At Edinburgh Castle, sit on the Stone of Destiny, the sandstone seat upon which dozens of Scottish monarchs were crowned. Survey the English Lake District, where mountainous peaks give way to expansive lakes and scenery so picturesque it inspired the words of William Wordsworth. Plus, discover the mystery of Stonehenge, where towering prehistoric stones cast shadows on emerald, green fields and sail across Plymouth harbour, with views of the city's royal citadel. Finally, indulge in a feast at a historic mill in the English countryside, enjoying organic seasonal produce freshly picked from the fields just outside.
