The Czartowe Pole Reserve was established in 1958. It covers an area of approximately 80.5 ha. The name of the reserve comes from a forest clearing about which it was said that "only devils roamed there." The reserve covers a several-kilometer long section of the picturesque Sopot River valley. In this section there is a whole series of waterfalls, which, combined with a large decline in the bed, makes Sopot resemble a swift mountain stream. The sandy islands that form between the jagged river rapids add even more charm to this unique river. The specific shape of the river bottom and clean water provide excellent living conditions for graylings and brown trouts. A major attraction of the reserve are the ruins of a historic paper mill standing on the outskirts of a clearing that was the property of the Zamość Estate. It was established in the first half of the 18th century and was one of the largest plants in the Kingdom of Poland. Nine types of paper were produced here, including: packaging, printing, office and stamping. During the plant's heyday, the paper produced here accounted for 80% of all paper production in the Lublin Governorate. The paper mill used the power of Sopot's river current, but the proximity of the river also had its disadvantages - the buildings and machines were destroyed by floods several times and required renovation works. Ultimately, a fire in 1883 contributed to the collapse of the paper mill. Reconstruction of the plant turned out to be unprofitable due to the enormous damage. The paper mill fell into ruin, and the local "fiends", suspected of causing the flood and fire, finally had a clearing to themselves. A 1.4 km long nature and educational trail runs through part of the reserve. Along the path, in addition to attractions such as the river gorge, rich vegetation and the ruins of a paper mill, there are also places related to the fight for Poland's independence. You can see an obelisk commemorating the stay of soldiers from the Sanitary Officer Cadet School who stayed here on summer maneuvers in 1931, and a commemorative stone from 1936 placed in the place where the scouts set up their camps. At the partisan cemetery there are symbolic graves of the famous "Mishka Tatar" and "Korsarz", who died defending local residents against repression by the Germans.
