Càrn Mairg Circuit

The most common starting point for the Càrn Mairg Circuit is from Invervar in Glen Lyon. A car park has been built there by the Chesthill estate, though it has limited capacity. It's advisable to arrive early, especially during peak season, to secure a spot.

The terrain is primarily high, rolling moorland. The initial ascent involves a narrow path through woods, then a broad, grassy ridge. Once on the ridge, much of the walking is on firm, good ground. However, the descent from Càrn Mairg Summit can be demanding, with bouldery and rocky sections. Some areas may also be boggy in wet conditions.

This circuit offers extensive panoramic views, especially on a clear day. You'll summit four Munros: Càrn Gorm, Meall Garbh Summit Cairn, Càrn Mairg Summit, and Meall na Aighean Summit. From various points, you can see across Glen Lyon to the Lawers range, Loch Rannoch, the whaleback of Schiehallion, and even the distant Cairngorms.

The Càrn Mairg Circuit is considered a challenging day hike due to its length (over 18 km) and significant ascent (over 1100m) across four Munros. While much of the walking between summits is relatively straightforward on firm ground, the initial climb and the rocky descent from Càrn Mairg require good fitness and effort. It's generally described as a difficult hike.

Dogs are generally welcome on Scottish hills, but it's crucial to keep them under close control, especially due to deer management in the area and the presence of livestock. Always follow the Scottish Outdoor Access Code, which advises keeping dogs on a leash or under very close control around farm animals and wildlife.

The best time to hike the Càrn Mairg Circuit is during the summer months (June to September) when conditions are generally more favorable. Outside of summer, especially in winter, the route becomes significantly more challenging and requires appropriate winter hiking experience, including the use of ice-axes and crampons.

No, there are no permits or entrance fees required to hike the Càrn Mairg Circuit. Access to the Scottish hills is generally free under the Scottish Outdoor Access Code. However, the North Chesthill Estate, through which the route passes, has requested hikers follow a preferred route and consider their deer management practices.

Yes, the Chesthill Estate, which manages land along the route, has requested that the circuit be done clockwise. This helps to minimize disturbance to their deer management activities. Following this recommendation contributes to responsible access.

A dilapidated line of old rusting fence posts runs along much of the ridge between the Munros. This feature can be a significant aid for navigation, especially in poor weather conditions, mist, or snow, helping hikers stay on track across the high moorland.

From the summits, you can expect extensive and satisfying views. You'll see across Glen Lyon to the impressive Lawers range, over Loch Rannoch, and the distinctive whaleback of Schiehallion. On very clear days, you might even spot the snow-covered Cairngorms to the northeast and the Ben Lawers group of hills to the south.
