My first visit to Polperro a couple of weeks ago reminded me just how clear the Cornish sea can be – where I live on the Devon-Dorset border, coastal erosion means that the sea is often cloudy with sediment.
Most of the time I was there, the clouds hid the sun, but for just a glorious moment, they parted and the sparkling emerald and sapphire glory of the water was revealed. The brooding skies added their own special element, of course.
