According to forum posts, trains are a common transportation option from Bologna to nearby cities such as Modena and Parma. Trains are recommended for day trips as they allow travelers to visit city centers efficiently. Local trains are described as quick and affordable.

Some travelers mentioned the possibility of using buses for specific destinations. For instance, the bus line 576 from Bologna can be taken to reach the Lamborghini Factory, which is a popular tourist spot outside the typical city routes.

While train and bus services are frequently used, car travel is discussed as an alternative, especially for reaching less accessible areas or for more flexible travel schedules. However, navigating through cities like Bologna by car can be challenging due to traffic and restricted zones (ZTL).

For those considering renting a car, it's advised to pick up the rental after leaving Bologna to avoid the complexities of city driving and parking. This strategy seems to be preferred for those continuing onwards to other destinations beyond nearby cities.
