Balmoral Estate is within the Cairngorms National Park and is partly within the Deeside and Lochnagar National Scenic Area. The estate contains a wide variety of landscapes, from the Dee river valley to open mountains. There are seven Munros (hills in Scotland over ) within the estate, the highest being Lochnagar at . This mountain was the setting for a children's story, The Old Man of Lochnagar, told originally by Prince Charles to his younger brothers, Andrew and Edward. The story was published in 1980, with royalties accruing to The Prince's Trust.: The estate also incorporates the 7,500-acre Delnadamph Lodge estate, bought by Elizabeth II in 1978.
