A wonderful hill that will reward in all weathers - but you do get the best views if the weather is good! Personally I have found the clockwise circuit better, but in either direction care is needed over the Horns.

This is the famous, classic, view of An Teallach as seen from it's summit Bidein a' Ghlas Thuil. This view across to Sgurr Fiona and the Corrag Bhuidhe pinnacles is IMHO sensational in its own right, but this is made even more special by its sudden appearance. When you climb An Teallach from Dundonnel this whole view is hidden right until the very last moment when you reach the stop of the steep bouldery slope very close to the summit. When you finally crest the ridge and this view opens out in front of you it just takes your breath away. Hope you enjoy it.

The Northwest Highlands are renowned for their challenging terrain. Notable challenging passes include Bealach na Bà Pass, which is considered one of the UK’s toughest road climbs. For hikers, summits like Sgùrr Mòr, Beinn Alligin Summit and Summit of Bidein a' Ghlas Thuill, An Teallach offer demanding ascents with significant exposure and scrambling sections, particularly in adverse weather.
While many passes in the Northwest Highlands are challenging, some routes offer more moderate options or sections. For instance, the ascent to Sgùrr Mòr, Beinn Alligin Summit can be approached as an easier Munro climb if done clockwise, avoiding the more exposed scrambling over the Horns of Alligin. Always check route descriptions for difficulty and consider local conditions.
The mountain passes in the Northwest Highlands offer truly spectacular panoramic views. From Sgùrr Mòr, Beinn Alligin Summit, you can see nearby peaks like Liathach and distant An Teallach. The Summit of Bidein a' Ghlas Thuill, An Teallach provides extensive views across the 'Great Wilderness' towards Sgurr Fiona and the Corrag Bhuidhe Pinnacles. Bealach na Bà Pass offers stunning vistas towards the Isle of Skye.
Yes, several mountain passes and summits in the Northwest Highlands can be incorporated into circular routes. For example, Beinn Alligin is often tackled as a circular route, including the imposing scramble across the Horns of Alligin. Similarly, routes around An Teallach can be designed as circular walks, offering varied terrain and views.
The best time to visit the mountain passes in the Northwest Highlands is generally from late spring (May) to early autumn (September). During these months, you'll typically find longer daylight hours, milder temperatures, and more stable weather conditions, which are crucial for safe and enjoyable exploration of these often exposed routes. However, be prepared for changeable weather at any time of year.
Winter hiking in the Northwest Highlands is possible but requires significant experience, proper equipment (ice axe, crampons, navigation skills), and an understanding of avalanche risk. Many challenging passes, like the Horns of Alligin on Beinn Alligin, become serious winter mountaineering ventures. It's advisable to consult local conditions and forecasts before attempting any winter ascents.
Beyond hiking and climbing the passes themselves, the Northwest Highlands offer a wide range of outdoor activities. You can explore extensive running trails, including challenging routes like the Stac Pollaidh Trail. There are also numerous opportunities for cycling and gravel biking, with routes like the 'NC500 Alternative loop from Ullapool' or 'Gravel Track Along the Loch – View of the Scottish Highlands loop from Alness'. For more information on these activities, check out the Running Trails in the Northwest Highlands, Cycling in the Northwest Highlands, and Gravel biking in the Northwest Highlands guides.
When tackling challenging passes like Bealach na Bà Pass, it's crucial to be well-prepared. For cyclists, be aware of the significant ascent and steep gradients, especially just before the switchbacks. Ensure your bike is in good condition and you have appropriate gearing. For all visitors, check weather conditions as views are best in clear weather, and be mindful of other road users on this narrow, winding road. The descent also requires care due to sharp bends.
The mountain passes of the Northwest Highlands are characterized by ancient geological formations, including Torridonian sandstone and Lewisian gneiss. You'll encounter deep glens, rugged coastlines, and isolated peaks. Highlights like Suilven, with its distinctive double-summited, steep-sided form, exemplify the unique natural beauty of the region, often rising dramatically from a landscape of lochs and moorland.
Many of the prominent mountain passes and summits in the Northwest Highlands are challenging and best suited for experienced hikers due to their steepness, exposure, and remote nature. However, families with older, experienced children might enjoy some of the less technical sections or shorter walks in the glens leading to the passes. Always research specific routes and consider the fitness and experience levels of all family members before setting out.
When hiking in the Northwest Highlands, layered clothing is essential due to the unpredictable weather. Always pack waterproof and windproof outer layers, even on sunny days. Sturdy hiking boots with good ankle support are crucial for the rugged terrain. Additionally, bring a hat, gloves, and plenty of warm layers, as temperatures can drop quickly, especially at higher elevations.
While the Northwest Highlands are famous for their iconic peaks, many less-trafficked passes and routes offer a sense of wilderness and discovery. Exploring the more remote areas of the Fisherfield Forest, for instance, can lead to stunning, secluded passes and summits like Slioch Summit, which offers epic views after a long walk-in, away from the busiest trails.
Parking for accessing mountain passes in the Northwest Highlands typically involves designated car parks at the start of popular trailheads or lay-bys along scenic roads. For very remote passes, parking might be limited to small informal spots. Always park responsibly, ensuring you don't block access for local residents or emergency services. Arriving early, especially during peak season, is advisable to secure a spot.
The Northwest Highlands are a remote region, so facilities like pubs, cafes, or shops are generally sparse and located in scattered villages or small towns. While some popular passes might have a small cafe or pub nearby (e.g., Applecross near Bealach na Bà Pass), it's crucial to carry sufficient supplies, including food and water, for your entire trip. Always check opening times in advance, especially outside of peak season.
Hiking times for major mountain passes and summits in the Northwest Highlands vary significantly based on the route's difficulty, length, and your fitness level. A Munro ascent like Slioch Summit can be a long day, often taking 8-10 hours for the round trip due to its remote access and significant elevation gain. Shorter, less technical passes might take 3-5 hours, while multi-peak traverses can extend to 10-12 hours or even require overnight stays. Always plan your route and allow ample time.
