"If you’re exploring Boston for the day, take a walk up through Back Bay from Massachusetts Avenue and loop back down along the Esplanade or head over the Harvard Bridge to Cambridge (Ironically, the Harvard Bridge ends at M.I.T.). It's a narrow paradise along both sides of the Charles River, stretching for several miles between the Longfellow Bridge to the west and the Boston University bridge to the east. More than 1,500 trees line the walkway (or runway, if it's marathon-training season), while playgrounds, ponds, and gardens bring a lyrical quality to this meandering landscape. It's best viewed in autumn, when the Esplanade shows its true colors. The Hatch Shell is a performance space that serves as home base for all things at the Esplanade including the famous performance by the Boston Pops on the Fourth of July." - Paul Rubio, Todd Plummer
