It's more expensive to catch the train between Brighton and Cambridge, but it will get you there in half the time it takes on the coach. As this is a main commuter route, it?s worth avoiding travel before 09:30, as tickets are more expensive and the trains can be packed during rush hour. The National Express coach leaves from the Pool Valley Coach Station, which is off the seafront just west of the pier. The journey takes approximately six hours, including a transfer at Victoria Coach Station, London or at London Heathrow Airport. A single ticket costs about 22.20 GBP, and a return is 35.50 GBP. There are 30 coaches per day; the first one leaves at 01:00, and they run regularly until the last one at 21:55.
After booking online, you will be issued with an e-ticket, which you need to print out and take with you, or an m-ticket, which is sent to your mobile phone. Otherwise you can get at ticket at the bus station. Buses from Brighton to Cambridge can be very crowded at times and there is no guarantee of a place unless you book in advance.

If you are taking the train, you need to catch it from Brighton Rail Station on Trafalgar Street. There are approximately 3 trains per hour to London Victoria station. From there you take the northbound Victoria (light blue) underground line to Kings Cross mainline station, from where you can catch one of the three trains per hour that go to Cambridge. The journey should take a total of 2 ¾ hours, but allow extra time for negotiating the Underground system. Subway trains run every 2-3 minutes but there are often delays. Try to time your journey so you avoid travelling across London in the rush hour - subway trains can be impossible to board, especially if you are travelling with luggage. A single fare for the whole journey should cost around 34 GBP, or you can buy off peak return ticket for 44 GBP.
The UK train ticketing system is notoriously complicated. It is usually cheaper to buy your tickets up to 6pm on the day before you travel than on the day. And fares are more expensive if you travel before 09:30.
On arrival in Cambridge, it is a 15-minute walk to the town centre, or you can catch a taxi outside the station for around 5 GBP. There is also a bus that runs about every 10 minutes.
To walk, exit the station and continue along Station Road, which is directly in front of you. At the T-junction, turn right onto Hills Road, which takes you towards the city centre.
