Oxford is one of the most beautiful cities in the world and steeped in academia. The buildings and people here have inspired authors such as C.S Lewis, J.R.R. Tolkien and Lewis Carroll to write classic books. And it's not hard to see why this city is so popular. There's the tranquil setting along the River Thames (known in the city as Isis). Where the University's rowing team meet their match each year. Historical pubs, top-class museums and plenty of parks and gardens. Plus, it only takes an hour to get there from London, making Oxford a really good option for a day trip.
