5. Walking Tours
At the Visitor Information Center on Broad Street, you can sign up for all kinds of guided hikes. The most popular are around the historic colleges at the University of Oxford and they leave every day at 11:00, 13:00 and 14:00. This tour does not run in Christ Church or New College, both of which are included in this list.
Tolkien spent much of his career in Oxford, shooting scenes from the Harry Potter films all over the city The Visitor Information Center organizes theme hikes that point to Tolkien’s former haunt, or take you to New College, some of which were Hogwarts in Harry Potter. Two companies that I recommend for free hikes are Footprints and Strawberry Tours.
