This route starts at so called „Green cathedral“ in Proložac Donji. After a short ride along the asphalt road, continue along the macadam road and go towards the archaeological site Opačac, the site of the Franciscan monastery from the Middle ages and Gospina church – the church of St. Mary, erected by the Franceschi family in 1719, once the Turks left this area. The route continues towards several mills that date back to the Middle ages, collectively known as Perinuša. Go downstream following the riverbed to get to the Đogića dam in Zmijavci. Get to the other side and then take the asphalt road westwards, back to the Green cathedral.
