Efficient major city. Oxymoron? We think not. Baltimore is not just another pretty skyline. Around here, people get around – on the Charm City Circulator. This completely free bus system shuttles through the heart of the city, with stops every 10-15 minutes at all of the major attractions and areas. Hop on Baltimore’s Circulator from your hotel to the aquarium, then out to lunch and shopping. Bonus points: The Circulator is green (zero emissions 40% of the time!), techie (text alerts keep you updated on the bus schedule) and family-friendly.
