Baltimore is relatively easy to get around if you're primarily interested in the Inner Harbor area. The Harbor itself is very walkable once you are there. Within a fairly compact area, there are tons of restaurants, shops and boutiques, a science museum and world-class aquarium. And if you want to go further than the Inner Harbor proper, Baltimore features the Water Taxis, a system of little blue and white boats that run on set routes to sites such as Fells Point and Fort McHenry. The Water Taxis are a unique feature of Baltimore and a fun way to see the city from the water. You can obtain information and a map and hotels and at the pick-up point at the Inner Harbor. For adults, you can ride the Water Taxi all day for $8. You can also buy an annual pass for $80 for unlimited rides. Some people use the taxis to commute to work. Baltimore also has other tourist-friendly and fun transportation options, including the Charm City Circulator, a free bus service that connects points north (Penn Station/Mt. Vernon) and south (Federal Hill) and west (B&O Railroad Museum) and east (Harbor East/Little Italy) through the heart of the City. Hansom cabs (horse and buggy) can be found, as can Segway tours. Finally, for the less adventerous (or if you just want a lift from the train station or to the airport) cabs are plentiful and the fares reasonable.
