Luretta valley extends between Trebbia valley to the east and Tidone valley to the west. It begins at the foot of Serenda mountain (759 m), where the two valleys reunite, and spans from a hilly area until Padana plain, to the point where the Luretta stream flows into Tidone river.
Luretta stream is formed by two other streams: Monteventano, which springs at Moiaccio, and San Gabriele, which springs in Groppo. It has a limited flow and during dry summers its water stops flowing.
Luretta is a closed valley, and with a single important road it links to Trebbia valley (SP no. 65 della Caldarola), therefore it is a very quiet area without traffic and an unspoiled natural landscape.
Its territory is rich in castles, like: Agazzano castle (well preserved and open to the public), Bastardina castle, Boffalora castle (not open to the public, but its perimeter can be treaded on an easy trekking path), Lisignano castle (well preserved but closed to the public), Momeliano castle, Rezzanello castle (perfectly preserved building and park, usually hosting events), Montecanino castle (currently in a bad preservation state, only few buildings are private houses), and Pavarano fortress (restored but closed to the public).
Luretta valley is part of the cultural body of the four provinces, characterised by traditions and customs in common, with ancient songs and dances. The Apennine piffero is the most important musical instrument of this area.
The valley is characterised by agricultural activities, cattle and horse breeding, wine and cheese making. There are numerous restaurants and trattorie even in the smallest villages, offering traditional dishes from Piacenza cuisine and local wines.
