Mullach an Rathain (Liathach)

The massive bulk of Liathach and Mullach an Rathain rises through multiple ecological zones, each supporting distinctive wildlife. Red deer graze the glen floor and lower slopes, often seen from the car park. The initial ascent takes you through areas of heather and rough grassland where red grouse live. As you climb toward Mullach an Rathain, vegetation becomes sparse on the rocky terrain, giving way to montane heath communities of moss, lichen, and dwarf shrubs adapted to exposure and thin soils. Golden eagles frequent Torridon's skies, soaring on thermals along the ridges. Ravens perform acrobatics around the crags, their calls echoing off the rock faces. Above 900 metres on Mullach an Rathain, you enter ptarmigan territory, though these well-camouflaged birds are often heard before they're seen. Mountain ringlet butterflies may be spotted in summer. The combination of quartzite and Torridonian sandstone creates unique habitats supporting rare alpine plants. The west coast location brings high rainfall, supporting lush moss growth on lower rocks.

Mullach an Rathain and the Liathach traverse demand the highest level of mountain experience and should only be attempted by confident scramblers. The exposure and technical difficulty mean this is not a hill for those uncomfortable with heights or scrambling on steep rock. Carry rope if you're uncertain about downclimbing sections, though most experienced scramblers complete the route unroped. Navigation on Mullach an Rathain itself is straightforward in clear visibility, but the pinnacles require route-finding skills. Helmet, map, compass, and GPS are essential equipment. Pack full waterproofs though rain makes the rock dangerous. The 5/5 difficulty rating is well-earned, particularly on the Am Fasarinen pinnacles. Consider your escape options before committing to the traverse, as retreat is difficult once on the ridge beyond Mullach an Rathain. Mobile signal is unreliable. Start early and leave detailed plans with someone responsible. The long descent at the eastern end is knee-punishing after a hard day. Only attempt in good conditions with settled weather forecast.
