Càrn Dearg (Corrour)

The ecology of Càrn Dearg (Corrour) reflects its position in the wet, western Central Highlands. The long approach crosses extensive blanket bog communities dominated by sphagnum mosses, cottongrass, and deer grass, creating the challenging underfoot conditions that characterise this route. Heather moorland covers the better-drained slopes, with ling, bell heather, and cross-leaved heath creating a purple-brown tapestry in late summer.

Higher on Càrn Dearg, you'll encounter montane heath with blaeberry, crowberry, and dwarf willow clinging to the exposed slopes. The wetter western climate supports lusher vegetation than the eastern Cairngorms. Red deer are abundant across this range, often moving in large herds across the moorland. Mountain hares inhabit the higher slopes. Ptarmigan breed on the summit plateau, while golden eagles hunt across the vast territory.

The approach from Corrour crosses prime black-throated diver habitat, with these magnificent birds nesting on remote lochans. Red grouse are common in the heather, and you may spot greenshank on the wet moorland.

Càrn Dearg (Corrour) is among Scotland's most serious Munro expeditions and should only be attempted by very fit, highly experienced hillwalkers. The 26-kilometre distance and potential 11.6-hour duration demand excellent physical conditioning and mental resilience. Navigation skills must be of the highest standard; the featureless terrain, extensive bogs, and lack of paths make map and compass work essential, and GPS is highly recommended as backup.

Carry comprehensive kit including waterproofs, warm layers, first aid supplies, emergency shelter, head torch with spare batteries, and survival bag. Take substantially more food and water than you calculate needing; this is a long day and energy depletion is a serious risk. Mobile phone signal is absent across most of the route. You must plan meticulously around train times, missing your return train could mean a night out in serious conditions.

Weather can deteriorate rapidly, turning this challenging route into a survival situation. Consider the 4/5 bog level carefully; wet conditions make the terrain even more energy-sapping. In winter, this is an extreme mountaineering challenge. If conditions or your progress give any cause for concern, turn back while you still can.
