I'm thinking of a day trip in early June (probably the 2nd) and I know there are some exam closures of colleges in June. I do plan to visit the Ashmolean and hope to enjoy a riverside picnic--but I hope I wouldn't be completely shut out on colleges? A couple of years ago I ran into the same issues at Cambridge, but some were open to visitors. I have checked some websites (for example Christ Church College) but they were not specific on upcoming closures. Any information or encouragement would be appreciated!
