Stob Coire Gaibhre, Stob Coire na Ceannain, Stob Choire Claurigh and Caisteal Loop

This is a big, serious Grey Corries mountain round that links four tops on a long high ridge: Stob Coire Gaibhre, Stob Coire na Ceannain, Stob Choire Claurigh, and Caisteal. Expect roughly 20 km / 12.4 miles overall, though similar versions of the round are often measured a little longer depending on the exact start point and line taken on the ridge. Total ascent is about 1,300 m / 4,265 ft, and it feels every bit of that on the ground because the climbing is sustained, the terrain is rough, and the day is exposed from the moment you leave the glen for the upper slopes. The setting is the eastern end of the Grey Corries above the Lairig Leacach, near Spean Bridge in Lochaber, with the usual vehicle approach coming from the Corriechoille track junction beyond Spean Bridge.

The usual start is best described as the parking area by the track junction at grid reference NN252793, on the rough estate track beyond Corriechoille, south of Spean Bridge. That places the hike head near Corriechoille, Spean Bridge, Highland, Scotland, on the approach to the Lairig Leacach pass. The track is rough enough that careful driving is needed, and some walkers choose to park lower down and add extra distance rather than take a low-clearance car farther in. (walkhighlands.co.uk)

Getting there by car is straightforward in principle: reach Spean Bridge on the A82, then follow the minor road on the south side of the River Spean toward Corriechoille and continue to the rough track approach. By public transport, the practical hub is Spean Bridge, which has both rail and bus links; from there, there is no regular public transport to the actual start, so you should expect to arrange a taxi, cycle the approach, or walk in from the village and add several kilometres each way.

The day begins on estate track through the glen, which can feel deceptively gentle. This lower section is useful for settling into pace before the hard work starts, but it also adds time, so an early start is wise. One notable landmark on the approach is the “Wee Minister,” a wooden replacement for an older stone figure looking back down the glen. The broad surroundings here already hint at the scale of the day, with the Grey Corries rising in a long pale wall above the pass. (walkhighlands.co.uk)

Climb to the ridge

Once you leave the easier approach and begin climbing toward Stob Coire Gaibhre, the character changes quickly. The ascent is long, steep, and unrelenting, usually on wet grass, rough ground, and increasingly stony slopes. This first major climb is where many parties either make or lose time. In poor visibility it is also the point where accurate line choice matters, because the broad lower slopes can feel featureless before the ridge sharpens. HiiKER is the navigation tool to have loaded in advance, backed up by map, compass, and the skills to use them. (walkhighlands.co.uk)

Stob Coire Gaibhre itself is the lower outlying top at about 958 m / 3,143 ft, but it is far from a minor waypoint in feel. Reaching it gives the first real sense of height and opens up the dramatic architecture of the eastern Grey Corries. From here, the route trends toward Stob Coire na Ceannain, with striking views into Coire na Ceannain and its small
