Nature and local culture meet, from the Cervia Salt Flats to the Comacchio Lagoon, from the Mesola castle to9 the Classe Pinewoods. For nine weeks, the historic Po Delta, a UNESCO World Heritage Site and haven of green tourism, offers a program of guided tours, theme-based itineraries on earth and water, sports and musical events, exhibitions and tastings. The show is an added reason to roam this large park that straddles the provinces of Ferrera and Ravenna, and discover its treasures . Primavera Slow will kick off in Cervia-Milano Maritima, with excursions and photographic workshops for the City- Nature Special (1 - 11 April) while Comacchiio will host the eagerly awaited Internatioinal Birdwatching and Nature Tourism Fair, from 30 April to 2 May www.podeltbirdfair.it
