This is the rival event to the Regata Storica in Venice. Only it takes place on the Brenta River instead of the Grand Canal.
There is a wide variety of activities to enjoy around the Riviera Fiorita:
gondola rides, guided tours of the impressive Brenta villas, bike and boat tours, and - of course, this is a must! - tastings of local products and dishes.
Fun and entertainment are practically guaranteed :)
In any case, it's a vibrant event and - if you're in the area - a wonderful addition to any vacation.
