Gnojno is the northernmost place in the Lublin voivodeship. The village is located in a picturesque land, known as the Podlasie Bug Gorge, within the borders of the landscape park of the same name. Hilly mesoregion on the border of two countries and three voivodeships, divided by the Bug river, is famous for its extraordinary silence, pristine nature, and perfect conditions for anglers. Gnojno is also famous for the nearby viewpoint, which presents one of the most beautiful panoramas in the Lublin region. From the top of a dozen meters high slope, washed by the waters of the meandering Bug, one can see a wide river valley, endless meadows and pastures in the vicinity of the village of Niemirów (Podlaskie voivodeship), as well as the Mielnicka Forest on the hills visible on the far horizon.

In Gnojno, there is a historic church of St. Anthony, erected in the years 1880-1883 as the Orthodox Church of St. Paraskieva. The film enthusiasts can recognize the vicinity of Gnojno - it was here that the scenes for the film "Nad Niemnem" were shot, where the wild and unregulated Bug played the role of the title river from Eliza Orzeszkowa's novel.
