Every year thousands of hikers and cyclists head out on Spain's Camino de Santiago (also known as the 'Way of St James'), a famous Christian pilgrimage and network of trails leading to the cathedral of Santiago de Compostela in Galicia. Camino Skies focusses on six Kiwi and Aussie hikers all aged between 50 and 80, who team up to tackle the 800 kilometre journey together. They each have personal reasons for taking up the challenge, and as the miles clock up they become pilgrims, battling blisters, grief, and the niggles of age to reach their goals.
