Sunday 6th January 2019 Maps 40 & 49, NM873605 Glen Tarbert Creach Bheinn (853m, Corbett) — plunder hill, Meall Odhar (794m, Corbett Top) — dun-coloured hill.
This route explores the possibility of access to and egress from these hills facilitated by the recently constructed hydro schemes in Coire Dubh and Coire nam Frithallt. Start from the lay-by on the A861 approximately mid-way between the two power stations at NM873605. Head W down the road on a wide verge to the hydro track at NM868605. Head S on the track, across the Carnoch River and up into Coire Dubh. Continue to follow the Allt a’ Choire Dhuibh to a confluence at NM871595. Climb S up a ridge on the E side of the tributary to reach a gap in the steep corrie wall that gives acess to the open hillside above. A fence-line may assist identification. Turn SE and climb up to Creach Bheinn following the edge of the rim of the corrie. When abreast of the Bealach Coire an Dubh-alltan at about NM874581, turn SW to the summit trig point. Return and descend E to the Bealach at 714m, continuing E up to the summit of Maol Odhar. Head SE, curving NE around the rim of Coire nam Frithallt, down to a col, then up to a small summit, 715m. Turn N and descend a broad ridge until it levels at about 500m alt, then descend NW, crossing the fence-line to reach the Allt Coire nam Frithallt. Follow it downstream to reach the hydro track and continue to the A861. Walk E along the verge back to the lay-by. (13km, 950m ascent)
