The Border Meanders of the Oder River are one of the most interesting, protected areas, lying on the banks of the Oder River in the vicinity of Chałupki, at the mouth of the Olza. At this point, the river is unregulated, and its picturesque meanders along with the surrounding meadows and forests form a valuable natural area. The winding riverbed and its immediate surroundings have been reported to the Natura 2000 Network. The local ecological foundation and the local government aim to reconcile the environmental protection and a rational use of the valley.
