Paul returns to his native Scotland and joins Richard Phelps to fish for wild brown trout and rainbows in the beautiful Glen Devon Valley, between Stirling and Perth, known locally as ‘the secret glen’. Paul and Richard explore the small chain of manmade reservoirs built over half a century ago and which follow the course of the old River Devon and the one time cattle drovers’ trail. Using traditional Scottish fly-fishing tactics in this superb picturesque setting both anglers are more than rewarded with some wonderful sport from both Brown and Rainbow trout.
