The main towns along the 34.7 km of the Rio Gadèra are Corvara, San Martino in Badia, Longega, and the hamlet of Pieve di Marebbe. The river is mainly named after Lois Craffonara, a linguist and researcher who was a native of Alto Adige, and refers to the Latin word “square”: which is what the Romans called all settlements that were square shaped.
