Cambridge is readily accessible by road, rail and bus. However there is very limited parking available in the city, so we would advise delegates not to bring cars wherever possible.
There is a great deal of useful travel information on the Microsoft Cambridge website at http://research.microsoft.com/aboutmsr/visitmsr/cambridge/directions.aspx and on the Christ's College website at http://www.centralbanking.co.uk/conferences/Travel2Cambridge.pdf. Most of the information given applies equally to Peterhouse College.
The information about travel from London Heathrow Airport to Cambridge by coach may be particularly useful for long-distance travellers. Those with a choice of UK airports are advised to travel to Stansted.
