Kate Snow reports from Scotland's Balmoral Castle for "Good Morning America."
More than 150 years ago Queen Victoria fell in love with the Scottish highlands, and Balmoral Estate has been a favorite family retreat ever since.
Recently, the castle was a favorite residence of Queen Elizabeth, the Queen Mother.
"She loved the country," said William Shawcross, author of Queen Elizabeth's official royal biography, "The Queen Mother." "She enjoyed walking a lot. She enjoyed fishing, and later in life, she was fishing in waders, right up into her 90s."
