The Duke and Duchess of Cambridge on top of the world as they trek in Bhutan on the final day of their visit to the country
It was a three hour walk with steep slopes and thinning air and lots and lots of photographs. William started to sweat but Kate bounded on - and just said that it was a great way to 'burn off the curry'.
And as they walked in the countryside of Bhutan they looked very relaxed and very happy. Their destination was the Taktsang Palphug Monastery, also known as Tiger's Nest, and it is the cradle of Buddhism in Bhutan.
William and Kate said during the walk that it was important to them to learn more about the religion and history of the country they have called home for the past two days.
The Duke and Duchess of Cambridge were given a tour of the monastery by the monks and had a chance to hear more about its past and its role in the present.
The couple chatted happily to reporters who had accompanied them with William telling them he was now one up on his dad who had only made it half way to Tiger's Nest as he suffers from vertigo. And he had a reminder of what being a father is all about himself - asked if they missed their children, they said 'of course' but the look on their faces was all about parents who need to see the little ones.

The evening brought a reception for people in Bhutan who have lived or worked in the UK and British people with strong links to the country they have visited and got to rather like.
And as they got ready to head back to India for the end of their tour, it was all about the look of love, in all its many guises.
