Charlestown’s hilly roads, narrow streets and gaslight lamps, make it an enticing neighborhood to visit. Follow the Freedom Trail over the Washington St bridge from the North End or take the scenic water locks to Paul Revere Park. Walk through City Square and stroll down cute Main street, wandering up the windy residential streets to Monument Square, where you can learn about the city’s history along with a great view of Boston at the Bunker Hill Monument. While it’s not a huge area, there are some excellent restaurants. Find your way to the Charlestown Navy Yard, which is a developing area with lots of condos and an additional site for Massachusetts General Hospital research centers. Here you will also find the USS Constitution Museum. After you’re done, hop on an MBTA ferry at the dock on Baxter street and zip on over to Long Wharf and the New England Aquarium.
