The Diabelski Kamień (Devil's Stone) is a monumental glacial erratic that serves as a natural monument within the Nadmorski Park Krajobrazowy (Coastal Landscape Park), located in the Puszcza Darżlubska forest near Połchówko in the Krokowa municipality. The boulder, standing 1.8 meters tall with a circumference of 12.5 meters, lies along the popular trail leading to the Mechowo sand caves, close to another stone known as Boża Stopka (God's Footprint). Historically, both stones functioned as boundary markers, separating the estates of wealthy landowners from Połchówko and Czechy.
The legends surrounding the Diabelski Kamień are a fascinating cultural element of the region. It is said that the boulder was carried by a devil who intended to destroy the church in Mechowa, thwarting his dark plans. As the devil hauled the stone from distant Sweden, he grew weary during the journey and decided to take a short rest to repair his damaged boot. When dawn broke and a rooster began to crow nearby, the devil, enraged, began scratching the stone in frustration—leaving visible marks, scratches, and fissures on its surface that can still be admired today. These distinctive features attract tourists and legend enthusiasts alike, highlighting the enduring interest in local myths and folklore. The Diabelski Kamień is not only a remarkable natural feature but also a valuable cultural landmark, bridging the past with the present.
