This port connects the Noguera Ribagorzana river basin with the Sis valley and the Isábena basin, right on the border between Catalonia and Aragon. From Bonansa, the pass is a little over six kilometers long, with a fairly constant average drop of around 7%. Its other slope, the one that follows the Obarra gorge until it crowns the port, is much longer. It is 15 kilometers long, but it is very flat, with percentages around 3%, until it practically reaches the top, where the last two kilometers present considerable unevenness, with ramps of more than 15%.
