With some simple tricks, you can visit the historic town of Cambridge and the iconic King’s College on a day trip from London for less than £20 return. This is how we did it.
The train is the best way to get to Cambridge from London. It's fast and the main station is very close to most the main attractions. Since we had a tight budget, we decided to save money by avoiding the trains leaving from King's Cross station and take one of the trains operated by Greater Anglia departing from London Liverpool Street station. These trains are a bit slower (an average of 25 minutes longer) but the savings are considerable. A return ticket will cost you around £14 from London Liverpool Street instead of an average of £35 from King’s Cross station. In order to see as much of Cambridge in half a day, we left London on the 8:28 am train.
What we did in Cambridge:
Once we arrived at Cambridge train station, we followed the signs towards the city centre. After 15 mins of walking, we reached the popular Regent Street which is full of restaurants and shops.
After visiting Regent Street, we visited King's College, dedicated to the King Henry VI. Entry to the college costs £3 per person and includes admission to the Chapel of the King, one of the best examples of English Gothic architecture. Because we visited Cambridge on a weekday, after our visit to King's College we headed over to the Wren Library at Trinity College, an enchanting library open for free to the public only from Monday to Friday from 12:00 to 14:00. Inside we found some rare manuscripts and an early edition of the works from Sir Isaac Newton.
For lunch, we headed to the market square where we tried some tasty food from several of the outdoor stands that offer ready meals and sandwiches for all budgets.
After lunch, we took a walk along the beautiful river Cam and then went on a half-hour trip on one of the traditional punting boats which run throughout the day, even on most weekdays depending on the season and weather.
Cambridge wasn't too busy visiting on a weekday, however if you are in Cambridge on the weekend, there would most likely be a lot more tourists around. Cambridge is definitely a great destination to get out of London for the day, and if you've got time, take the train from London Liverpool Street to save some money.
