Lewis and Harris is the largest island in Scotland and the third largest in the British Isles, after Great Britain and Ireland. Despite the name suggesting two separate landmasses, it is a single island in the Outer Hebrides, lying approximately 24 miles from the Scottish mainland.
The island covers 841 square miles — roughly one per cent the size of Great Britain — and is divided by mountains into two distinct regions. The northern two-thirds is known as Lewis, while the southern third is Harris. Though physically connected, each region maintains its own cultural and linguistic identity, and locals traditionally refer to them as if they were separate islands. This division reflects the geography: the mountainous terrain creates a natural barrier that has historically shaped settlement patterns and community ties. As the anchor of the Outer Hebrides, Lewis and Harris supports landscapes ranging from moorland and peat bog to coastal machair, sustaining both human communities and significant seabird populations along one of Britain’s most exposed Atlantic coastlines.
