The terrain is flat and biking is very popular among the locals. Taxis are easily available at the train station. There are rental cars at the small airport just outside town. Parking can be a challenge downtown. There is an extensive local bus line.
The Wikipedia article on Parma gives a good list of the main sights: [].
The Museo Glauco Lombardi  is a particularly interesting and well done museum documenting the life of Maria Luigia, second wife of Napoleon Bonaparte and the Duchess of Parma. The museum is very personal and engaging with many artifacts and belongings of the gifted, talented and well educated Maria. Well worth the visit.
The Piazza Duomo is where you'll find the city's cathedral and the baptistry, both built in the late 12th century. The baptistry was designed by Benedetto Antelami and is constructed from a pink marble called rosso di Verona. The marble appears to change color depending on how the sun hits it. It is one of the most recognized medieval structures in the country. The frescoes inside the building are very moving, as well as the relief sculptures on the interior stone.
Attend the opera at the gorgeous and world famous Teatro Reggio  known for its passionate and critical local opera aficionados. Buy tickets early as the opera is extremely popular in Parma and tickets sell out early. The Festival Verdi celebrates the famous and adored Parma resident Giuseppe Verdi throughout the month of October every year.
Parma Point, Strada Garibaldi 18 Parma,  is a great little shop for souvenirs, postcards and other Parma related memorabilia as well as a nice collection of books of local interest.

A typical restaurant to have dinner is the Trattoria I Corrieri in Via Conservatorio 1, which is situated near the law faculty of the university. Try some torta fritta, and prosciutto di Parma and all the other salami and coppa specialities from that region as a starter, followed by the typical tortelli. If you take Tris di Tortelli, you will enjoy that special type of pasta, one filled zucca (pumpkin), raddichio (red lettuce) and ricotta e spinaci (spinage& cheese).

If you are in Parma, your trip is not complete until you try a hunk of its eponymous cheese, Parmigiano-Reggiano. Known the world over, Parmigiano-Reggiano cheese owes its quality to its source. The cows that produce the milk graze only on grass and hay in fields around the city. The cheese is made and aged from 18 months to over 30.
Another food you must try in Parma is the local cured ham, Prosciutto di Parma. Parma's Prosciutto is the gold standard for salumi. The hams are cured and aged in temperature and humidity controlled rooms for at least 10 months. The result is a salty, sweet, piece of meat that is sliced razor thin and can be eaten all by its self, or as a part of many regional dishes. As far as salumi goes though, Culatello is king. Unfortunately government regulation on the production of Culatello has driven it nearly to extinction, but there are still rogue producers who cure the meat in cellars. Culatello differs from Prosciutto in that it is made from the fillet cut of the ham as opposed to the whole ham. If you can get your hands on some genuine Culatello, do it, because it is next to impossible to find in the U.S. and can go for around $60.00 a pound.
Parma is also known for its delicate stuffed pastas and outdoor markets. Be sure to take advantage of the fresh seasonal vegetables that Parma has to offer.
An aperitivo in Via Farini is something you should not miss. There are several bars in that little street where you will find a lot of people standing outside with a Martini or a Sprizz con Aperol at around 6pm, enjoying the free buffet that is offered, when you buy a drink.
Try a bottle of the local sparkling red wine called Lambrusco; great on its own and perfect with much of the local cuisine. It can be purchased in virtually any bar or corner shop and is very inexpensive.
