The farm, with half a mile of estuary foreshore and its own private quay, has been in Charles’s family for yonks. Now it is home to 67 species of bird and a herd of organic cattle. Here, in deepest, wildest, most beautiful Cornwall, are four outbuildings set around the ragged edges of the original farmyard. Bens, the ex-herdsman’s cottage, is lifted by a light, airy Scandinavian feel. Outside: a private patio and walled-garden area. The Barn, a single-storey, 70ft-long space is lovely, functional and super comfy with homely bedrooms and a sleeping gallery up in the roof that kids (eights and over) love. You get a cosy wood-burner, a breakfast bar, and French windows opening to the farmyard and sunny garden. The Farmhouse, built 1810, sleeps eight and has a charming country house style; ideal for families/big groups. And the Flower House, where daffodils were bunched for market. Wander downhill to Scotts Quay – dinghies, canoes and windsurfers are provided – or take off for a spot of wild swimming on the farm’s wildlife-rich lake. The delightful Pughs continue to uphold the National Trust covenant that prevents the spoiling of this charmed landscape for ever.
