The civil parish of Uig extends over a considerable area (roughly ) from the Harris border in the south to Dalmore in the north, and from
Brenish in the west to Lochganvich in the east. The district known locally in Lewis as Uig is also called "West Uig" and is broadly the area west of Little Loch Roag (the narrow inlet extending south from (West) Loch Roag). West Uig contains 20 settlements; Uig parish contains 36 settlements. West Uig was a district of 2,000 people around the 1841 census, but the
Highland Clearances had set in by then and this parish suffered greatly. The villages of Capadale, Pennydonald, Balnicol, Balgreasich and Erista, around where the modern scattered crofting township of Ardroil now stands, were some of the many cleared to make way for sheep farming and country sports. Bhaltos (Valtos) is the largest village in Uig and is home to about 35 people. Since 1999 the land on the Bhaltos peninsula, comprising also the smaller villages of
Cliobh (Cliff),
Cnìp (Kneep), Riof (Reef) and Na h-Ùigean (Uigen), has been owned by the community and managed by the Bhaltos Community Trust. Uig, otherwise known as West Uig, is the largest and most sparsely populated district of the Isle of Lewis. It contains the highest point on Lewis of Mealasbhal ().
Loch Langavat (from the Gaelic/Norse meaning "long lake") to the west covers an area of and is over in length. The coast has significant inlets notably Little Loch Roag, Loch Thamnabhagh, Loch Reasort and
Camas Uig. Camas Ùig contains a vast strand of shell beach which produces a fertile "machair" fringe. Other shell sand beaches and machair are found at Tràigh na Beirigh, Bhaltos, Cliff, Capadale, Mangurstadh and Mealastadh. The Atlantic west coast from Gallan Head to Loch Resort is dominated by cliffs and many small chasms known as "geodhs". Inland the land contains a glaciated profile with thin acidic soil and large rock outcrops of Lewisian gneiss. Of geological note is the discovery of the largest sapphire ever found in the British Isles. The stone discovered in 1995 is on display at the
National Museum of Scotland.
Camas Ùig Uig Beach () is best known as the site where the
Lewis Chessmen () were found. Before 1831, a local crofter discovered a buried hoard of
chess pieces, uncovered by a storm. The chessmen are now in the
Museum of Scotland,
Edinburgh with an overseas exhibit in the
British Museum in London, and replicas in the Uig Heritage Centre in Tuimisgearraidh. They are mostly carved from
walrus tusks, and probably originated in Norway sometime in the 12th century, although when and how they came to be in Uig is unknown. Camas Ùig is surrounded by the villages of Cradhlasta (Crowlista),
Tuimisgearraidh (Timsgarry),
Eadar Dhà Fhadhail (Ardroil) and Càrnais (Carnish). The beach is one of Scotland's leading
kite-buggy locations, being large, flat, and frequently subject to suitable winds. ==History==
