova Studánka and Malá Morávka, and a Mountain Rescue station.
• The Ovčárenská silnice road operates alternating one-way traffic controlled by a barrier and traffic lights.

In medieval times the mountain was named as a site of witches' sabbaths, and in 1682 Emperor Leopold I of Habsburg ordered it to be solemnly consecrated and exorcised. On its north-eastern slope grows the endemic Jeseník bellflower (Campanula gelida), a species unique in Europe that has survived here since the last Ice Age.
