How to go there from London: from Victoria Station, the National Express leaves every hour, the ticket costs about £13 return, depending on the time, it can be cheaper. http://www.nationalexpress.com/home.aspx
What to do there:
- a rowboat cruise for 45 minutes, we paid £13 each (student price) with a student as a guide, there are cheaper tours, just walk along the riverside and you will find several or you can also just rent your own boat £18 (can fit til 5-6 people) but boating can be quite hard.
- walking around the historic city, many colleges to visit
- the art & craft market on weekends
- museums, botanic gardens
