Paul Murton visits Gigha and Jura, two islands of the Inner Hebrides which are only a few miles apart but could not be more different. He begins at the Achamore Gardens on Gigha, which were created in the 1930s by the malted-drink millionaire James Horlick. He loved Gigha's mild climate so much that he bought the island and made it his home. Today Gigha is owned by the community, and many of its residents are incomers attracted by the opportunity to begin a new island life on this small and fertile place. Where Gigha is small, lush and verdant, Jura is rugged and awe-inspiring. Despite being one of Scotland's largest islands, just 200 people live there - alongside more than 5,000 deer.
