The Duke and Duchess of Cambridge were photographed taking the five-hour hike to the top of a mountain to a monastery. Once there, they met with monks who took them through the monastery and temple.
The royal couple went casual for the outing with Middleton ditching her signature wedges for knee-high brown boots and paired them with olive green pants, a green vest and a white top. Prince William wore a loose button-up shirt and khaki pants.
Middleton and Prince William have been touring India and Bhutan for the past week, doing everything from trying out archery to donning elegant eveningwear.
"When Catherine and I were married, India was the first place on Catherine's list that she told me that she wanted to visit,” Prince William said early into the tour. "Two children and five years later, we have finally made it."
