The best period for visiting Comacchio runs from April to mid-October. In particular, for those who love the tastes of the sea, the first two weekends of October host a food festival based on the eel, with tastings and shows in the street.
The best views in town are from the Ponte degli Sbirri: on one side the historic Ospedale degli Infermi and on the other the 19th century Palazzo Bellini and the famous Trepponti, the symbol of Comacchio.
From the Loggiato dei Cappuccini, which leads to the church of Santa Maria in Aula Regia, you can access the historic Manifattura dei Marinati, the pickling works, completely restored into full working order; visit the “Sala dei fuochi” with its 12 stoves, where the eels are roasted on spits before being marinated. The graceful 17th century Fish Market attests to more seaborne activity, and it still sells the daily catch.
Important historic buildings also include the ancient Cathedral of San Cassiano, the Loggia del Grano, and the Clock Tower.
For lovers of archaeology, in Antico Ospedale degli Infermi is the new Ancient Delta Museum, which illustrates the centuries-long evolution of the area and of the human settlements typical of the ancient Po Delta and houses the entire cargo of a Roman ship discovered near Comacchio.
In the late afternoon, when the sunset paints extraordinary colours, the nature reserve of the Comacchio lagoons - south of the old town - is a fascinating environment. A trip into history by motorboat allows you to feel the atmosphere of the lagoon with its 'casoni' (fishing huts) and 'tabarre' (stores/workshops), the fishing equipment, and marvellous vegetation. Bird watching is a particularly attractive activity here.
