This article is about the current B727 insouthern Kirkcudbrightshire.
For the original B727 from Dalbeattie to Castle Douglas in the same county, see B727 (Dalbeattie - Castle Douglas).
The B727 starts on the A755 to the west of Kirkcudbright, and heads south west along the shore of the River Dee as it flows out into Kirkcudbright Bay. The road winds along the coast, twisting and turning, it is not a road for fast driving. Just after a small car park, the road turns inland, the bends ironed out a little as it climbs steadily up to Borgue, a small village which is nevertheless the largest on the route. Turning sharply north in the village the road winds and undulates for another 2 miles or so before reaching the A755 again.
After nearly a mile multiplex with the A755, the B727 resumes on the far side of the A75. This is the old route of the A75, heading into Gatehouse of Fleet, where it runs the length of the High Street and crosses Fleet Bridge to terminate on the B796.
