Just past Bolventor and the Jamaica Inn the A30 plunges downwards to cross the River Fowey at the point at which it changes from its sinuous and sedentary progress through marshland to becoming a fast flowing moorland river and for just a month during the summer the low lying grasslands here are carpeted in a white blanket of cotton grass.

Upstream from here, below the cairned ridge of Brown Willy are a series of deep pools within the river where my children used to swim in the peaty but surprisingly warm water on sticky Summer's Days.
