Gaick Pass

Gaick Pass is a 21.4-mile one-way crossing from Dalnacardoch Lodge on the A9 to Tromie Bridge in Glen Tromie. It traces an old drove road through Glen Edendon, skirts Loch an Dùin and Loch Bhrodainn, crosses the central pass by Gaick Lodge, then turns down the River Tromie. Allow around nine hours of walking; the length makes this a full-day undertaking even though the route has little steep climbing. Tromie Bridge is the finish for this trail. Continuing toward Kingussie adds another section and extra miles, while the nearby Gaick Corbetts Circuit is a different outing.

Arrange a finish pickup before you start: this is a through-walk, not a circuit. The southern access is beside Dalnacardoch Lodge on the A9, and the route crosses the busy dual carriageway. No dedicated parking or services were confirmed at either end, so plan the transfer rather than relying on a trailhead lot. No food or water stop was verified along the route. Dogs are allowed under Scotland’s access rules; keep them close on moorland and near livestock, especially during the bird-breeding season.

A good track runs north for about 9 km through a plantation, past a radio mast and alongside Edendon Water to Sronphadruig Lodge. From the lodge, the route changes character: a faint path crosses boggy moorland, then rejoins a clearer track along the west shore of Loch an Dùin. The loch lies below An Dùn’s steep slopes, which rise about 300 m from water to summit. At the north end, cross Allt Loch an Dùin either at the wider, slower outflow or at the narrower, faster track ford. Choose only a crossing that is safe at the current water level.

Beyond the loch, Domingo’s Road heads northeast through the pass. The track becomes rough near Loch Bhrodainn, followed by substantial fords near the loch and at Allt Gharbh Ghaig. Both can be difficult in wet conditions, so don’t treat a recent dry crossing as a promise about the next one. The route passes remote Gaick Lodge by Loch an t-Seilich; snow can cut off the lodge in winter, when avalanche danger also matters.

The pass is an old drove road, and the alignment appears on an early six-inch map of the area. Near the lodge, a memorial marks five members of a hunting party who died when an avalanche buried their bothy in January 1800. It gives the quiet central section a stark bit of history; leave a few minutes to find and read it.

Past Loch an t-Seilich, reach Allt Bhran bridge, where the route joins the Minigaig, then follow a track east of the River Tromie past Lynaberack Lodge to Tromie Bridge. The sampled elevation profile rises from about 330 m near Dalnacardoch to roughly 520 m on the route, then drops to around 250 m at the finish. At the north end of Loch an t-Seilich, look back into the Gaick: the loch and track make a strong foreground for the hills. The journey is about steady mileage, boggy ground and water crossings, not a summit scramble.
