We are just 2 weeks away from starting our almost 5 week summer European trip. Our longest stay will be in London. We are looking for some ideas for a day trip, preferably no more than 2 hours reachable by train. My choice would be York but since we've been there a few times before, we're looking at other areas. We've also been to Brighton, Warwick, Oxford, Cambridge, Stratford upon Avon, Canterbury, St. Albans, Cheltenham, Bury St. Edmunds, the Darwin Down House, Cardiff, Bath and Stonehenge for day trips as well as some much longer stays.
Any personal experience or recommendations for an all day trip, by train, to a beautiful or historical significant town or city? We like scenic towns/cities, beautiful architecture, art, science and literature spots. Thanks in advance for brainstorming along with us.
