Beinn Narnain and Beinn ime

This is a big, rugged day in the Arrochar Alps, linking two Munros above Loch Long on steep, rocky mountain terrain. Expect around 17 km / 10.5 miles overall, though some published variations come out closer to 19 km / 11.75 miles depending on the exact line taken, with roughly 1,300 metres / 4,265 feet of ascent. The usual start is Succoth Car Park, Arrochar, G83 7AA, beside the head of Loch Long near Arrochar village. (static1.squarespace.com)

The character of the walk is demanding from the outset. Beinn Narnain is the rougher of the two peaks, with very rocky ground and short sections of easy scrambling on some lines, while Beinn Ìme is broader and grassier but still requires a long, sustained climb. This is best suited to hikers comfortable on steep mountain paths, loose stone, boulder fields, and rapid weather changes. In mist, the upper mountain can feel serious and committing, so careful route-finding matters. For navigation, plan and track the route with HiiKER. (walkhighlands.co.uk)

Getting to the start is relatively straightforward for a Highland mountain day. By car, most walkers begin at Succoth Car Park, Arrochar, just off the A83 at the head of Loch Long. By public transport, buses from Glasgow stop in Arrochar, and Arrochar & Tarbet railway station on the West Highland Line is about 1 mile / 1.6 km east of the village; from Arrochar, the start is only a short walk away. Official local visitor information also notes bus access to Succoth. (lochlomond-trossachs.org)

The climb out of Succoth

From Succoth, the route crosses near the A83 and climbs on a well-used path through birch woodland and lower slopes above Loch Long. Early on, the path zigzags uphill and quickly gains height, so the effort starts almost immediately. Within roughly 2 to 3 km / 1.25 to 2 miles, you are already high enough to look back over Loch Long and across to surrounding hills, with the dramatic rock architecture of The Cobbler becoming a constant presence nearby.

As the route leaves the trees, the terrain becomes more open and more obviously mountainous. The path trends above the Allt a’ Bhalachain and heads toward the famous Narnain Boulders, one of the most distinctive landmarks on the approach. These huge scattered blocks give a clear signal that the day is moving from straightforward hill path into rougher, more broken ground. Around this point, many hikers begin to feel the scale of the route ahead. (static1.squarespace.com)

Beinn Narnain

If taking the common circuit that includes Beinn Narnain first, the ascent steepens markedly as the route heads into rough, rocky slopes. This mountain has a more jagged feel than Beinn Ìme, and the upper section can involve hands-on movement depending on the exact line and conditions. The summit of Beinn Narnain stands at about 926 metres / 3,038 feet, and the name is often translated as “hill of notches,” which suits its broken, craggy appearance. (lochlomond-trossachs.org)

The summit area is stony and exposed, with wide views over Loch Long, The Cobbler, Beinn Ìme, and the wider Southern Highlands. On a clear day, the outlook down Loch Long toward the Firth of Clyde is one of the highlights of the walk. In poor visibility, though, the bouldery plateau and multiple worn lines can be confusing, so this is one of the places where accurate navigation becomes especially important. (walkhighlands.co.uk)

Across to Beinn Ìme

From Beinn Narnain, the route drops west-northwest across stony ground toward Bealach a’ Mhaim before turning for Beinn Ìme. Some older or more direct descent lines are eroded, and the better option is generally to stay on the more established path to the bealach. This middle section can feel slower than it looks on the map because of loose rock, uneven footing, and the need to regain height after the first summit. (walkhighlands.co.uk)

From the bealach, Beinn Ìme rises in a long, steady pull. Although it
