The excursion by boat on the river Coghinas includes an ascent of about 7 km from the mouth, in an environment of rare beauty, ideal for birdwatching. The guide will accompany participants, including school groups, birdwatchers, photographers and tourists, in the observation of birds and local flora. Migratory birds, like various species of Ardeidae, arrive in spring from Africa to nest. Before the excursion, binoculars and life jackets will be delivered to children, with explanations on the basis of observation. Along the way, the migratory routes, the nesting, the flora, the marsh tortoises, the dragonflies and the human activities will be illustrated
