Highclere Castle tours are a popular day trip from London. You can go as part of a group tour of the castle by bus, in a small-group tour by minivan, or on a private guided tour by luxury vehicle or even black cab. Afternoon tea is offered in the castle's tea rooms in the coach house, though you must book in advance.
Some full-day tours from London incorporate stops at other filming locations of the TV series Downton Abbey, such as the charming Cotswolds village of Bampton, which is used to portray Downton in the show. Other tours include non-Downton destinations such as Oxford, home to the esteemed university.
