Solo. From start of track at NO260981. After ascending An Creagan and Tom Breac descended to footbridge at NJ212019 and up track to ruin of Loch Builg Lodge. A useful path rises from Loch Builg Lodge and passes not far below the summit of Carn Tiekeiver. I used this to a large extent on the descent but less so on the ascent as the line of the path is difficult to ascertain in its lower parts. Heather is encroaching on the path. Needs more ascents! Returned to starting point via Corndavon Lodge. Beautiful warm and sunny day.
