It can be hard to catch a cab on the street in Baltimore. The best places to flag one down are at Pratt and Light streets in the Inner Harbor, Cross and South Charles streets in Federal Hill, O'Donnell Square in Canton, and at Broadway and Thames Street in Fells Point. Otherwise, your best option is to phone ahead and ask for a pickup, or ask your hotel concierge or doorman to summon one for you. Meters determine local fares, which average $7–$15, depending on how far you go.
Baltimore Water Taxi is a fun and convenient way to get around the Inner Harbor. The vessels make stops at 14 points along the waterfront, including Fells Point, the National Aquarium, museums, restaurants, and Fort McHenry. All-day tickets for both services are $12 for adults and $6 for children 10 and under. Look for stops, marked with signs, all along the waterfront; depending on the season, boats arrive every 10–15 minutes, or you can call to be picked up at a particular location.
