Oxford Transport Timetables
Getting about in Oxford is best done on foot, by bike, by bus or by taxi. Car parking is notoriously difficult, though possible if you are determined, but a good alternative is to use one of the city's Park and Ride facilities. Buses from these into town (as well as along the other major bus routes) are frequent and run quite late. There isn't really a night bus service, but then Oxford is a lot smaller than London and doesn't really open late enough to merit one. For any late-night needs there are taxis in abundance.
Getting to and from London from Oxford is very easy, as there are direct fast trains very regularly, and two rival direct coach services. To and from anywhere else in the UK when starting at Oxford you will need to proceed via Reading/London (the east, south east and north east), Bristol (Wales), Birmingham (the midlands and north east) or Basingstoke (the south). Links to all the info you'll need are below.
