My parents in law have a house in riccione, right next door. In fact this is where i’m at now…
The beach is really crowded and not picturesque at all, but it can be fun. It used to be and still is a popular resort, with all the activities that come with it — amusement and water parks, lots of shops, restaurants etc. Riccione nightclubs are famous all around italy if you’re into that kind of thing.
More excitingly, at least if you find a car, a little bit inland you have the colline romagnole, which are beautiful hills full of pretty little towns and great agriturismi with some of the best food in italy. Really nice places to visit include san marino, verruchio, san leo, gradara, urbino… Road riding is also very popular here.
