This episode begins at Bibury in the Cotswold Hills at a privately owned stream. Rob and Tom then head north by train to the tiny village of Altnaharra (pop. 35) in the far north of Scotland. Heather-covered hills, unspoilt lochs and some sensational single-malt whiskeys make this a very special trip. There were trout, sea trout and the possibility of a salmon, the most highly sought after fish in Great Britain.
