Cambridge is the fastest of the classic day trips out of London, fifty minutes from King’s Cross on the quick trains, and the one where the thing you came to see is genuinely unlike anything at home. The catch is that a university is not a museum. Colleges keep their own hours, close for exams and events, and the gate that was open last week may have a sign on it today. Plan around that and the day is close to perfect.
The quick answer
- Fast trains from King’s Cross take about 50 minutes. Services from Liverpool Street take around 1 hour 20 and are usually cheaper, so check both.
- The station is a twenty minute walk from the centre, unlike Oxford. Walk it, take the bus, or allow for it in your plan rather than being surprised.
- King’s College Chapel is the one ticket worth buying, at about £13. Check the college website on the morning you travel, because closures are common and unannounced elsewhere.
- Punting is the other thing worth doing, at about £25 a head for a chauffeured trip. Book it at the river rather than from a tout on the street.
Which train, and the walk nobody mentions
Two routes serve Cambridge from London and they are not equal. The fast Great Northern and Thameslink services from King’s Cross take about fifty minutes and run two or three times an hour. The Greater Anglia service from Liverpool Street takes about an hour and twenty because it stops more, and it is often several pounds cheaper. If your day is long, take the fast one out and the slow one back, and spend the difference on lunch.
Advance fares start around £12 each way booked a couple of weeks ahead. An Off Peak Day Return is usually in the £25 to £35 range and lets you come back whenever you like, which suits a city where the pace is set by how long you sit by the river.
Now the part the guidebooks skip. Cambridge station is a twenty minute walk from the historic centre, through an ordinary stretch of town that tells you nothing about where you are going. There is a frequent bus and a taxi rank, and both are fine, but the walk is flat and easy and the city reveals itself properly when you arrive on foot at the market end. Just do not plan as though the station is next to the colleges, because it is not.
King’s College Chapel, and why it is the one ticket
If you do one paid thing in Cambridge, do this. King’s College Chapel took almost a hundred years to build, has the largest fan vaulted ceiling in the world, and contains a Rubens over the altar that would be the main attraction anywhere else. It costs about £13 to go in, takes forty minutes, and it is the building that makes people understand what all the fuss about Cambridge is.
Evensong, on most days during term, is free to attend and is the chapel doing the thing it was built for, with the choir that made it famous. You sit in the stalls, it lasts about forty five minutes, and it is the single best value hour in the city. Check the times before you travel, because they change with the academic calendar and there is no service in parts of the summer.
Other colleges open to visitors for smaller fees, Trinity and St John’s among them, and the pattern of who is open and when is genuinely unpredictable. Treat any college you get into as a bonus rather than a plan.
Tickets and tours worth booking
A guided day in Cambridge
Transport and a guide who can get you into colleges and explain what you are looking at, which matters in a city where half the doors are closed to the public.
Train times and fares to Cambridge
Compare the fast King’s Cross service with the cheaper Liverpool Street one in a single search. The slower route can save a useful amount on the way home.
A private car from your hotel
Priced per car, so it makes sense for a group, and it removes the twenty minute walk between the station and the colleges at both ends of the day.

Punting, done properly
A punt is a flat bottomed boat pushed along with a pole, and the stretch of river behind the old colleges, known as the Backs, is the reason to get in one. From the water you see the colleges the way they were meant to be seen, across their own lawns, and you pass under bridges you cannot otherwise reach.
Two ways to do it. Chauffeured, at about £25 a head, where someone else poles and tells you what you are looking at, which is the right choice for a first visit and for anyone who would rather not fall in. Or self hire, at about £35 an hour for the whole boat, which is cheaper for four people and much funnier for everyone watching from the bank.
Book at the river rather than from the people selling tickets on the street, where prices are higher and the boat you end up in is not always the one you paid for. Mill Lane and the Quayside near Magdalene Bridge are the two main departure points, and either is fine.
A day that fits
| Time | What | Note |
|---|---|---|
| 09:00 | Train from King’s Cross | arrive about 09:50 |
| 10:15 | Walk in, or the bus | twenty minutes to the market |
| 10:45 | King’s College Chapel | quietest before midday |
| 11:45 | Punting on the Backs | an hour on the water |
| 13:00 | Lunch near the market square | the market itself does good cheap food |
| 14:15 | The Fitzwilliam Museum | free, and one of the best collections outside London |
| 15:45 | Walk the Backs on foot | the other half of the same view |
| 17:00 | Evensong, if it is running | free, about 45 minutes |
| 18:30 | Train back | home by 19:30 |
Drop the punt if the weather is poor and keep the Fitzwilliam, which is free, enormous and dry. Drop the Fitzwilliam if the sun is out, because a clear day on the Backs is the thing you will remember.
London 4 Dummies
The bits nobody tells you
- The Backs The stretch of riverbank behind the old colleges, where their lawns run down to the water. The classic Cambridge view, best seen from a punt.
- Punt A flat bottomed boat pushed along with a long pole rather than rowed. Chauffeured punts come with someone to do the work and the talking.
- Evensong A sung evening service, usually about 45 minutes, free to attend and open to anyone. At King’s it is the famous choir doing what the chapel was built for.
- Term and exam term The university calendar, which decides what is open. Exam term runs roughly late April to mid June and closes many colleges to visitors.
- Porters’ lodge The gatehouse at the entrance to every college, staffed by porters. If a college is open to visitors, this is where you pay and where you ask what you may and may not walk on.
The weeks to avoid
Cambridge is a working university and the calendar matters more here than anywhere else in this guide. During exam term, roughly late April to mid June, many colleges close to visitors entirely and the ones that open do so on shorter hours. Nobody advertises this in a way visitors notice, and people arrive to find the gate shut.
Graduation days scatter through the year and close individual colleges at short notice. The week before Christmas brings carol services that fill the chapel. And the last week of June brings May Week, which is in June, because Cambridge, and which means parties, closed courts and a city full of students in evening dress.
The safest windows are February to mid April, and July to September. Check the King’s College website on the morning you travel, whatever the season, because it takes thirty seconds and saves the one part of the day you cannot replace.
Cambridge or Oxford, if you only have one day
People ask this constantly, and there is an honest answer rather than a diplomatic one. Cambridge is the better day trip. It is closer, the train is faster, the colleges sit together in a compact riverside cluster, and the punting is genuinely better because the Backs give you something to look at from the water.
Oxford is the better city to spend two days in. It is bigger, busier, has more museums, a working city around the university rather than a university with a town attached, and a greater number of things to do when the colleges are closed.
For one day out of London with a train to catch home, take Cambridge. If you want both, there are tours that do the pair in a day, though you will get an hour and a half in each, which is enough to say you have been and not enough to see anything properly.
Visiting from abroad? What to know
🇺🇸🇨🇦 From the US and Canada
Fifty minutes by train and about eight hundred years older than anything at home, which is the point. King’s College Chapel is the one thing to book. Remember that colleges are working institutions rather than attractions, so opening is genuinely unpredictable and a closed gate is nobody’s mistake.
🌎 From Latin America
Buy the train ticket online before you travel, when it is cheapest, and take the fast service from King’s Cross. The city centre is small, flat and easy to walk. Punting is the one paid experience worth the money, and a chauffeured boat costs about the same as lunch.
🇦🇺🇳🇿 From Australia and New Zealand
An easy fifty minute run out of London and a good half day even if the weather turns, thanks to the Fitzwilliam Museum being free and very large. Punting is the same idea as a lazy river cruise with more commentary and a higher chance of hitting a bridge if you do it yourself.
🇪🇺 From Europe
The fast trains leave from King’s Cross, next door to St Pancras, so this is the easiest day trip to reach straight off a Eurostar. Check the college calendar before you go, because exam term closes much of what you came to see and it is not signposted anywhere useful.

How long is the train from London to Cambridge?
About 50 minutes on the fast services from King’s Cross, and about 1 hour 20 from Liverpool Street. Both are direct. The Liverpool Street route is usually cheaper, so it is worth checking both before you book.
Is one day enough for Cambridge?
Yes. The colleges, the river and the museums sit within a twenty minute walk of each other, and a day covering King’s College Chapel, a punt, lunch and the Fitzwilliam is a full and unhurried one.
Can you go inside the Cambridge colleges?
Some of them, some of the time. King’s, Trinity and St John’s charge a small entry fee and open to visitors on most days outside exam term, which runs roughly late April to mid June. Opening changes without much notice, so check on the morning you travel.
How much does punting in Cambridge cost?
About £25 a person for a chauffeured trip of forty five minutes to an hour, or around £35 an hour for the whole boat if you pole it yourself. Book at the river rather than from sellers on the street, where prices are higher.
Should I visit Cambridge or Oxford from London?
Cambridge, for a single day. It is closer, the train is faster, the colleges are clustered together by the river and the punting is better. Oxford rewards a longer visit, with more museums and more to do when the colleges are shut.
Is Cambridge walkable from the station?
It is about twenty minutes on flat ground to the market square and the main colleges. There is a frequent bus and a taxi rank if you would rather not walk, but plan for the gap rather than assuming the station sits in the centre.
