Fancy bouldering underwater, floating up holds? Try 'The Ark' blocs at Loch Arklet, beside the Stronachlachlar boulders. Usually submerged, they emerge clean and smooth and rippled in late summer, when the thirsts of Glaswegians drain this feeder loch enough to reveal a pair of conjoined blocs. There are a few nice sit starts on perfect schist, with a tough wee roof on 'The Arklet'. Being 3 minutes from the road, they are a perfect summer's picnic venue, with often a breeze rippling the loch to keep the midges to the higher blocs in the bracken up at An Garadh.
