I spent all day walking around Cambridge again. Followed one of the guide book routes - starting at Great St. Mary's where I climbed 123 steps up the tower (scarily narrow) to have a great view across to King's college to the west and market square to the east. Visited the Botanic garden and then walked back via Crusoe's bridge and Coe Fen. After lunch I walked to Jesus lock and then on to Castle mound before heading back to Churchill college. In the evening we walked back into town for dinner.
