The Trossachs ( listen (help·info); Scottish Gaelic, Na Trosaichean) itself is a small woodland glen in the Stirling council area of Scotland. It lies between Ben A'an to the north and Ben Venue to the south, with Loch Katrine to the west and Loch Achray to the east. However, the name is used generally to refer to the wider area of wooded glens and braes with quiet lochs, lying to the east of Ben Lomond. The Lake of Menteith, in the strictest sense Scotland's only natural lake, lies about six miles (10 km) to the south east of the glen, on the edge of the Trossachs area.
The scenic charms of the area came to popularity with Sir Walter Scott's 1810 poem The Lady of the Lake, extending his romantic portrayal of Scotland's past from border ballads to poems of a medieval past rich in chivalry and symbolism. The poem gives a roll call of Trossachs place names, the lady herself being found on Loch Katrine. Scott followed up with his 1817 historical novel Rob Roy romanticising the outlaw cattle thief Raibert Ruadh born by Loch Katrine and buried at nearby Balquhidder.
