This year we decided to make our first trip to the States and how could we not start from the route from New York to Washington DC, passing through Philly and Baltimore. We spent a quick day in Baltimore and didn't regret it. Thanks to the guided tour we were able to get a taste of this beautiful city divided into many characteristic neighborhoods, which reflect the nationalities of the European migrants who populated this city after the war. Also nice is the visit to Fort McHenry to observe and take some photos of this sacred place of the Revolutionary War. The guide was very friendly, knowledgeable and helpful.
I think it's an excellent tool for starting the day in Baltimore, then returning to the most interesting places, or getting lost in the National Aquarium.
