Two wonderful authors, Susan Branch and Susan Allen Toth, have written delightful traveler's memoirs about England.
Susan Branch's A Fine Romance: Falling in love with the English Countryside is beautifully illustrated with her exquisite drawings. It's a diary of her and her husband's 25th anniversary trip across the Atlantic on the Queen Mary 2 and their adventures through Kent, London, the Peak District, the Lake District, the Yorkshire Dales, and the Cotswolds, definitely the most picturesque places in England. The book is wonderful.
Susan Allen Toth's My Love Affair with England is her travel memoir and it was followed by England As You Like It and England for All Seasons, an excellent trio chock full of adventures throughout the English countryside and cities. Although somewhat dated (the three books were published in 1994, 1996, and 1997), they are nevertheless wonderful resources as a quick Internet search would give you the most up to date information on the sites she mentions.
Charming books for anyone interested in actually visiting or just reading about traveling in England.
