Many tour groups offer a popular Harry Potter Film Locations Tour, including Luxury Vacations UK. On this tour get a quick peak of Oxford's Christ Church College that inspired Hogwart's, and walk through Gloucester Cathedral.
If Harry Potter is not your cup of tea, you can also sign up for a private tour of Oxford, Blenheim Palace and the Cotswolds. Here you learn the significance of the Oxford Colleges, the Divinity School, the Pleasure Gardens and the Cotswolds villages.
Offered by the Institute of Tourist Guiding, this two-hour walking tour takes you through the city's colleges, covered market and can be tailored to your interests. There is a Ghost Walk tour as well as specifically themed tours for fans of Harry Potter, Inspector Morse, J.R. Tolkien and C.S. Lewis.
Up to four people can sign up to take a guided car tour of Oxford with Butler & Prince. Start at University Park and move on to the colleges and village shops.
Take a guided tour of Oxford from above. Instead of riding in a car or bus, have a helicopter pick you up to see a bird's eye view of the city.
