Dating back to the mid-1800s, this castle overlooks the peaceful Sound of Mull. Its imposing exterior gives way to a cosier interior; glowing fires, wood panelling, country house decor, a complimentary array of whiskies and just five bedrooms. The incumbent owners (Tom and Marjorie Nelson) live in a private wing within the building. But they’re on hand to meet guests’ needs, including the supply of a hearty daily breakfast taken sociably, at a 16th-century trestle table. It’s a great choice for families seeking a more intimate stay, and pet pooches are most welcome to join too.
