Take a stroll around Boston's Charles River on the Esplanade - it's our FAVORITE part of this city!!! For a nice 3 mile loop, we recommend starting from the Charles Street entrance, walking to the Harvard Bridge and going across, then looping back along Memorial Drive to finish by going over the Longfellow Bridge (where we got engaged)! Stunning at sunset.
A uniquely Boston walk (and generally less busy), we enjoy the Harbor Walk from near the Battery Wharf Hotel to the Marriott Long Wharf Hotel. While the Charles often feels like the heart of Boston, this walk is a great reminder that we are on the ocean! Easy to add on the North End and/or the Rose Kennedy Greenway as well.
