Visas & entry
A local's honest guide to punting in Cambridge recommends going on a weekday if your schedule allows, since the River Cam gets genuinely crowded with punts on summer weekends, making the ride feel more like traffic than a peaceful glide past King's College and the Bridge of Sighs along The Backs. Their practical tips: the standard experience runs about 50 minutes, and booking ahead during peak summer season is worth doing to lock in a preferred time slot rather than hoping to walk up and get one.
