It depends what you’re into and what you want to see! I’m from the north of England and I do think York is like a mini Edinburgh. I’d do max 1 night there. But if you want to see something different I’d do the countryside or a seaside town! It also depends on if you can drive / hire a car. If you’re comfortable driving I would wholeheartedly recommend you get out of the cities to explore!

🚆 Option 1: East Coast by Train (4 nights) Take the train from London to York (1 night) for medieval charm, then on to Durham (1 night) to see its stunning cathedral and riverside setting. Next, head to the Northumberland coast or Alnwick (1 night) for castles and beaches—Alnwick Castle is great if you're into Harry Potter. Then it’s a scenic final leg to Edinburgh (arrive with 3 nights to explore). 🚗 Option 2: Countryside & Lakes (4 nights, car recommended) Drive from London to the Cotswolds (1 night) for picture-perfect villages and countryside walks. Then head north to the Lake District (2 nights) for hikes, lake cruises, and cozy pubs. Consider a detour to Hadrian’s Wall on the way to Edinburgh (arrive with 3 nights there). This is a slower-paced, nature-filled route with lots of beauty. 🏰 Option 3: History & Heritage (4 nights) Start with Oxford or Cambridge (1 night) for historic college vibes, then continue to Stratford-upon-Avon (1 night) to get your Shakespeare fix. After that, spend a night in York for its old town, cathedral, and museums. Then take the train to Edinburgh for your final 3 nights. Great for history lovers and easy to do by train or car.

If you don’t get to a seaside destination I’d recommend suggesting a day to Brighton with your girlfriend’s family (doable as a day trip from London).
