If you do one thing in Cambridge....make it the Kings College Chapel. But if you do ANOTHER thing in Cambridge, make it a punting tour!
Yes it is awfully touristy but there's a reason for that. It's a great way to see the city and pick up some interesting facts along the way. We particularly enjoyed all the stories of the pranks played by the students over the years (hanging a car off a bridge, for one!).
This is also the best way to see the Bridge of Sighs and Mathematical Bridge.
There are a few companies offering punting tours, Scudamore's being the most famous but also the most expensive. We chose Let's Go Punting because it was half the price, but had equally good reviews.
Our guide (Ben, maybe?) was friendly and funny and most importantly got us back to shore safely!
I would recommend going on a chauffeured tour with these guys rather than trying punting yourself. They make it look easy but it's definitely not.
And I also recommend going in off-season. We came in March and although it was a bit chilly, there were a lot less people on the river which makes for a far more pleasant experience and better photos
