Turning through the quaint village of St Kew, I headed along one of the smaller B-roads to the coast. Before long, the single-track road, high hedges on either side, opened up to the blue of the sea. Compared to its neighbours, Port Quin is a hidden gem. The only people here were a small group of kayakers bobbing out on the water. After popping coins in the car park"s honesty box, I headed up the coastal path to walk off some of my lunch, ducking through thickets of blueberries beaded with rain.
