David begins his series exploring the scenic beauty, history, and culture of Scotland with a journey into the Highlands and Islands across Argyll to Glencoe.

Along his way, Hayman visits Easdale Island – once the centre of the Scottish slate industry and now home to the World Stone Skimming Championships – and goes on to the notorious Corryvreckan Whirlpool before reaching Glencoe and a brutal engineering masterpiece of the early 1900s: the Blackwater Dam.
