The western 'arm' of the county is sparsely populated and dominated by Loch Lomond, which it shares with Dunbartonshire, and the Trossachs (now a national park); Ben Lomond is located here and is the highest point in Stirlingshire at 974 m (3,196 ft), and 9th in Scotland. Several islands within Loch Lomond belong to Stirlingshire, the chief of these being Eilean nan Deargannan, Buchinch, Ceardach, Inchcruin, Inchfad, Ellanderroch, Inchcailloch and Clairinsh. On the north-eastern boundary with Perthshire a small portion of Loch Katrine lies within Stirlingshire, and also the smaller Loch Arklet can be found here.
