Welcome to Rathlin Island, off the North Coast of County Antrim.
Having once supported a population of some 1,200 people, the inhabitants of Rathlin has dwindled to around 100 people. It could be called the 'the forgotten island'. In this episode, presenter David Erwin is accompanied by Joe Furphy, as they ramble from one end of Rathlin to the other, taking in the habitats, wildlife and people who call it home.
