What is the most touristy thing you can do in Cambridge? Yes, it is the Hop-on, Hop-off Bus! Ever since I came to Cambridge I have always wanted to get on this bus, just for the fun of it. If you are a resident in a city you usually never do these obvious touristy things, but I thought I’d give it a go, as sometimes these activities turn out to be quite interesting and you might learn something completely new about the city you live in.
