Beinn a' Bheithir - Sgorr Dhearg

Beinn a’ Bheithir – Sgorr Dhearg

Sgorr Dhearg is the 1024.2 m (3360 ft) Munro forming the eastern main summit of Beinn a’ Bheithir above Ballachulish. DoBIH 195 records the highest embedded rock at NN0568855838, 3 m north of the remains of the trig-point base. The cairn is no longer present. The Pap of Glencoe is a different mountain and is not an approach to this summit.

Schoolhouse Ridge and both Munros

The Walkhighlands circuit starts and ends at Ballachulish village car park by the Co-op and toilets, NN084584. Its published totals are 15.5 km, 1387 m ascent and 7–9 hours for both Sgorr Dhearg and Sgorr Dhonuill.

Go past the school and climb Schoolhouse Ridge, where rocky walls require hands-on scrambling. Continue over Sgorr Bhan to Sgorr Dhearg. Descend west-southwest to the intervening bealach, then climb Sgorr Dhonuill, whose final approach has simple scrambling and an exposed section. Return to the same bealach, descend north beside the old fence line, and follow the forest paths and tracks. The lower broad track is followed right rather than towards Glenachulish car park. Return by the A82 pavement near St John’s Church and the village road to the original car park.

This is a strenuous mountain circuit, not a short single-summit walk. The alternative ascent via Beinn Bhan avoids the Schoolhouse walls but is steep, boggy and partly pathless. No separate totals are established for that variation or for a Sgorr Dhearg-only outing. A full-pair variation still encounters the Sgorr Dhonuill exposure.

Terrain and preparation

Narrow grassy and rocky ridges, loose ground, boggy descent and complex forest junctions all require attention. Wet rock, strong winds and cloud can make the scrambling substantially harder. Carry map, compass and backup navigation, food, water, warm layers and waterproofs. Allow enough daylight. Snow and ice require winter skills and equipment.

Check current Forestry and Land Scotland notices for working-forest restrictions and follow signs or temporary diversions. The active Glenachulish management plan confirms the forest context but does not guarantee every path is open. Use the pavement on the final A82 section.

Rock, views and name

The Edinburgh Geological Society field guide traces Appin Quartzite to Sgorr Dhearg’s summit. The surrounding Ballachulish igneous complex and contact aureole contain varied igneous and metamorphic rocks; a blanket granite description is misleading.

The ridge gives views over Loch Leven towards the Mamores and Ben Nevis, along Glen Coe and towards Loch Linnhe. Glencoe Folk Museum translates Sgorr Dhearg as Red Peak and discusses Thunderbolt or Dragon interpretations of Beinn a’ Bheithir. Its Ballachulish Dragon story is folklore.

Getting there

Check the village car park’s current signs, charges and capacity. Glenachulish car park is a different start. Village shops and toilets are subject to opening hours; carry supplies for the entire mountain day.

Shiel Buses’ route 44/144 pages list Ballachulish Square on the Fort William–Kinlochleven corridor. School days, holidays and weekends have different timetables. Check both directions and the last return: a bus itinerary may not fit a 7–9 hour walk with delays. Do not assume a coach stopping at North Ballachulish serves the village start.
