Trebbia river is born on the slopes of Mount Prelà and crosses the provinces of Genoa and Piacenza. It is one of the symbols of the territory of Piacenza, appreciated for the clarity of its waters and frequented in summer by numerous bathers. The river maintains a tortuous path with a series of magnificent gorges; almost at the end of this spectacular stretch before Marsaglia it receives the Aveto, its main tributary.
Under the Brugnello village, the river flows in an alternation of scenic and spectacular gorges and in a great natural beautiful valley, attracting many tourists for its mild climate and water sports enthusiasts such as canoeing, kayaking, rafting and canyoning.
There are various types of vegetation and in the large areas of river bed there are low steppe formations that are home to some types of orchids. Poplars and willows are variously distributed in the bed. In the hilly part there are the oak, chestnut, hornbeam, cherry. In the undergrowth there are butcher's broom, common rowan, hazel, field maple, viburnum, and Scotch broom.
Due to its geographical location the Trebbia river is a transit point for many migratory birds that use the riverbed for food and rest; during migration you can admire the egrets, night heron, etc. About the larger mammals, there are the wild boar, fallow deer, roe deer, as well as the fox, the rare badger, marten, weasel, hare and the dormouse.
In the river you can fish for trout, chub, etc and where the current is less impetuous, barbel abound.

Brugnello is one of the most beautiful place in the Trebbia Valley and it has been recently restored with its stone houses and the Church on a spur of rock, under the which flows the Trebbia river with crystal clear waters, one of the very few rivers still swimming.
Brugnello occupies a prominent position in sporting tourism: since about 10 years in fact it held the march "Brugnello and its paths," a non-competitive event and open to everyone, valid for the national competition Fiasp Winged Foot.

Marsaglia, which belonged to the monastery of Bobbio, in the mid-1700s, as the province of Pavia, was annexed to the Sardinian state, before moving in 1923 under the jurisdiction of the province of Piacenza. In the old part of Marsaglia you can still see the small stone houses with the slate roofs. It is situated on the right bank of the Trebbia river, near the confluence with the Aveto river.
Marsaglia has considerable tourist development also due to the canoe sport: they are in fact organized competitions in which they participate canoeists from all over Europe.
At the beginning of May it is held the Carlin di Maggio or Calendimaggio, a folk festival to celebrate the arrival of spring, a tradition still very much alive today and magic-propitiatory: the "maggerini" go from house to house and in exchange for gifts, traditionally eggs, they sing verses as auspicious for the inhabitants of the houses themselves.

In the beautiful and aristocratic setting of the village it is hosted since 17 years, between July and August, the Bobbio Film Festival. The program includes film screenings, book presentations, courses of films projection and photographic exhibitions.
Also interesting the project Ippovia of the Trebbia valley, horse ride that goes through the remote villages of Carana, Colleri and Dezza, reaching near Passo del Penice then returning to Bobbio.
