The Saddle is to the side of the head of Glen Sannox and gives fabulous views down the glen, but also up to the neighbouring mountains. Requires care when descending from the Saddle into Glen Sannox.

A fine route, but requires care in places as it is steep and sometimes loose.

This deep notch in the ridge appears to be a fault-line with a deep groove down the mountain side by north and south. The east side is a rock climb, the west side an awkward clamber with exposure. A very atmospheric and airy place!

The Saddle is the Col between Cir Mhor and Goat Fell, and it is also the pass between Glen Rosa and Glen Sannox. The descent into Glen Rosa is straight forward, but climbing down into the head of Glen Sannox requires a good deal of care. The views from the Saddle down either glen are well worth the effort! Please note that the long description above is completely wrong and does not describe the Saddle on Arran, instead it is for somewhere in the Lakes! - I have submitted an error report.

Had to walk up the last part. Bike and gear 30kg with wrong gearing. Nothing to do with my lack of fitness😂

Spectacualr views back down the valley, through the past, to the sea. Be careful which way you take to get here though. Dont go the way I went, unless you're a very confident hike a biker with a light bike (which I'm not, and my bike isn't).

If you’re not confident in the mountains, a walk to this point will give you that big mountain feel without much exposure. If you know what you’re doing, the ridge walks around this point are stunning and fairly technical.

Arran offers several dramatic mountain passes and features. Among the most notable are The Saddle, a significant col connecting Glen Rosa and Glen Sannox, and The Witch's Step on Caisteal Abhail, known for its distinctive notch and challenging climbing opportunities. Another spectacular location is A' Chir Col, though walkers should take the lower path as the ridge is for climbers.
From Arran's mountain passes, you can expect breathtaking panoramic views. For instance, View of Glen Sannox and the Sea from The Saddle offers spectacular vistas down the glen and out to the sea. On clear days from higher peaks like Goatfell, you can see the Firth of Clyde, Jura, Ben Lomond, and even Ireland.
Yes, Arran's mountain passes offer challenging terrain suitable for experienced hikers and climbers. Features like The Witch's Step involve rock climbing and awkward clambering. The ridge walks around The Saddle are described as stunning and fairly technical, while the A' Chir ridge is specifically for climbers.
Arran's mountain passes are characterized by dramatic, glacially-carved landscapes, giving the island a 'Highland feel'. Peaks like Cir Mhor, often called the 'hub of the north Arran hills', have pyramidal shapes due to glacial erosion. The Witch's Step is a deep notch that appears to be a fault-line, adding to the unique geology.
Beyond hiking and climbing the passes themselves, Arran offers a variety of outdoor activities. You can explore numerous mountain biking trails, such as the challenging Glen Rosa to Sannox loop, detailed in the MTB Trails around Arran guide. For runners, there are routes like the Goatfell & Glen Rosa loop from Brodick, found in the Running Trails around Arran guide. Road cyclists can also find routes, including climbs like the one from Lochranza to Sannox, in the Road Cycling Routes around Arran guide.
Yes, some areas offer a 'big mountain feel' without excessive exposure. For instance, a walk to The Saddle can provide this experience. The descent into Glen Rosa from The Saddle is considered straightforward, making it a good option for those who want to enjoy the scenery without highly technical sections.
Descents from Arran's mountain passes can vary in difficulty. While the descent from The Saddle into Glen Rosa is straightforward, climbing down into the head of Glen Sannox from the same point requires a good deal of care. Always be prepared for varied terrain and potential exposure.
The best time to hike Arran's mountain passes is generally during the warmer, drier months from late spring to early autumn (May to September). During this period, you'll encounter more stable weather conditions, longer daylight hours, and less chance of snow or ice on higher elevations. However, weather in the mountains can change rapidly at any time of year, so always be prepared for all conditions.
Preparation for hiking Arran's mountain passes should include appropriate gear for varied weather conditions, sturdy hiking boots, and sufficient food and water. For more challenging routes, navigation skills and experience with scrambling or climbing are essential. Always check the weather forecast before heading out, as conditions can change quickly in the mountains.
When navigating the passes, pay close attention to the terrain. For example, at A' Chir Col, walkers are advised to take the lower, left-hand path to contour below the ridge, as the ridge itself is intended for climbers only. Descending into Glen Sannox from The Saddle also requires careful navigation. Always be aware of your surroundings and choose routes appropriate for your skill level.
