Hikes around Loch Stack explore a landscape in the North West Highlands defined by rocky hillocks and numerous small lochs, a terrain known as "knock and lochan." The area is framed by the steep slopes of prominent mountains, including Ben Stack and Arkle, which are composed of distinctive Cambrian quartzite. The ground on many routes can be boggy and pathless in sections, requiring good navigation.

Popular around Loch Stack
The summit of Arkle is a big stone covered dome, easy to climb onto after the narrow ridge, and the views are more restricted than on the ridge itself, but still worthwhile.

The narrow ridge is an 'interesting' section - fine in good dry weather but caution is required in wet / windy weather. Quartzite becomes as slippery as soap when wet, and the narrowest part of the ridge is flat slabs of the stuff.

True Scottish wilderness. The Bealach Horn is worth all the effort of getting there. Magestic Sutherland lies in front. The views on a clear day are incredible. The descent to Achfary from here on a bike is amazing!

The ridge approaching Arkle is a pathless spine of quartzite. The ridge is rocky, exposed and has a little easy scrambling. In wet weather the rock can be a bit slippery.

Arkle stands at 787 m in the North-west Sutherland region of the highlands. It's a large, curving ridge of shattered quartzite with great views over the area and back towards Foinavon.

Meall Horn at 777 m is a complex mountain in the heart of Sutherland. The views from the summit to nearby Arkle and Foinaven are worth the walk.

Yes, there are circular routes available. For a challenging day out that includes a summit, the Ben Stack from Loch Stack loop is a great option. It’s a 7.5-mile (12 km) trail that takes you through the rugged terrain surrounding the loch. Be prepared for some pathless and boggy sections.
The terrain around Loch Stack is classic of the North West Highlands. Expect a mix of conditions, often within the same hike. Lower-level paths can be very boggy and require crossing streams, while ascents of mountains like Ben Stack and Arkle involve steep, rocky sections. Good navigation skills are essential as many parts of the routes are pathless.
While the region is known for its challenging peaks, there are a couple of easier options. These routes tend to be shorter and avoid major ascents, but they can still involve boggy ground. For a less strenuous experience, consider exploring the lower-level paths along the glens, which still offer a powerful sense of the wild landscape.
Yes, dogs are generally welcome on the trails, but the area is home to livestock and sensitive wildlife like ground-nesting birds. It is crucial to keep your dog under close control at all times, and on a lead where necessary, especially during lambing season (spring) and the deer stalking season (late summer to autumn).
Arkle is a significantly more demanding hike than Ben Stack. The route to Arkle's two summits is longer, involves more ascent, and includes a ridge walk with some light scrambling. The Arkle from Achfary trail is rated as difficult. In contrast, Ben Stack is often called a 'perfect mountain in miniature'—it's a shorter, though still steep, moderate hike.
A bothy is a simple, unlocked shelter, free for anyone to use. They are a common feature in the Scottish Highlands, offering refuge for hikers. There is a well-known bothy on the shores of Loch Stack, which was historically used by the local crofting community. It provides a welcome haven from the elements and fantastic views.
In line with the Scottish Outdoor Access Code, wild camping is generally permitted in the Loch Stack area. It's a superb location for it, thanks to the remote and wild landscape. When camping, be sure to follow the 'leave no trace' principles: camp away from roads and buildings, be considerate of wildlife, and take all your litter with you.
Parking is limited and informal. For hikes up Ben Stack, there are small lay-bys along the A838 road near the southern end of Loch Stack where the trail begins. For Arkle, parking is usually found near the hamlet of Achfary. Arrive early to secure a spot, especially on weekends, and park considerately without blocking any access.
The remote and unspoiled nature of the area makes it excellent for wildlife spotting. Keep an eye out for red deer on the hillsides, particularly during the autumn rut when you might hear them roaring. Raptors, such as eagles and buzzards, are also frequently seen circling the high peaks.
Yes, if you're interested in the unique geology of the Highlands, the Knockan Crag National Nature Reserve is a worthwhile visit. It features excellent walking trails across a dramatic landscape with indoor exhibits explaining the area's ancient geological history, including the famous Moine Thrust.
The area is highly regarded by the komoot community, with an average rating of 4.9 stars. Hikers frequently praise the profound sense of wilderness, the stunning views from the summits, and the rewarding challenge of the rugged terrain. The unique 'knock and lochan' landscape is a particular highlight.
There are around 10 curated hiking routes available in this guide, showcasing the best of the Loch Stack area. These range from difficult mountain ascents like the Meall Horn loop from Achfary to more moderate hillwalks, offering a variety of challenges for different experience levels.
