The excursions by boat, on foot or by bike leave from the Stazione of Pesca Foce to discover an unique and particular ecosystem, the one of the valleys, constituted by water, land and “casoni”. Every element tells the tale of fishing around the traditional “lavoriero”, a fixed trap in the water which permits catching the eels separately from other fish — such as mullet, sea bass, sea bream, flounder, aquadelle- while they migrate to the sea.
