|Route outline (key)|
The B872 follows the old A814 route through Garelochhead. The village at the head of the Gare Loch was bypassed as part of the military's road scheme to provide access from the A82 to Faslane and Coulport bases, with the first section west of the A82 given the A817 number.
The route starts at a roundabout outside the Faslane Base to the south of the village, quickly returning to the coast and so follows the shore line into Garelochhead. At low tide, a large shingly beach is exposed to the left, but quickly hidden by a block of shops and houses as the road passes through the small village centre. Running further inland, the B872 turns round to the left and passes along a tree lined avenue with parkland to the north. At the end it meets the B833, gateway to the popular Rosneath Peninsula, at a T Junction before turning north again. For a few years the B872 ended here and the B833 continued along the pre-bypass A814 but now the reverse is true. The road climbs steeply out of the village and passes through a wood to reach the Whistlefield viewpoint, after which it cross the West Highland railway Line to end at a roundabout back on the A814. The unclassified road to the left is the military road to Coulport mentioned above.
