Around Castle Loch - Lochmaben
Castle Loch is the largest of the three lochs and also the most shallow. The ruins of Lochmaben Castle are found on promontory at the south end of the loch. This castle is a former stronghold of the Bruce family and is reckoned to be the best example of an Edwardian (Edward 1, the Hammer of the Scots) Peel left in Scotland.
Surrounding the loch is the Castle Loch Nature Reserve which attempts to reconcile the various interests which use the area: Yachting, Coarse Fishing, Wild Fowling, Bird Watching.
