A campus walk past the real Harvard and MIT buildings that have played fictional lecture halls and dorms
Film crews come to Cambridge for streets that can pretend to be anywhere. Here is what they used. Five stops over 4.4 miles, about two hours of walking. Every stop narrates itself when you get there, at whatever pace you feel like walking.
It is one of eight tours in Cambridge, each taking a different line through the city. Nothing is booked and nothing expires, so you can start it on a whim and finish it whenever you like.
