The national park extends to cover much of the western part of the southern
highlands, lying to the north of the
Glasgow conurbation. The park authority defines the park as being split into four sections:
Breadalbane, Loch Lomond, The Trossachs, and
Cowal. The park is centred on Loch Lomond, the largest lake in Great Britain by surface area, with a surface area of . It is a popular leisure destination, and is surrounded by hills, including
Ben Lomond on the eastern shore, which is in height, and the most southerly of the Scottish
Munro peaks. A 2005 poll of
Radio Times readers voted Loch Lomond as the sixth greatest natural wonder in Britain. The Trossachs are an area of wooded hills, glens and lochs that lie to the east of Loch Lomond. The name was originally applied only to a small woodland glen that lies at the centre of the area, but is now generally applied to the wider region. They have long been visited by tourists due to the relative proximity of major population centres such as
Glasgow and
Stirling, and the area remains popular with walkers, cyclists and tourists. The wooded hills and lochs of the area may be considered to represent a microcosm of a typical highland landscape, Much of the Trossachs area is protected by various different
conservation designations, including the "Great Trossachs Forest"
national nature reserve. Breadalbane refers to the northern part of the park, including the villages of
Crianlarich and
Tyndrum. The area consists of the steep hills and mountains of the southern highlands, and includes
Ben More, the highest mountain in the national park. The westernmost part of the park comprises the eastern side of the
Cowal peninsula, which is separated from the rest of the park by
Loch Long. The
Arrochar Alps, a popular location for hillwalking and climbing, lie at the northern edge of Cowal, overlooking Loch Lomond. Several major transport routes pass through the park, including the
A82 road between
Glasgow and
Fort William, which follows the western shore of Loch Lomond, continuing north via
Strath Fillan to bypass the village of
Crianlarich and pass through
Tyndrum. The
A85 road from
Edinburgh passes to the east of the Trossachs and through the Breadalbane area of the park, meeting the A82 at Crianlarich. The only railway in the national park is the
West Highland Line, which follows the eastern shore of Loch Long as far as
Arrochar, and thence runs close to the A82 as far as Tyndrum. ==Formation of the national park==
