Serrone (1,044 m), are the Antrodoco gorges (a narrow, wild incision in the rock, about 1.5 km long), which are an obligatory point of passage for communications between Rieti and L'Aquila.

For this reason, the state highway 17 and the Terni-L'Aquila railway climb Mount Giano, which can thus reach the Sella di Corno pass from the Velino valley.

[4] The mountain owes some notoriety to the presence, on its western slope, of a pine forest that forms the inscription "DVX" (duce, from the Latin dux, ducis).

It was built in 1939 (during the Fascist period) by Cittaducale's Forest Guard Cadet School, with the contribution of many local youths, through the reforestation of an originally desolate limestone coastline.

Due to new landslides and rock falls, in 1995 the Lazio region (Badaloni junta) approved work to restore the pine forest,[11] financed in 1998 and carried out in the summer of 2004.
