Yes. Peterborough is only around 64 km (40 miles) from Cambridge, making the two an easy pairing. Many travelers spend the morning in Cambridge's colleges and riverside, then continue on to Peterborough Cathedral and the market square in the afternoon, all in one loop rather than two separate trips.
Peterborough sits around 137 km (85 miles) north of London. Trains typically take around 45-60 minutes on the fastest services, but that assumes a direct route at a fixed schedule. A private transfer takes a bit longer, generally 1.5-2 hours depending on traffic, but takes you door to door and lets you build in a stop along the way rather than being tied to a station timetable.
Most visitors spend around 2-3 hours exploring the cathedral and its close, then another hour or two wandering the historic market square and surrounding streets. That leaves plenty of the day free to add a second stop, like Ferry Meadows or the Nene Valley Railway, without feeling rushed.
Peterborough works well for families thanks to its mix of hands-on attractions. Sacrewell Farm offers rare-breed animals and play areas, the Nene Valley Railway is a hit with kids who love trains, and Ferry Meadows has open space for picnics and cycling. Traveling by private transfer also means no juggling train transfers or timetables with young children in tow.
Peterborough offers more than its cathedral. The Nene Valley Railway is a heritage steam line running through the countryside between Peterborough and Wansford, popular with families and rail enthusiasts alike. History lovers can explore Flag Fen, a Bronze Age archaeological site with preserved timber structures, while Ferry Meadows and the wider Nene Park offer riverside trails and lakes for a break outdoors.
Peterborough's centerpiece is its cathedral, one of England's finest surviving examples of Norman architecture, with a soaring 12th-century nave and a striking painted wooden ceiling. It's also the final resting place of Catherine of Aragon, Henry VIII's first queen, and was briefly the burial site of Mary, Queen of Scots before her son had her remains moved to Westminster Abbey. Few day trips pack this much Tudor and royal history into one stop.
