Dore Holm is a small sea-arched islet off the Eshaness coast, its natural rock arch giving it the shape of a horse dipping its head to drink — which is why it’s known locally as the Drinking Horse. You can’t land, but it makes a cracking view from the clifftop path, especially with a swell running through the arch.
