Great Britain 3 Day Itinerary
Before you book anything, know this: since 25 February 2026 most visa-exempt visitors, including Americans, Canadians, Australians and the entire EU, must hold a UK Electronic Travel Authorisation before boarding, not on arrival. Skip it and airlines will refuse to let you check in. It costs 20 pounds, is applied for through the official UK ETA app, and clears in minutes for most people, so do it a week ahead, not at the gate.
Day 1: London
Land, drop bags, and go straight for the Tower of London before the tour buses arrive, it’s still the single best way to get the country’s brutal early history in one place, and the Crown Jewels queue moves fastest right at opening. Catch the Changing of the Guard at Buckingham Palace if the schedule lines up, it doesn’t run daily year round so check the official calendar the night before rather than assuming. Spend the afternoon in the British Museum, free entry, and don’t try to see all of it, pick two wings and actually look at them rather than speed walking the whole building.
Skip the London Eye unless you specifically want the photo. It’s expensive for what amounts to 30 minutes in a slow circle, and the view from the Sky Garden at 20 Fenchurch Street is free with a booked slot and arguably better.
For getting around, contactless bank card and Oyster now work identically for fare capping, so there’s no real reason to buy an Oyster card anymore unless you want the physical souvenir. The Zone 1 to 2 daily cap sits around 8.90 pounds and Zone 1 to 6 tops out near 16.30 pounds, so just tap in and out and let the system charge you the cheapest total automatically. London rain is real but overstated as a constant, pack a compact umbrella and don’t bother with a heavy raincoat in summer.
Day 2: pick one university city, not two
A lot of itineraries claim you can do Oxford in the morning and Cambridge in the afternoon. You can’t, not sensibly. There is no direct train between the two, the fastest connection runs about two and a half hours with a change through London, and most journeys take closer to three and three quarter hours. Trying to cram both into a single day means you’ll spend more time on trains than in either city.
Pick Oxford if you want dense, walkable college architecture and easy day-trip logistics from London, about an hour each way on Great Western Railway. Pick Cambridge if you’d rather punt on the River Cam and see a quieter, flatter town, also roughly an hour out via Great Northern or Thameslink depending on the route. Either way, book rail tickets on the National Rail journey planner in advance, walk-up fares on the day can run double the advance price.
My opinion: go with Cambridge if the weather looks decent. Punting on the Cam past the Bridge of Sighs and King’s College Chapel is a genuinely distinctive activity you can’t replicate elsewhere in England, while Oxford’s college quads, lovely as they are, feel more like a very good architecture museum. Both cities offer free entry to most college grounds and chapels, though a few charge a small fee during exam term when they restrict visitor access entirely, so check individual college websites before you go.
Day 3: Bath and Stonehenge
Morning in Bath for the Roman Baths, still functioning on the same natural hot springs the Romans used two thousand years ago, and if you have time, book a session at the rooftop Thermae Bath Spa afterward to actually bathe in the same mineral water rather than just look at Roman plumbing.
Afternoon at Stonehenge, and this is where advance booking stops being optional. English Heritage now sells timed-entry tickets only, adults run about 27 pounds booked online, and online booking closes three hours before your slot, so you cannot simply turn up and buy at the gate expecting a normal experience. Trains run from London to Salisbury with a connecting bus to the site, but if you’re coming from Bath the practical move is a direct coach tour or a hired car, since rail connections between Bath and Stonehenge involve an awkward change and a long bus leg.
Opinion: Stonehenge is worth exactly one hour of your time and not more. The stones are smaller and further from the path than photos suggest, and most visitors are disappointed if they’ve built up expectations. Bath deserves the bulk of your day.
Practical notes for the whole trip
The currency is the British pound, and contactless cards from most countries work everywhere without a foreign transaction fee headache, though check with your own bank first. Tipping around 10 percent in sit-down restaurants is normal but not obligatory the way it is in the US, and it’s rarely expected in pubs. Dial 999 for police, fire or ambulance, or 112 which also works nationwide. Keep a printed or downloaded copy of your ETA confirmation on your phone before you fly, some check-in staff still ask to see it even though it’s linked electronically to your passport.
