The scene is entirely black, white, grey and silver. It is cold, unusually dark and a film of ice is forming on the lake. I’m sitting in an unlit wooden sauna, alone, in immense silence. The only noise is the soft ticking of the stove as the heat rises. Across the water are ghostly silver birches and dark pines. Above them, Orion’s Belt shines bright. This vivid experience feels like midwinter in Canada, Finland or anywhere else about 60 degrees north. So it’s bizarre to know I’m a few miles south-west of Great Yarmouth.
Fritton Lake is an anomaly. Like the Broads to the north, this deceptively big, sinuous lake was largely created by medieval peat-digging, but it’s nothing like its Norfolk cousins. Set in a sandy, hilly landscape of heaths and pines, the northernmost outpost of the wildlife-rich strip of sandy heathlands running up the Suffolk coast, the lake is deep and two miles long but so hidden by trees that many people don’t know of its existence.
