For their sixth day of their royal tour, Kate and Prince William set off on a three hour trek to the beautiful Tiger’s Nest Monastery, near Paro, Bhutan. Treated to spectacular views as they climbed to nearly 10,000 feet above sea level, the Duke and Duchess barely seemed to break a sweat as they took the hike in their stride. With their arms around each other, enjoying the amazing scenery, Kate joked that the exercise was, “a great way to burn off the curry!”
