Loch Achtriochtan

Loch Achtriochtan is a small, shallow loch on the floor of Glen Coe, in the Lochaber district of the Scottish Highlands. It lies east of Glencoe village, close to 56.665° N, 5.033° W, and the River Coe runs through the glen here. The loch is looked after by the National Trust for Scotland, which also manages much of the surrounding land.

What kind of place is it?

Achtriochtan (also written Trychardan) is not a loch for swimming or boating. It is a quiet stretch of shallow water at the bottom of a deep, glacier-carved valley, with steep slopes rising on both sides. What draws people is the setting: boggy margins, rock walls and, on a calm day, mountain reflections on the surface.

There is a historical footnote too. In the 18th century the water spilled over its banks, and people living nearby had to leave. It helps explain why this part of the glen has so few buildings today.

What can you see nearby?

North of the loch rises the Aonach Eagach ridge, one of the best-known and most demanding ridge walks in Scotland. On the south side stand the buttresses known as the Three Sisters, along with the peak of Bidean nam Bian. The view of these mountains from the A82 is among the most photographed in the country.

Stop also at the small waterfalls nearby, including one where water tumbles down into the River Coe. The simplest way to take in the glen is to combine a few short roadside stops with one longer walk.

How do you get there?

The loch sits right beside the A82, the main road between Glasgow and Fort William. From Glencoe village, drive east along the glen. The road is narrow and busy with little verge, so use only the marked lay-bys and car parks. The nearest larger town with full services is Fort William. Buses use the A82, but timetables vary by season, so check before you travel.

When should you go?

Photography is usually best early in the morning or around sunset, when low light rakes across the valley walls and the water is stillest. In summer the glen fills with coaches and cars, especially at the Three Sisters viewpoint. Outside the main season it is far quieter, but the weather changes fast, and winter conditions in the hills call for proper winter kit. If you plan the Aonach Eagach, set aside a full day: walkers' reports speak of roughly six hours on the hill and more than a thousand metres of climbing.

Can you hike here?

Yes, but pick your route with care. You can see the loch itself from the road and short paths. The Aonach Eagach crosses the summits of Meall Dearg and Sgòrr nam Fiannaidh and is meant for experienced walkers, because parts of it are exposed. Less seasoned visitors will find gentler valley paths leading to waterfalls or high corrie lochans.
