Beinn Ime & Beinn Narnain
‘Butter Mountain’ & ‘Hill of Notches’
At the head of Loch Long, the Arrochar Alps rise high in the Loch Lomond & Trossachs National Park. This compact cluster of rugged peaks has long been a favourite of walkers and climbers, offering variety, drama, and sweeping views within a single day’s outing. The jagged profile of The Cobbler (Ben Arthur) is the most iconic, its rocky summit resembling a craftsman at work and drawing countless visitors to scramble its pinnacle. Beyond it, the high dome of Beinn Ime, the Butter Mountain, stands as the tallest of the group, broad and commanding at over 1000 metres. Beside it lies Beinn Narnain, the Hill of Notches, steep and scarred with crags and gullies, a rugged contrast to Ime’s smoother slopes.
Together, these mountains form a natural amphitheatre above Arrochar, combining rocky drama with grassy ridges and panoramic views across Loch Lomond, the Firth of Clyde, and deep into the Highlands. Whether climbed individually or linked in a longer circuit, the Arrochar Alps embody both accessibility and adventure — a perfect introduction to Munro bagging and a reminder of the wild spirit that begins where the lowlands end.
