Punting is the quintessential Cambridge activity, though it is, in fact, a good deal harder than it looks. First-timers find themselves zigzagging across the water and “punt jams” are very common on the stretch of the River Cam beside The Backs in summer. Punt rental is available at several points, including the boatyard at Mill Lane (beside the Silver Street bridge), at Magdalene Bridge, and at the Garret Hostel Lane bridge at the back of Trinity College. It costs around £16/hr per person (and most places charge a deposit), with up to six people in each punt. Alternatively, you can hire a chauffeured punt from any of the rental places for about £12/hr per person.
