The source of the River Avon is conventionally said to be Loch A'an situated between the mountains of
Cairn Gorm and
Ben Macdui. The headwaters of the strath are however the burns that tumble down from the summits of these two hills and from the
Càrn Etchachan into Loch A'an. The river thus begins its journey in the heart of the
Cairngorm Mountains which are never wholly free from snow; the forests cannot extend themslves to a great height on their sides nor a tree rear its head within the region of the cold; even pasturage itself fails, and their rocky summits are covered with a downy coat of yellow sapless moss.
Lochan Buidhe is a small freshwater
loch on the high plateau above Loch A'an situated at over above sea level that is the highest named body of water in the
British Isles. The is a burn that flows from the lochan down the steep slopes near Hell's Lum Crag and into Loch A'an. The
Feith Buidhe disaster occurred near the burn in November 1971. Six individuals, including five fifteen-year-old
Edinburgh school students died of exposure when their group became stranded in the open for two nights in a blizzard. The tragedy is regarded as Britain's worst
mountaineering accident. On the lower slopes of Càrn Etchachan near the rivulet of Garbh Uisge Mhor a titanic block of granite called the Shelter Stone rests on some smaller boulders. There is a cramped space under the stone that can provide some respite from the elements. In the 1830s, the stone was described as being capable of containing 12 or 15 men.
Loch A'an in springtime before the thaw The loch is situated at an altitude of above sea level, has a mean depth of and extends to . Nonetheless, in September 1861
Queen Victoria and
Prince Albert visited Loch A'an on an outing from
Balmoral Castle. Just below the fords the river is joined by the small watercourse of Allt an t-Seallaidh that runs down from the
Lairig an Laoigh pass. About from the fords is the next building in the glen - the Faindouran Lodge
bothy. The river is joined by numerous small tributaries as it wends its way eastwards through the
Forest of Glenavon to the north of
Beinn a' Bhùird and Ben Avon. The most notable of these watercourses to join the river are the Burn of Loin and the Builg Burn originating at
Loch Builg. The latter flows down Glen Builg to enter the Avon on its right bank just downstream of the Linn of Avon falls. The area is devoid of permanent habitation and the first stand of trees is encountered at Inchrory, a shooting lodge some west of the fords. The lodge is part of the Glenavon estate owned by a reclusive Malaysian businessman. Here the river turns sharply northwards. This change of direction is due to the ice-age glaciers cutting through the pre-glacial watershed causing the headwaters of the Avon to be diverted - a process of
river capture that resulted in the upper Avon flowing into the Spey rather than due east into Strathdon. The narrow glen becomes wooded after about and here the river is joined by the Muckle Fergie Burn from the east. A kilometre later it reaches the farm of Birchfield and at this point the valley widens and becomes the
strath proper.
The main strath The farm of Delnabo sits on the west bank of the river at its confluence with the Water of Ailnack, which enters the strath from the confines of a precipitous gorge - the higher reaches of this watercourse are known as the Water of Caiplich. The farm is overlooked by the Queens Cairn viewpoint and is served by a metalled road which crosses the river and continues in a northeasterly direction to the village of
Tomintoul, the largest settlement in the strath. Located in the parish of
Kirmichael, the village's population was 322 at the time of the
2001 census. At it is the highest village in the Highlands. The A939 crosses the river at the old Bridge of Avon and a surfaced road, the B9136, follows the river's course downstream. The strath is much more thickly wooded from this point on. The Conglass Water originating at the
Lecht, enters the Avon from the east and the Burn of Lochy enters from Glen Lochy to the west. Above Bridge of Brown the Lochy is fed in turn by the Burn of Brown.
Tomintoul distillery, founded in 1964 and which produces
malt whisky bottled as a
single malt, is located in this part of the strath. The lowermost tributary of the Avon is the River Livet which enters from
Glenlivet on the right bank at Drumin just as the Avon leaves the national park. The ruins of the fourteenth century Drumin Castle overlook the confluence of the two rivers. The river and the B road run parallel to one another as they approach Bridge of Avon on the A95 trunk road and the settlement of Ballindalloch under the heights of
Ben Rinnes.
Ballindalloch Castle is a significant visitor attraction, and there are three distilleries in the area –
Cragganmore,
Tormore, and
Ballindalloch, the last of which operates from the castle's estate farm. The River Aa'n reaches journey's end here as it joins the River Spey in the castle grounds. == Cartography==
