Arkle from Achfary

The hike typically begins from a track leading off the A838 near Achfary. Parking is usually found along the roadside in suitable, safe spots near the start of this track. Always ensure you park responsibly and do not obstruct access.

While dogs are generally permitted in the Scottish Highlands, this is a challenging and remote trail. Due to the pathless sections, steep climbs, and potential for scrambling on the exposed ridge, it may not be suitable for all dogs. Always keep dogs under close control, especially near livestock or wildlife, and adhere to the Scottish Outdoor Access Code.

The best time to hike is generally during the summer months (June to September) when conditions are most favorable. The trail can take 5 to 7 hours in summer. Outside of summer, especially in winter, the trail becomes significantly more challenging, requiring ice-axe, crampons, and the knowledge to use them.

No specific permits or entrance fees are required to hike Arkle or access the North West Sutherland National Scenic Area. However, hikers should always follow the Scottish Outdoor Access Code, which promotes responsible access to land and water. This includes respecting the environment, taking responsibility for your own actions, and considering the interests of others.

The initial section follows a good track, but beyond that, the terrain quickly becomes rough and largely pathless, ascending over heather and stones. The mountain itself is composed of glistening white Cambrian quartzite, leading to steep, stony slopes. The magnificent ridge is rocky, exposed, and sometimes narrow, often requiring some straightforward scrambling. The quartzite can be slippery when wet.

Hikers are treated to magnificent mountain scenery throughout. Key highlights include the Allt Horn Waterfall, the challenging Arkle Ridge, and the Arkle Summit. From the ridge, there are superb panoramic views of Ben Stack, extending to the sea, and vistas of Arkle's neighbor, Foinaven. Below the ridge, you'll see a 'rosary of mountain tarns' dropping towards Rhiconich.

Navigation skills are crucial for this trail, particularly on the pathless sections, the summit plateau, and the ridge. In mist or poor visibility, the route can be very challenging to follow due to the lack of clear paths. Always carry a map, compass, and GPS, and know how to use them.

Arkle is geologically significant, showcasing a dramatic age contrast between its Cambrian quartzite and much older Lewisian gneiss, with the divide clearly visible on the approach. It's part of the Moine Thrust Zone, where massive rock layers have been pushed over each other, resulting in distinct slanted layers of quartzite.

Yes, the hike begins with a good track from the A838. This initial section is relatively easy and could potentially be cycled to quicken your approach to the more challenging mountain ascent. However, beyond this track, the terrain becomes rough and pathless.
