Buckingham Palace, King Charles III's London home, is open for touring (except for the king's private quarters, of course) from July to October. On the tour, you'll have access to the 19 State Rooms where the king and members of the royal family host guests for state, ceremonial and official affairs. Opulently accented with chandeliers, candelabras, paintings by Van Dyck and Canaletto, and exquisite English and French furniture, these rooms display some of the most magnificent pieces from the Royal Collection. Along with the grand interiors, the State Rooms, where kings and queens have entertained guests on both official and ceremonial occasions, are also a witness to history. Those who followed the wedding of Prince William and Kate Middleton closely will recognize the Throne Room, which served as the backdrop for the pair's official wedding photographs.

For tours in the summer, recent travelers suggested taking advantage of the multimedia guide (included with admission and available in multiple languages), so that you hear a detailed history of each room at your own pace. The palace advises you set aside at least two hours to see the State Rooms (and that you wear comfortable shoes), while recent travelers advised that you use the facilities prior to the start of the tour; there are no public restrooms available until you reach the garden. Except in the Garden Café, no food or drinks (except bottled water) are permitted in the palace.
