The springs of the Alento river are in Serramonacesca, by the ancient Benedictine Abbey of Saint Liberatore a Majella. The green area of the sources is in Majella National Park, beside the fauna area of the roe deer.
The river has delved and modelled the rocks on which it flows in a succession of pools and waterfalls, modelling the shady river bed. Moss and ferns cover the riverbanks. The crystal clear waters of Alento are full of trouts.
Two trails start from the cloister of the Abbey, one upriver, the other runs along the river with tourist facilities (picnic areas, benches, etc.). The rocky tombs by the river are worth of remark. They probably date back to VIII, IX centuries.
