The Gaelic name is thought to mean 'loch of the leper' or 'loch of the devious one'. Loch Lubhair lies to the east of Crianlarich in the shadow of Ben More. It is about 1.4 miles in length east to west and around 0.3 miles at its widest. The river Dochart flows in from Loch Dochart in the west and exits toward loch tay in the east. There is a legend regarding a castle on the loch, more likely to have been a crannog, but even this has never been located. The loch has brown trout and is a tranquil place perfect for fishing and the surroundings are interesting for hill walking. The river Dochart flows in from Loch Dochart in the west and exits toward loch tay in the east. Loch lubhair receives the outflow from Loch Dochart by a river considerably less than half a mile in length, so that they may almost be regarded as forming one lake. It affords fair trout fishing, and the scenery round about is very beautiful. Loch lubhair is about 11/3 miles in length, with a maximum breadth of about one third of a mile. Its waters cover an area of about 135 acres, or over one fifth of a square mile, and it drains directly an area of about 5 square miles; but, since it receives the outflow from Loch Dochart, its total drainage area is over 44 square miles.
Loch Lubhair is just 3 miles (4.8km) from Crianlarich which has been a major crossroads for north and westbound journeys in Scotland since mediaeval times. In the 1750s, two military roads met in the village; in the 19th century, it became a railway junction on what is now the West Highland Line; in the 20th century it became the meeting point of the major A82 and A85 roads. As such, it is designated a primary destination in Scotland, signposted from as far as Glasgow in the south, Perth in the east, Oban in the west and Fort William in the north.The village lies in the glen of Strath Fillan at the north western extent of the Trossachs, lying in the shadow of several Munro peaks, notably Ben More, but also Stob Binnein and Cruach Ardrain. Thus Crianlarich is very popular with hillwalkers. Also the village lies halfway along the long distance footpath, the West Highland Way. Its location makes Crianlarich a popular stop for tourists and there are a variety of types of overnight accommodation including guesthouses, B&Bs a SYHA Youth Hostel.
