Around an hour away up the Spey Valley is the fabulous Ballindalloch Castle. This is a stunning building with equally impressive gardens that has been the home of the MacPherson-Grants family for 23 generations. It is a lived in house and a working estate rather than a museum piece.
Just south east of Inverness there’s the renowned Cawdor Castle (Again well worth a visit though built after Shakespeare wrote it into history in Macbeth!)
Less than 30 minutes south of us you’ll find Blair Castle, another superb building & home to the Earl of Atholl, who, since Queen Victoria stayed there, is the only man in Britain allowed to maintain a private army - the Atholl Highlanders!!
