DUKW, widely pronounced ‘duck’, are amphibious trucks that were designed by the American military during World War II to transport equipment and troops over both land and water. Nowadays, you can take a trip in a DUKW in central London, on the aptly named Duck Tours. On a tour you’ll drive past famous London landmarks before dramatically launching into the River Thames to get a view from the water. They’re the only way to experience the sights of central London by land and river – without leaving the comfort of your seat!
