The John William Fortescue Cairn above Simonsbath on Exmoor. Magnificent views in all directions. It is possible to just make out the sea to the West (top left corner) and the Bristol Channel top right. This photo is a stitched panorama. Car parking is not provided so visitors will need to stop either half a mile down the hill or 1/4 mile further back up on the top of the ridge.
