Plot: Julia’s walk offers one of the most outstanding views over Loch Lomond – at 24 miles long, it’s the largest loch in Scotland by surface area. Picking up the West Highland Way, she hugs the bonnie banks through to the little village of Balmaha on the eastern side of the Loch, and takes a quick boat trip to the ancient Lomond isle of Inchcailloch, with magnificent views across the water and out to the surrounding fells
