AS part of celebrations to mark the 100th anniversary of the creation of the Picos de Europa National Park in northern Spain, the Spanish Royal family went for a hike in the beautiful surroundings of Enol lake.
The lake is in the Cantabrian mountains of Asturias, a rugged and stunning region that lines the northern coast, close to Santander.
It was also the first official trip that 12-year-old Leonor, Princess of Asturias, was making as heir to the Spanish throne.
She was joined by her parents King Felipe and Queen Letizia, and her 11-year-old younger sister Infanta Sofia.
The Picos de Europa was the first national park in Spain and is known for its rocky trails and dramatic scenery.
The park has a rich wildlife including bears, wolves and deer, and was awarded the UNESCO Biosphere Reserve designation in 2002.
