Baltimore is a really interesting place. The Inner Harbor area has the aquarium and some really great restaurants and shops. But, if you want a true "Bal'mer" dining experience, go to a crab house where they serve fresh crabs by the bucket - beers by the bucket, too. The Baltimore Museum of Art is a very nice museum. There are also some beautiful historical mansions out past the suburbs... You'll be pleasantly surprised at all the stuff to do in Baltimore - so take the trip and enjoy.
Inner Harbor...aquarium, science museum, plenty of stores/restaurants, you can rent a paddle boat. Go on the "Water Taxi's" to other parts of the harbor including the area where they shot "Homicide, Life On The Street". Though, once you venture North from the Inner Harbor, you can easily find the "red light" district.What is there to do in Baltimore?
Defiantly go to the National Aquarium it is so amazing and I'm not that into underwater stuff. Also go to O's game at Camden Yards, also Maryland Science center has really cool hands on exhibits and I think recently renovated. The U.S.S Constellation is a historic Warship that offers tours.

Don't stay in the inner harbor, go over to Fells point. That is the early, original part of Balto. Also, go to the old President street railroad station. The first recorded clash of the civil war between Civilians and Federal troops occurred after the troops arrived at the station and were being transported to Camden Station for the trip to Washington, DC. Ft McHenry is the place Francis Scott Key looked toward on the morning of September 14, 1814 to see if it had fallen. Because he saw the flag as evidence the british had not defeated Balto, he wrote the poem that later became our national anthem. The B%26amp;O railroad museum: the first actual train depot/station in the US. It has a great collection of locomotives. What is there to do in Baltimore? enough to fill at least a day.
