Northwest of Loch Chon, the B829 climbs gently from the plantings to open moor with a breathtaking vista over Loch Arklet to the Arrochar Alps, the name given to the high hills west of Loch Lomond. Hidden from sight in a deep trench, Loch Arklet is dammed to feed Loch Katrine. Go left at the road junction (a right will take you to the village of Stronachlachar) and take the open road along Loch Arklet. These deserted green hills were once the rallying grounds of the Clan Gregor. Near the dam on Loch Arklet, on your right, Garrison Cottage recalls the days when the government had to billet troops here to keep the MacGregors in order.
From Loch Arklet the road zigzags down to a T junction. To the left is Inversnaid, with Loch Lomond stretching out of sight above and below. Right at the junction is the hamlet of Stronachlachar, on Loch Katrine, the outermost landing stage for the SS Walter Scott's trips on the loch. Stop while you are there for lunch or coffee and cakes at the Pier Tea Room.
