The Horns of Alligin: a Step-by-Step Scramble Guide

The Horns of Alligin, or Na Rathanan, are a striking trio of rocky pinnacles that define the northeast ridge of Beinn Alligin in Torridon, Scotland. This route combines stunning views of the surrounding peaks with an exhilarating Grade 1/2 scramble over Torridonian sandstone. The Horns of Alligin scramble is a perfect challenge for experienced hillwalkers seeking hands-on adventure amidst some of Scotland's most dramatic landscapes. Though the scrambling is non-technical, the exposure and steep sections demand confidence, agility, and a clear head for heights. This guide takes you through the route step by step, ensuring you are well-prepared for one of the most rewarding ridge traverses in the Highlands.

Route Overview

The Horns of Alligin form part of the full Beinn Alligin traverse, a circular walk of approximately 10-11km with around 1,000-1,200m of ascent, taking 7-8 hours in total. The scrambling section over the Horns themselves typically takes 1-2 hours. This ridge walk offers breathtaking views of nearby Torridon peaks, including the mighty Liathach and the rugged Beinn Eighe.

Starting from the Coire Mhic Nobuil car park, the route ascends steadily through the glen, crossing rivers, grassy slopes, and rocky bands before reaching the northeast ridge of Beinn Alligin. From there, the scrambling begins. The sandstone rock is generally sound, but care is needed on steep descents, particularly on the first Horn. For those who wish to avoid the crest, bypass paths are available, but they are narrow, exposed, and often slippery, so they are not necessarily easier or safer. The ridge culminates in a steep but straightforward descent back to the glen, completing the loop.

The Walk

Below is a stage-by-stage breakdown of the route to help you navigate this iconic scramble.

Stage 1: Coire Mhic Nobuil to the Northeast Ridge

The walk begins at the Coire Mhic Nobuil car park (grid ref. NG 88161 58893), located just off the A896. Cross the bridge over the Abhainn Coire Mhic Nobuil and follow the well-maintained path upstream along the Allt a' Bhealaich. The route is pleasant and scenic, with opportunities to refill water supplies at the rivers early on. After approximately 2km, look out for a cairn at NG 88242 60149 where the path forks. Take the left-hand fork, which begins to climb steeply towards the ridge.

The ascent is marked by rocky bands interspersed with grassy terraces. The sandstone here provides excellent grip, but the terrain becomes increasingly technical as you approach the col northeast of Sgùrr Mhòr (grid ref. NG 87135 61304). This is a good spot to take a break before tackling the Horns, as the scrambling section is both physically and mentally demanding.

Stage 2: Scrambling the Horns

This is the highlight of the day: a knife-edge ridge punctuated by three rocky pinnacles. The scrambling begins easily, with straightforward Grade 1 moves over solid rock. However, the exposure increases as you progress, particularly on the first Horn (An t-Sail Bheg), which requires a steep descent on its far side. This descent can be tackled via a short chimney or by traversing ledges to the side. Both options demand careful foot and hand placement.

The second and third Horns are slightly less challenging but remain highly exposed, with airy drops on either side. The rock here continues to provide excellent grip in dry conditions, but take extra care if the sandstone is wet or greasy. For those who may feel overwhelmed by the exposure, bypass paths are available on the south side of the ridge. These tracks, however, are narrow and can be more intimidating than the crest itself due to their steepness and lack of handholds. Reaching the end of the Horns provides a tremendous sense of accomplishment, along with unbeatable views back towards Sgùrr Mhòr and across Torridon.

Stage 3: Descent to Coire Mhic Nobuil

After completing the Horns, follow the ridge as it descends towards the glen. The path is clear and marked with cairns, leading over a mixture of grass and rocky bluffs. While the scrambling is over, the descent is still steep in places, so take your time to avoid slips. The path eventually rejoins the glen near the starting point, completing the circuit. Celebrate with a well-earned rest and soak in the views of the route you’ve just conquered.

Getting There and Parking

The Coire Mhic Nobuil car park is situated along the A896, about 6km west of Torridon village. It is a well-maintained parking area with room for several cars, but it can fill up quickly during peak season. Arrive early to secure a spot, particularly on weekends or during good weather. There are no facilities at the car park, so plan accordingly. The nearest public transport options are in Torridon village, but having your own vehicle is the most convenient way to access the trailhead.
