Loch Lomond is a freshwater loch lying on the Highland Boundary Fault, the boundary between the lowlands of Central Scotland and the Highlands. It is 39 kilometres (24 mi) long and between 1.21 kilometres (0.75 mi) and 8 kilometres (5.0 mi) wide. It has an average depth of about 37 metres (121 ft), and a maximum depth of about 190 metres (620 ft). Its surface area measures 71 km2 (27 sq mi), and it has a volume of 2.6 km3 (0.62 cu mi). Of all lakes in Great Britain, it is the largest by surface area, and the second largest (after Loch Ness) by water volume.[1] Within the United Kingdom, it is surpassed only by Lough Neagh and Lower Lough Erne in Northern Ireland.[2]
Traditionally a boundary of Stirlingshire and Dunbartonshire, Loch Lomond is located in the current council areas of Stirling, Argyll and Bute, and West Dunbartonshire, and its southern shores lie approximately 23 kilometres (14 mi) north of Glasgow, the country's largest city.
Loch Lomond is now part of Loch Lomond and the Trossachs National Park. Ben Lomond is on the eastern shore: 974 m (3,195 ft) in height and the most southerly of the Scottish Munro peaks. A 2005 poll of Radio Times readers named Loch Lomond as the 6th greatest natural wonder in Britain.[3]
The main arterial route along the loch is the A82 road which runs the length of its western shore. For a long time this was a notorious bottleneck, with the route clogged with tourists during the summer months. It was upgraded in the 1980s and 1990s, although the stretch north of Tarbet remains unimproved.
